REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of U.S. patent application Ser. No. 13/847,469, filed Mar. 19, 2013, which claims the priority of U.S. Provisional Patent Application No. 61/614,465, filed Mar. 22, 2012, the entire contents of each of which are incorporated herein by reference. 
    
    
     FIELD OF THE INVENTION 
     The invention relates to the field of faucet assemblies and internal faucet water way assemblies and components thereof. More particularly, the invention relates to such faucet assemblies and internal faucet water way assemblies, wherein a portion of the internal waterway assembly of the faucet is formed of a polymeric or composite material. 
     BACKGROUND OF THE INVENTION 
     Traditionally, faucet assemblies have been formed with copper and/or brass internal water way structures. The structures fit under a metallic outer cover plate structure which may have a separate faucet spout or outlet portion having various internal faucet water way configurations for delivery of water from within the faucet assembly base to the outlet through an aerator or similar outlet in the spout. Such internal structures are supported by and/or are built within an internal metallic support base which may also have a separate putty plate. Such faucet assemblies are mounted to a mounting surface using mounting methods known in the art. Over time, cost and expense of using metallic parts has given rise to attempts to create internal water way structures or other parts within a faucet assembly, such as within a valve cartridge of a faucet assembly or within the exit portion of the faucet assembly of polymeric materials. 
     Also in an attempt to create new design possibilities and provide a different option installation, some manufacturers have developed spread faucet assemblies wherein individual portions of the faucet (valve assembly or spout) are not within a standard faucet cover and base, but are each independently mounted on a mounting surface and connected using various mechanisms beneath the mounting surface. Such structures tend to be more complex to install than a standard faucet structure with the internal water way structure located under a common cover within a housing. 
     In designing such new faucet structures that may include polymeric molded pieces, molding of the internal pieces while maintaining a sanitary and securely connected internal water way structure has given rise to various configurations. When the exterior configuration or shape of the faucet housing changes, the internal water way structure and the interior of the faucet assembly outlet faucet portion must be reconfigured to work within various outer structures. 
     U.S. Pat. Nos. 7,793,677 and 7,406,980 show what is identified as a connecting water way structure which may include plastic which extends between a valve body section and a faucet spout portion. A bridge faucet with an elevated bridge extending above the mounting surface of the sink is taught as well in U.S. Pat. No. 8,011,384. The patent describes a way to connect a faucet spout to the elevated bridge using a coupler having a rod that can be actuated by a tool from its upper end. 
     U.S. Publication No. 2011/0259456 A1 discloses a polymeric bridge for a lavatory faucet. The faucet has a coupler that is molded plastic and includes two valve supports molded within the coupler and two valve interfaces extending upwardly to receive a gasket. An outlet tube sits within the spout and the tube connects into the bridge. Hot and cold water inlet tubes are over-molded into the device so that the water can flow through the over-molded inlet into the connector and into the coupler to a central outlet. A method for molding a water way is also included in which tubes and mandrels are used to form valve interfaces. 
     Chinese Patent Application Publication No. 201475416UA teaches a core body structure for a faucet bridge that has a molded three-way bridge insert and then a secondary molded water channel body molded over the bridge insert. The body and insert have a through hole and a water outlet for a faucet tube. The end surfaces of the three-way bridge insert are each provided with a curved surface structure to mate with a vertical shank or pipe. The outer surface of the three-way bridge insert after secondary molding is completely embedded in the molded water channel body. This faucet helps save cost of metallic parts but must be formed by pre-assembly and two-part insert molding for different size faucet designs. The placement of the curved surfaces of the bridge insert against the shank or pipes holds the bridge steady but allows for the faucet tube attachment in only a single molded location once secondary molding has the entire body structure fixed. 
     Thus, while there are prior art structures incorporating polymeric materials in one or more features of a water way assembly, or forming a over-molded valve structures connected to inlet and outlet tubes for water supply, there is still a need in the art for an improved, flexible design using polymeric materials or formed as a hybrid structure incorporating both metallic and polymeric materials, that minimizes the use of copper and/or brass materials in the faucet assembly except if desired, for example in a high pressure water way area, is easy to assemble and install and keeps manufacturing costs low by eliminating some of the complexity or large number of internal parts in an internal water way assembly of a faucet assembly. Further, a need in the art exists for such faucet water way assemblies, wherein such assemblies have simplified manufacturing options and versatility, while maximizing the ability to provide a wide variety of faucet design configurations using only a few basic and standard component parts.

     DETAILED DESCRIPTION OF THE INVENTION 
     The faucet assemblies herein provide unique options for economical and versatile product design. The faucet assemblies include internal water way assemblies including a valve assembly and bridge that work together in embodiments discussed herein to provide such advantages. Each valve assembly and/or the bridge preferably has one or more extending taps or connectors that enable attachment of the internal water way assembly via the valve assembly(ies) and/or the bridge directly to the cover plate of the faucet assembly. Such direct connection eliminates the need for a support plate which is a standard feature of most faucet assemblies. 
     In further embodiments, the valve assemblies are preferably formed independently of the bridge structure. The bridge can then be positioned with respect to the valve assembly(ies) prior to attaching the valve assembly(ies) to the bridge by rotating the bridge so that the opening that receives the spout tube when the spout tube is attached can lie at a variety of angles. The bridge may also be further angled frontwards or backwards along the horizontal x-y plane of the faucet and/or upwards or downwards in the direction of the z axis as noted and discussed elsewhere herein. Thus, standard valve assemblies may be used and rotatably positioned and then attached to various standard bridge configurations to create a wide variety of valve/bridge combinations. A further variety of spout tube designs may be used with the valve/bridge combinations. Thus, use of only a few standard parts enables a modular approach to more automated and simple manufacture of faucet assemblies in a wide variety of design configurations and differing sizes. It further provides easy formation of hybrid faucet assemblies which are at least partially polymeric for ease of manufacture and cost reduction. 
     In one embodiment herein all or a portion of a separate valve assembly may be attached to a bridge component, either removably or permanently, so as to form a primarily metallic internal water way assembly having shank(s), valve water way portion(s) and the bridge formed of a metallic material. In another embodiment, a shank and valve water way portion, each formed of a metallic material may be provided as a valve assembly for use with a bridge formed of a polymeric material. In further embodiments, varying bridge components (formed of metallic material and/or polymeric material) may be provided to work with varying valve assemblies, such as, for example valve assemblies which may include (a) a shank and valve water way portion that each include polymeric material which can communicate with standard polymeric inlet/outlet hose(s); or (b) a metallic shank sleeve connectable to inlet/outlet hose(s) with a valve water way portion having a polymeric outsert-molded material overlying or forming the valve water way portion and/or forming an interior layer on the interior surface of the shank. 
     The invention further provides a spout tube which is preferably polymeric and can be made flexible in nature if desired. The spout tube when assembled to the bridge herein extends from a spout inlet along the bridge. The bridge, in a preferred embodiment herein, is positioned within the internal water way assembly such that it is mechanically joined to or engaged within the valve water way portion of the valve assembly. This allows for an interior water way assembly which can be adjusted prior to assembly so as to fit within a variety of outer cover plate designs or faucet exteriors, while not requiring separate interior constructions for each such exterior design modification. This ability to use a basic internal water way assembly, but vary the positioning for different cover plates using a bridge that can work with the spout tube so that it is repositionable in assembly, enables the spout outlet to be repositioned or modified in varying ways to achieve a variety of spout reaches and heights and varying cover plate designs. 
     The manufacture of a separate side valve assembly(ies) in a hybrid faucet assembly provides a more universal internal water way assembly in embodiments herein which is also beneficial, as coupling such assemblies to various differently sized or configured sink fittings can be accommodated by using such universal valve assemblies with different center bridge configurations and sizes, for example, using the valve assemblies with different bridges to form both four inch and eight inch faucet water way assemblies. 
     Incorporating polymeric materials in the internal water way assemblies of the faucet assemblies herein not only provides flexibility in design as noted above, but contributes to reduction in the amount of brass and/or copper material used for various parts such as the water way, resulting in reduced product costs, reduced weight and, easier maintenance. 
     Thus, the embodiments herein provide a modular approach that allows for simple molded internal water way components and eliminates the need for complex internal water way molding techniques such as plastic injection with soluble cores or gas assist molding processes and/or various primary insert and secondary molding techniques. It further contributes to a lower overall product manufacturing and consumer costs. 
     Referring now to the Figures herein, preferred embodiments of the invention will be described. In the drawings, words such as “inner” and “outer,” “upper” and “lower,” “interior” and “exterior,” “forward” and “backward,” “front” and “back,” “left” and “right,” “upward” and “downward” and words of similar import are intended to assist in understanding the preferred embodiments of the invention with reference to the accompanying drawing Figures with respect to the orientation of the faucet assembly as shown, and are not intended to be limiting to the scope of the invention or to limit the invention scope to the preferred embodiment as shown in the Figures. 
     In one embodiment herein, as best shown in  FIGS. 1-13 , a faucet assembly, generally referred to herein as faucet assembly  10 , is shown which is a lavatory faucet assembly. This embodiment should not be considered to be limiting and is for illustration purposes in understanding the nature of the invention. In a general sense, the faucet assembly includes a cover plate herein shown as cover plate  12 , an internal water way assembly  14  and one or more faucet handles  16 . The cover plate as shown is in the nature or format of a lavatory faucet and is a multi-part cover plate. However, the cover plate  12  may have a variety of configurations and shapes, without limitation herein and may be unitary if desired. It may also be shaped so as to be suitable for use in a kitchen faucet, industrial sink faucet, laundry sink faucet or any other faucet assembly configuration. 
     The cover plate  12  as shown has a configuration for use with a lavatory faucet design in which for assembly purposes it is convenient to form an outer shell for housing an assembled internal water way by using two separate cover plate pieces. However, it should be understood to one skilled in the art in view of this disclosure that a one-piece cover plate or lower cover plate over just the bridge and valve assemblies with a separate covering for the spout tube may also be used as exemplified further below in this disclosure. A top cover plate  18  and a bottom cover plate  20  are preferably configured so that when assembled, they have a smooth mating appearance. The cover plate  12  defines an interior surface  22  on both plates that defines an interior space  26  in which at least the bridge and valve assemblies of the internal water way assembly are generally situated, and as shown here, also accommodates the spout tube. 
     The exterior surface  24  of the cover plate may be formed so as to be of a variety of preferably decorative materials, whether a metallic cast finish, a plastic molded design color or metallic look or the like. The cover plate may also be a molded metallic structure, but is preferably a molded polymeric material having a cast metallic finish. Such materials are well known in the art of exterior coverings for faucet assemblies, and any such suitable outer faucet cover material may be used to form the pieces of the cover plate, such as the polymeric and composite materials listed elsewhere herein. Preferably, the cover plate is formed of a polymeric material such as a polyoxymethylene (POM), a polyamide (PA), a polyphenylene sulfide (PPS), or a polyphenylene oxide (PPO) or combinations, copolymers or functionalized forms of these polymers of various other polymers as listed elsewhere herein. 
     The top and bottom cover plates  18 ,  20  of the assembled cover plate may fit together in a variety of ways. Either of the cover plates may have a bore formed in the structure to receive a mating and interlocking piece, or a fastener, dowel, snap-fit piece and the like. As best shown in  FIG. 13 , the top cover plate is provided with female receiving bores  28  having an interior surface  30  configured to receive a male fastener such as fasteners  32 . The fastener(s) may pass through and/or be situated in a receiving hole in the bottom cover plate or elsewhere in the water way assembly so as to fit within the mating bore  28  in the interior surface  30 . Alternatively, a mating projection(s) may be formed in a surface of the lower plate or attached to the water way assembly instead of a separate fastener(s), which projection(s) would be sized and configured to be received in the receiving bore(s) in the top cover plate. The location of the bore(s) and the fastener(s) or projection(s) that can fit within the receiving bore could be reversed as well in terms of whether each is located on the top plate or the bottom plate. It should also be understood to one skilled in the art, based on this disclosure, that any suitable interlock feature for mating polymeric cover plate parts may be used within the scope of the invention, including peripheral tabs or other mating interlock features to facilitate a tight fit such as an interlocking feature  34  in the form of a tab shown in  FIG. 13 . Further, it should be understood that while two mating plates are preferred for formation of the cover plate  12 , it can also be formed as a molded unitary structure or of a lower base plate cover and an upper spout tube cover. 
     As shown in various cross-sectional views in  FIGS. 2-6 , the exposed bottom view of the faucet assembly without the bottom plate in  FIGS. 9 and 10  and in the exploded views of  FIGS. 11-13 , the faucet assembly  10  also includes an internal water way assembly  14 . The internal water way assembly  14  preferably generally includes one or more valve assembly(ies)  36 , a valve cartridge(s)  46 , a bridge  38  (which may be a single piece or a multi-part assembly) and a spout tube  40 . 
     The valve assembly further may incorporate one or more shanks  42 , and one or more valve water way portions  44 . The valve cartridge(s)  46  is/are then seated in the valve water way portion(s) of the valve assembly(ies). A shank  42  in the valve assembly herein may be formed in a standard shank configuration preferably having a partially or fully threaded exterior surface  48 . Such surface can then be used to mount the faucet assembly  10  to a mounting surface M using any suitable mounting nut  50  as shown in  FIG. 1 . A standard nut or a quick push and turn nut as disclosed, for example, in U.S. Patent Publication No. 2010/0272503 A1, incorporated by reference herein in relevant part, may be used for installation against a mounting surface. Hot and/or cold water inlet tubes as are known in the art may also pass through the longitudinally extending interior passageway  52  within the shank for connecting the faucet assembly to a water source. Such tubes are known in the art. Alternatively, the shank may be molded of a polymeric material so as to have an internal configuration for desired flow patterns, flow pressure or degree of turbulence. The shank may also be connected directly to a standard water supply hose for supplying hot or cold water if two shanks are used, or for housing a mixing valve which may also then be connected to hot and cold inlet hoses for a single handle faucet. Such connections are well known in the art and so are not explained in detail herein. 
     Each shank  42  in each valve assembly  36  may be formed together with the valve water way portion  44  as a single unitary body, or may be a separate piece to which a separate valve water way portion  44  may then be attached such as by molding, welding or mechanical attachment. As a unitary structure, the shank  42  and valve water way portion  44  may be formed of a single material and shaped or molded as a single part. In doing so, the combined structure of the shank and valve water way portion could be formed of a material which is a metallic material, such as a metal or metal alloy, preferably brass, copper, steel or plated steel. Alternatively, they combined unitary structure may be molded from a polymeric material. In addition, a metallic base structure may be formed over which a polymeric material may be provided to the exterior and/or interior surfaces if desired, such as a polymeric outer covering on a metallic base in the valve water way portion or a polymeric lining in a metallic shank. 
     Polymeric materials used may be an unfilled polymer or a filled polymeric or composite material having a powder type or fibrous reinforcement. Various polymer and/or hard rubber materials may be also used (e.g., polystyrene-butadiene-styrenes (SBS), polyacrylonitrile-butadiene-styrenes (ABS), polyamides (PA), polyimides (PI), polyarylenes (polyetherether ketone (PEEK), polyether ketone (PEK), polyether ketone ketone (PEKK) and the like), polyethylene sulfones (PES), polyetherimides (PEI), polytetrafluoroethylene (PTFE), fluoroplastics (FEP and PFA), olefinic rubbers, polyethylenes (PE), polypropylenes (PP), polyvinylchloride (PVC), polyoxyalkylenes (i.e., polyacetals) such as POM, polyoxyethylenes (POE), polyoxybutylenes (POB), polyphenylene sulfide (PPS), polyphenylene oxide (PPO), etc., styrene-maleic-anhydrides (SMA)). The shank and valve water way portion may be formed of other similar molding materials, composites, blends and/or copolymers of these materials, provided the materials provide adequate strength and properties for functioning in the faucet assembly  10  herein. Composite materials may include a combination of polymeric materials as noted above with fibrous and/or particulate materials such as glass fibers, carbon fibers, aramid fibers, Kevlar®, mica, carbon powder, and other fillers known in the art. As noted above, preferred materials include PA, POM, PPS and PPO and copolymers, combinations and functionalized polymers of these materials. 
     It is also within the scope of the invention as noted above that the shank and valve water way portion are separate pieces combined into a single structural unit. In one embodiment, the shank may be formed of a metallic material and the valve water way portion then molded over the upper portion  54  of the shank  42 . Techniques such as outsert molding or other heating molding processes for forming a valve water way portion  44  on an upper portion  54  of a shank  42  may be used. In preparing such a structure, it is preferred that the polymeric material used to form the valve water way portion  44  is also coated on the interior surface  56  of the shank  42  to form a smooth interior and a uniform transition from the longitudinally extending interior passageway  52  of the shank to the interior of the valve water way portion  44 . Thus, there are multiple options for formation of the valve assembly pieces so as to provide a variety of design options. 
     The shank and/or valve water way portion  44  of the valve assembly  36  are preferably formed as a separable assembly that may be attached permanently or removably to the remainder of the internal water way assembly  14  and can be configured to seat a variety of valve cartridges. The valve assemblies may be further molded or formed so as to connect the valve water way portion  44  to the bridge  38  and shank forming a three-piece unitary structure after the bridge is rotatably positioned. Such molding may be done to enhance structural integrity. In the preferred embodiment shown herein, the bridge  38  and the valve water way portion  44  are mechanically joined or engaged and the bridge is a separate piece from the valve assembly  36 . By maintaining the valve assembly as a separate feature that may be combined mechanically to the bridge, modular water way assemblies may be formed wherein a standard valve assembly may be used, and also incorporate various types of cartridges if desired. The standard assemblies can be interchanged with different size and shape bridge configurations to form multiple variations of water way assemblies. By rotating the bridge before assembly to different positions, the water way assembly can attach to various shapes of spout tubes using a variety of heights and elevations depending on where the spout receiving portion of the bridge is aligned with the spout tube. 
     The valve water way portion  44  may have a variety of configurations on its exterior for either aesthetic or design reasons, but the exterior surface  58  of the valve water way portion  44  is preferably generally cylindrical and shaped so as to fit over and be positioned on the upper portion  54  of the shank  42 . Internally, the interior surface  60  of the valve water way portion  44  should be configured to define a valve seat  62 . The valve seat is preferably configured to receive water from a water source that would flow through the passageway in the shank from a water source into the valve seat in the valve water way portion. The shape or configuration of the valve seat can vary depending on the valve cartridge  46  to be used. A valve cartridge  46  may be any of a variety of standard commercially available or otherwise manufactured valve cartridges known in the art or to be developed. The valve cartridge  46  shown herein is preferably a valve cartridge having the design and configuration as described in U.S. Patent Publication No. 2012/0273075 A1 which is commonly owned with this application, and the disclosure of which is incorporated herein by reference in relevant part with respect to the design configuration of the cartridge. Such a cartridge is also commercially available from American Standard Brands of Piscataway, N.J. as the Washerless Ceramic Disc ECO™ Valve or Lifetime ECO™ valve. Thus the valve seat would be configured to securely hold the cartridge and to have an opening in the valve seta in communication with an opening in the cartridge for receiving water into the cartridge. The precise configuration of the valve seat and cartridge combination as well as any interlocking or sealing arrangements can be varied within the scope of the invention and should not be considered limiting. 
     The cartridge  46  as best shown in  FIGS. 5 and 13  may be actuated by an upper end  64  thereof. The upper end of the cartridge is preferably provided with features, such as a spindle  66  and/or stops  68 , so that the faucet handle  16  can have an interior surface  70  with corresponding features, such as feature  72  shown in  FIG. 5  for example, that operably move the valve cartridge. As shown, a feature(s)  72  operates to engage the valve cartridge spindle  66  so that it may be moved from an open to a closed position and/or into a partially open or partially closed position for adjusting overall water flow and temperature between hot and cold water flow. The valve cartridge thus moves through different positions so as to control flow through the internal water way assembly. The handle(s) also are preferably positioned as shown to be outside the interior space defined by the interior surface of the cover plate. Such cartridge and handle configurations are known in the art and any suitable cartridge/handle combination designed to fit in a valve seat as described herein that is known or to be developed may be used within the scope of the invention. 
     As best shown in  FIG. 6 , the valve water way portion  44  further includes an inlet  74  to receive water flow from the longitudinally extending passageway  52  of the shank  42 . Water enters the valve water way portion inlet  74  and enters the valve seat  62 . Water passes into the valve seat  62  and into the inlet  76  of the valve cartridge  46 . The inlet  76  of the valve cartridge is situated and configured for receiving water entering the valve seat if and when the valve cartridge is in an open position. After passing through the cartridge  46  when open, water flows out of at least one side cartridge outlet  78  and flows within the interior of the valve seat. The valve water way portion  44  includes in the embodiment shown a transversely extending outlet passageway  80  which is preferably at least partially within a bridge receiving portion  82  extending outwardly towards the center of the assembled internal water way after the valve assembly is installed and the assembly completed. If the valve water way portion is alternatively formed and then molded to the bridge, the transversely extending outlet passageway leading water flow from the valve water way portion could be heat molded onto the bridge so that flow from the valve water way portion goes directly into the bridge. 
     As shown in  FIG. 6 , the bridge receiving portion  82  has an interior surface  84  which is configured for engaging and/or joining to one end  86   a  of the bridge. The surface  84  can have mating features for a snug fit and preferably includes a groove  88  for receiving a seal  90  such as an o-ring or gasket therein. The outlet(s)  78  of the valve cartridge  46  are thus in fluid communication with the outlet passageway  80  of the valve water way portion  44 , and more specifically with the interior of the bridge receiving portion  82 . 
     The water leaving the bridge receiving portion(s)  82  flows into the open end(s)  86   a ,  86   b  of the bridge  38  such that the outlet passageway(s)  80  of the valve water way portion(s)  44  is/are in fluid communication with the passageway  96  of the bridge  38 . The open end  86   a  of the bridge is positioned within the bridge receiving portion  82 . The bridge  38  is preferably generally transversely extending across the faucet assembly  10  as is the bridge receiving portion  82  for a more laterally aligned standard faucet, but it is within the scope of the invention that the bridge could be configured so as to extend upwardly in a more curved or angled configuration, backwardly, forwardly, upwardly or downwardly with respect to the x, y and/or z axes of the bridge within the assembly (see  FIG. 12 ). Preferably, however, the bridge  38  is formed so as to generally extend from side-to-side or generally transversely within the faucet assembly, wherein “generally transversely” accommodates variations in angle but generally extends side-to-side. The bridge as best shown in  FIGS. 9, 10, 12 and 13  has slight bends. Such bends may be provided for design purposes so as to follow the outer configuration of the faucet assembly and/or for flow purposes for directing flow from the valve water way portion and bridge receiving portion into and through the bridge and upwardly out of the bridge into the spout tube. The bridge may also be provided with curves or outer features if desired. 
     As shown in  FIG. 12 , the bridge  38  may have a slightly bent angle α of greater than 0° to about 10° between the x and z axes (i.e., an upward vertical angle to the horizontal or transverse axis (x-x) of the apparatus and/or to the x-y horizontal plane) and as best shown in  FIG. 9  in a bottom plan view a backwardly extending angle β of greater than 0° to about 10° between the x and y axes. As shown, a slight curve is also provided. This is just one of several such configurations that the bridge may have, and should not be considered limiting to the scope herein. Depending on the configuration of the bridge, the bridge receiving portion of the valve water way portion may be designed to have a slightly angled arrangement with respect to the body of the valve water way portion to more smoothly mate with the bridge if desired for design purposes. 
     The bridge also has a passageway therethrough extending generally transversely from one end of the bridge, extending into the interior passageway within the spout receiving portion when there is only one valve assembly, or extending further and ending in an opposite end of the bridge as shown. The opposite end of the bridge  86   b  is thus configured in the embodiment shown to be placed in a second valve water way portion of a second valve assembly when two valve assemblies are used. As shown, the bridge  38  has an internal passageway  96  defined by its interior surface  98  and extending through the bridge from one inlet end  86   a  to the other  86   b . The open inlet ends of the bridge are in communication with the passageway  96  through the bridge  38 . The passageway  96  receives water from the outlet passageway  80  of the valve water way portion  44 . 
     If two valve assemblies are used as shown with two valve water way portions, the second opposite end  86   b  of the bridge engages with or is joined to a second bridge receiving portion  82  on a second valve water way portion  44 . It may be engaged or joined so as to be releasably attached or permanently attached. To accommodate this, the exterior surface  97  of the bridge  38  at the ends  86   a ,  86   b  can be configured to fittingly engage, preferably snugly the interior surface  84  of the bridge receiving portion  82  or may have features for interlocking with similar mating features on the interior surface  84  of the bridge receiving portion. As shown, a seal  90  is seated between each of the ends  86   a  and  86   b  in the groove  88  formed in the interior surface  85  of the bridge receiving portion  82  for sealing engagement of the bridge receiving portion  82  and the bridge  38 . Further, an outwardly extending flange  89  is positioned around the exterior surface  97  of the bridge at the ends  86   a ,  86   b  such that when each end  86   a ,  86   b  is positioned within its respective bridge receiving portion  82  of each valve water way section  44 , the flange helps seal and lock against the edge  91  of each of the bridge receiving portions  82 . The inlet ends of the bridge may also be permanently attached by an adhesive or the like to the interior surface  85  or edge of the bridge receiving portion. In addition, the configuration of the ends  86   a ,  86   b  and the bridge receiving portions  82  may have a flipped configuration in which the bridge receiving portions are instead configured to fit within the bridge ends instead of the other way around so that the bridge receiving portions fit within the respective ends of the bridge. In such an arrangement, the sealing groove may be formed within the ends of the bridge and the interlocking features reversed. Interlocking features may include flanges as shown, snap-fittings, locking tabs, interlocking mating features, slots and tabs, bayonet lock connectors, and the like, and the manner in which the pieces interlock or fit together should not be considered limiting to the invention. 
     Water flowing through each of the outlet passageways  80  of each of the opposite valve water way portions  44  travels toward the center such that each of the flow paths flow toward each other as shown by flow arrows f 1  and f 2  in  FIG. 11  until the flow meets, which as shown is at a center area A of the bridge  38 . The merged flow from each valve assembly then enters the internal passageway  94  of the spout receiving portion  92  of the bridge and flows upwardly into the spout tube  40  along flow path f 3  shown in  FIG. 11 . The interior surface  100  of the spout receiving portion  92  of the bridge defines an internal passageway  94  extending through the spout receiving portion  92  that is open to the passageway  96  of the bridge at one end and open as an outlet at the other end for allowing flow from within the bridge passageway  88  to exit the bridge  38  through the internal passageway  94  of the spout receiving portion  92 . 
     The bridge exterior shape may be formed so as to have a variety of external cross-sectional shapes, including generally round, elliptical, oval, square and the like. Similarly the various internal passageways in the bridge receiving portion of the valve water way body and within the bridge may have a variety of cross-sectional shapes that may be the same or different from the exterior cross-sectional shape of the exterior of the bridge. Thus the exterior may be formed for manufacturing convenience and fit within the cover plate, yet may have a configuration in the interior of the passageway in cross-section that is best suited for desired flow characteristics, for example a more generally round interior cross-section. 
     The spout tube of the faucet assembly can be formed of a variety of polymeric materials including composites, or of metallic materials as noted above herein. Preferably the spout tube is formed of a moldable and/or flexible polymeric material. If a flexible material is used instead of a more rigid polymeric molded material, the spout tube can also be manipulated so as to fit within the interior space of the cover plate. Alternatively, it can be pre-molded to fit using a less flexible molded material and a pre-formed design configuration. As shown, the spout tube is molded so as to generally conform so as to fit efficiently within interior space  26  formed by the interior surface  22  of the cover plate  12  in the area B as shown in  FIG. 1  where the top and bottom cover plates  18 ,  20  meet to form the spout portion  102  of the cover plate  12 . The spout tube has an inlet end  104  open to flow which inlet end is configured to be positioned in the spout receiving portion  92 . With reference particularly to  FIGS. 4 and 13 , preferably, if molded, the spout tube has exterior features on the exterior surface  105  of the spout tube at the inlet end  104  thereof for engaging with and/or joining the inlet end  104  to the interior surface  100  of the spout receiving portion  92 . As shown, the faucet assembly  10  includes an example of a locking end  106  having a groove  108  therein for receiving a seal  110  such as an o-ring or gasket in the groove  108 . However, other locking features or mating features, including locking plates or flanges to hold the inlet end of the spout tube within the spout receiving portion, may be used and/or formed into or on the exterior surface  105  of the spout tube within the scope of the invention. It is also within the scope of the invention that the bridge receiving portion fits within the inlet end of the spout tube in a reverse configuration wherein the bridge receiving portion forms the female mating end of the connection and o-ring placement and/or locking features are reversed. 
     Once the spout tube  40  is seated within the spout receiving portion  92 , flow through the internal passageway  94  of the spout receiving portion leaving the bridge also flows within the inlet end  104  of the spout tube. Thus the inlet end  104  is in fluid communication through the spout receiving portion  92  with the passageway  96  of the bridge  38 . The spout tube  40  also has a second, outlet end  112  for delivering water out of the faucet assembly when in use. The outlet end  112  may be configured to accommodate an internal aerator, sprayer, an open flow/spray flow diverter and/or extendible hose for a pull-out sprayer feature depending on the faucet assembly intended use and design. As shown, an interior surface  114  of the outlet end  112  is configured to have threads  116  for receiving an end fitting (not shown) such as an aerator or the like with similar threads. However, any end fitting receiving or other outlet end configuration is within the scope of the invention hereof and the outlet end configuration should not be considered limiting to the invention. Flow thus enters a passageway  111  through the spout tube defined by the interior surface  109  of the spout tube  40  at the inlet end  104  along a flow path according to arrow f 3 , travels through the passageway  111  of the spout tube and exits the faucet at the outlet end  112  along a flow path shown by arrow f 4  shown in  FIG. 11  in a generally downwardly direction. However, the direction of the flow may be altered by end fittings, aerators, spray heads, diverters and the like. 
     An important benefit of this embodiment of the invention wherein the bridge is a separate component from the valve assembly(ies) is that when not pre-assembled, a separate valve assembly structure can be fitted on either end of the bridge and the bridge can be aligned by rotatably positioning the spout receiving portion before being attached to the valve assembly so that the spout receiving portion of the bridge can be axially located and positioned at different angles to enable the spout to have a configuration that will fit within the interior space defined by the cover plate. For example, the spout tube may be designed to extend upwardly and curve downwardly near to the outlet end as shown in  FIG. 4 , or the spout tube may be shaped more like a U-shaped longer spout for a kitchen faucet, lower in height or taller in height and of a variety of shapes without requiring a whole separately molded assembly for each faucet water way assembly design configuration. 
     The invention can include a variety of spout tubes that work with varying configurations of the bridge. For example, the bridge  38  may include a spout receiving portion of various configurations for attachment of the spout tube, and also can be angled for combining with differing configurations of spout tubes by the rotatability of the bridge when forming the water way assembly from the bridge and valve assemblies. Thus, the spout receiving portion can rotate (in a multi-part bridge), or the entire bridge may rotate (in a single part bridge) when forming the assembly. Rotation occurs around the horizontal or transverse x-x axis through the bridge and water way assembly (shown best in  FIG. 9 ) so that the spout tube  40  when installed has a lower portion  103  that stems from the spout receiving portion, and the spout receiving portion  92  forms an angle γ of about 0° to about 90° between the z axis through the faucet and they axis or between the plane of the x-y axes, shown as plane P-P, and preferably an angle of about 30° to about 60° (see  FIG. 4 ). Thus, the spout receiving portion  92  of the bridge  38  can extend vertically upward along a vertical axis through the assembly (see embodiments  210 ,  310  discussed hereinbelow) or extend more toward the horizontal. As shown, the spout receiving portion extends outwardly at an angle with respect to plane P-P of the assembly after rotatably positioning the bridge in that position. However, it may be rotated anywhere between the straight up vertical position and the flat horizontal position before assembly. 
     When assembling the internal water way assembly, standard valve assemblies can thus be used to position vis-à-vis a bridge rotated so as to be in a preferred configuration for a particular design, and a spout tube (which may also include a variety of configurations for design purposes) can be attached. The cover plate is positioned over the assembly and attached thereto. The same bridge configuration and standard valve assemblies can work for a variety of faucet sizes and design configurations while forming only a small number of water way assembly internal faucet components. 
     The spout receiving portion may be molded as a portion of the bridge or in other embodiments of the invention having a multi-part bridge can be a separate intermediate piece. Thus, in such an embodiment, the bridge  38  may have multiple sections. An example is shown in the alternative embodiment of a faucet assembly  210  shown in  FIG. 14  as discussed further below. The bridge has a first valve water way section, an intermediate or spout receiving section and a second valve water way section. The intermediate spout receiving section can be rotated with respect to the first and second sections or with respect to the valve water way portion(s) of the valve assembly(ies) or both prior to assembly to position the spout tube. 
     Also in other embodiments, the spout receiving portion may incorporate an alternative or additional avenue for attaching the cover plate of the faucet assembly to the water way assembly. Taps or other holes may be provided, for example on the front and/or back of the central area of the bridge near the spout receiving portion (or on the spout receiving section of a multi-part bridge) so that fasteners such as self-tapping screws (or other fasteners mentioned herein) can pass through such taps or other holes in the central area or section of the bridge to be seated in mating bores within the cover plate thereby attaching the assembled internal water way to the cover plate via the central area or spout receiving section of the bridge. 
     By rotating the bridge (either the entire length thereof or a section(s) thereof in a multi-part assembly), the same valve assembly(ies) can act in a modular manner with varying bridges (and bridge sizes) having standard mating ends for the valve assemblies and a variety of spout tube configurations for a modular approach to internal water way assembly design so that the internal water way can be varied to conform and be assembled to work within a wide variety of outer design cover plates for varied faucet assembly products. However, the same valve assemblies can be formed for all of the different faucet designs. Further, standard bridge lengths and/or shapes can be developed so that the valve assembly and bridge combination fit within standard size faucet assembly base configurations. 
     There is no limit to the size, angle or creative configuration of the spout tube which can be interchanged with more standard sized bridges and valve assemblies. Such modular assembly is very cost effective for manufacture and reduces the number of and need for specialty assemblies while provide variability for creative design within preferred aesthetically pleasing outer cover plates. It also enables the manufacturer to use polymeric molding techniques in forming bridges, spout tubes and/or the valve assemblies or portions thereof which reduces overall cost of the faucet assemblies from those assemblies made primarily of metallic parts. 
     As noted above, in embodiment  10 , the internal water way assembly  14  is attached to the cover plate. The internal water way assembly may be permanently attached by any suitable means such as heat molding, ultrasonic or heat welding, soldering (in the case of metallic parts), use of pressure sensitive and/or heat sensitive adhesive materials and the like. In addition to such permanent bonding or as alternative thereto, the assembly may be releasably attached to the cover plate as shown in the preferred embodiment herein. 
     As shown, in the embodiment  10  of  FIGS. 1-13 , the internal water way assembly  14  is releasably attached to the cover plate  12 . Optional sealing agents or adhesives (or other bonding techniques noted above may also be used but are not necessary for completing the faucet assembly  10  herein. 
     In the faucet assembly of  FIGS. 1-13 , the assembly is releasably attached using fasteners as best shown with reference to  FIG. 3 . A fastener  118  is positioned within at least one outwardly extending tap  120  on the valve assembly having a hole  122  therein sized to receive the fastener  118 . The interior surface  22  of the cover plate  12  on either the top or bottom plate  18 ,  20  is formed so as to have at least one mating receiving bore  124  to receive the fastener once it passes through the hole  122  in the tap  120 . The fastener thus attaches the internal water way assembly  14  to the cover plate  12 . Preferably two or more such taps are provided to the valve assembly  36  for a stable and balanced connection and are preferably evenly tightened or snap-fit to the same degree on each portion of the assembly. Two taps are shown in the Figures on each valve assembly such that four fasteners are being used for two valve assemblies and there would be four mating bores on the interior surface of the cover plate. The fasteners  118  may be locking and mating fasteners, or the receiving bore and the fastener may be formed so as that the fastener is a self-tapping screw and the receiving bore is configured to receive the self-tapping screw. In addition, a threaded screw and a bore with mating screw threads may be used. Fasteners  32  are preferably self-tapping screws, however, the fastener(s) and receiving bore(s) may be varied and/or have other interlocking features. Other types of fasteners, including snap fit, dowels, pins, screws, and the like may be used if releasable attachment is desired. 
     More permanent attachment can also be achieved if desired by using tabs, but preferably without holes and adhering or molding the tabs to the interior surface on a similar piece within the interior surface of the cover plate. 
     Further, the configurations noted above may be reversed so that the fastener(s) are situated so as to fit into or be part of the cover plate and a screw such as a self-tapping screw may be formed onto the cover plate or received in a recess in the cover plate and the bore(s) may be located on the exterior of the valve water way portions instead of a tap(s) as shown. Finally, it is within the scope of the invention that the cover plate be formed so as to have an interior that snugly receives in features thereof at least the valve water way assembly portion(s) and/or the bridge so that the water way assembly snaps into mating features on the interior surface of the cover plate to hold the water way assembly in place. 
     Upon assembly and if desired, an optional putty plate  126  as is known in the art may be provided, and formed out of polymeric or metallic materials as noted herein. Such plate is not necessary for structural support and may be used simply for installation purposes as known in the art. 
     A further embodiment will now be described with respect to embodiment  210  of  FIGS. 14-23 , wherein analogous components have analogous reference numbers to components in embodiment  10  of  FIGS. 1-13 . The faucet shown is a kitchen faucet having a two-handle configuration, a multi-part cover plate and a multi-part bridge. Such a faucet may also be a single handle design, but is shown herein as a two-handle design for illustration purposes. In the faucet assembly, the cover plate  212  is a multi-part cover plate having a top spout plate  218  configured to cover a portion or all of a spout tube  240  and a bottom cover plate  220  configured to fit over the valve assembly  236  and bridge  238 . The cover plate  212  has an interior surface  222  and an exterior surface  224 , wherein the interior surface  222  defines an interior space  226  as shown. 
     The internal water way assembly  214  includes, as shown includes two valve assemblies  236  each having a shank  242  defining a longitudinally extending interior passageway therein  252 , and a valve water way portion  244  positioned on an upper portion  254  of the shank  242  and configured to define a valve seat therein. Such parts may be formed in the same manner and using the same materials as noted above. Valve cartridges  246  for controlling flow through the internal water way assembly  214  are provided, which may be the same as those valve cartridges described above. 
     The bridge  238  as shown in  FIGS. 15, 19-20 and 22-23  is a multi-part bridge having a passageway  296  therethrough in fluid communication with and to receive water from the outlet passageway  280  of the valve water way portion  244  of the valve assembly  236  and the bridge  238  has a spout receiving portion  292  having a passageway  294  therethrough. 
     The spout tube  240  has an inlet end  2104  configured to be positioned in the spout receiving portion  202  of the bridge  238 . The spout tube  240  is open at the inlet end  2104  and in fluid communication with the passageway  296  in the bridge  238 . The spout tube  240  has a second outlet end  2112  for delivering water out of the faucet assembly when in use. Two faucet handles  216  are positioned outside interior space  226  and are capable of operably moving the respective valve cartridges  246  for controlling the flow through the internal water way assembly. 
     As shown, the internal water way assembly  214  is attached to the cover plate  212  via the exemplary self-tapping screw fasteners  2118  on taps  2120  on each of the valve water way portions  244  valve assemblies  236 . It is also attached to the cover plate  212  by fasteners  2118 , which are shown as threaded screws but could be various types of fasteners as described elsewhere herein, on the spout receiving section  227  of the bridge  238 . 
     The spout receiving section  227  of the bridge  238  is designed so as to be rotatably positioned in an upright position to work with the upwardly positioned spout tube so that the angle γ as described above is 0°. The features on the spout receiving section  227  are accordingly provided to work in such a configuration in terms of attachment to the lower portion  220  of the cover plate  212 . The spout receiving portion  292  as shown is also configured to have an outlet portion that has threads  225  for mating with a fitting  233  for attaching the inlet end  2104  of the spout tube  240 . The fitting  233  is threaded internally and externally with external threads  235  configured to mate with threads  237  on an interior of a portion of the tube portion of the cover plate  218 . Thus, the fitting  233  screws over the top of the threads  225  on the spout receiving portion  292  and the screws  237  of the upper tube cover plate  218  screw onto the external threads  235  of the fitting  233  to tighten the cover plate portions together and the upper cover plate to the spout receiving portion. 
     While the spout receiving section  227  as shown is configured to be rotatably positioned so that the spout receiving portion  292  is directly upwardly oriented, it is within the scope of the invention that a spout receiving section can be formed that is readily rotated to be positioned at an angle with respect to the faucet plane P-P and the taps  2120  positioned at an alternative location or left off entirely on the spout receiving section. 
     The components may be configured using the same materials and combinations of materials as noted above with respect to faucet assembly  10 . In addition the internal water way  214  may be releasably or permanently attached to the cover plate  212 . As shown also in faucet assembly  210 , the valve assembly is unitarily formed as a separable component that can be attached permanently or releasably to the bridge  238 . 
     The spout tube  240  may be formed of the materials noted above as well and may have a portion that is cast metallic finish on a molded polymeric material so that the tube may be used directly without a separate outer portion if desired. 
     The valve cartridges  246  may be the same as those noted above with respect to the faucet assembly  10 , and may also extend upwardly through a valve cartridge openings  247  in the bottom cover plate  220  into the faucet handles  216 . 
     The multi-part bridge  238  includes two valve water way sections, a first valve water way section  229  and a second valve water way section  231  each having an inlet in communication with the transversely extending outlet passageways  280  of the valve water way portions  244  of the valve assemblies  236 . Each also has an outlet  241 . As noted above, a spout receiving section  227  is formed that incorporates the spout receiving portion  292  of the bridge  238 . The spout receiving portion also has an inlet  243 , and as shown has two such inlets, one for each outlet  241  of each of the valve water way sections  229 ,  231  of the bridge. When the valve water way sections  229 ,  231  are assembled with the spout receiving section  227 , the bridge passageway  296  extends through the valve water way sections  229 ,  231  and the spout receiving section  227 . The outlets  241  of the valve water way sections  229 ,  231  of the bridge  238  are each configured to engage the respective inlets  243  of the spout receiving section  227  of the bridge  238 . The outlets  241  and inlets  243  may be configured to fit together in mating attachment in a variety of ways as noted above with attachment of the ends  86   a ,  86   b  of the bridge  38  in faucet assembly  10  above. Thus, interlocking pieces, tabs, or, as shown flanges, etc. may be used. Preferably seals such as o-rings  245 . The interlocking of the bridge  238  to the valve water way portions  244  and of the valve water way sections  229 ,  231  to the spout receiving section  227  as well as any sealing engagement may be undertaken as described above with respect to the connection of bridge  38  to bridge receiving portions  82  of the valve water way portions  44  of the embodiment  10  shown in  FIGS. 1-15 , including but not limited to interlocking mating features, snap-fit features, locking tabs and slots, and bayonet lock connectors. 
     By preparing a multi-part bridge as shown, even further design standardization for additional automation of manufacture may be achieved in that the valve water way sections  229 ,  231  can be simply made in standard stock sizes for 4″, 8″ and other faucet sizes and platforms, while only the spout receiving section  227  is varied in design and/or rotatably positioned as well as variations if desired in spout tube and cover plate design. 
     While the faucet assembly  210  is shown with two valve assemblies and two valve water way sections on the multi-part bridge, it should be understood that a multi-part bridge can be provided with only a spout receiving section and single valve water way section for a single handle faucet having a hot and/or cold water mixer if desired within the scope of and without departing from the spirit of the present invention. 
     The spout receiving section  227  of the multi-part bridge  238  of kitchen faucet assembly  210  has an optional feature as shown including a lower outlet attachment feature  249 . Such an attachment may be used for attaching a separate fluid connection hose (not shown) for a spray head attachment or a separate hose to a quick-connection fitting for multiple inlet feed of fluid to the faucet assembly. Various quick-connection fittings are known in the art and may be used with the invention. One preferred embodiment of a quick-connection fitting is described and enclosed in U.S. Pat. No. 9,376,789 B2, incorporated herein by reference. 
     The invention also includes an embodiment as shown herein in the form of a lavatory faucet assembly  310 . The faucet assembly  310  has a bridge  338  which is not a multi-part bridge. The faucet assembly  310  is shown with a rapid installation drain assembly  351 . The drain assembly may be any suitable drain assembly, and such assemblies may be used with various embodiments of faucet assemblies herein. As shown, a drain assembly such as that described in U.S. Pat. No. 7,886,372 is used. The relevant portions of that patent are incorporated herein by reference to explain the manner in which such a drain assembly is made and used. A drain actuator and motion translation device are attached as assembly  253  to a recess  257  in the cover plate  312 . A drain assembly  255  connects to the assembly  253  when fully assembled and installed in and beneath a sink basin. 
     The bridge has inlet ends  386   a ,  386   b  and a passageway  396  therethrough so that flow through the passageway meets in the spout receiving portion  394  and passes upwardly through passageway  394  of the spout receiving portion. The bridge, as shown in  FIGS. 27 and 28  is angled in the x-y plane P-P between the x-x axis and the y-y axis at an angle β so as to create a slightly bent and curved backward angled bridge. The spout receiving portion  394  is at a 90° angle α between plane P-P and the z-axis. 
     Further, a flange  357  having fastener holes  359  therein is provided as an attachment to or formed with the spout receiving portion  392  of the bridge  338 . Fasteners can be provided to attach the flange and spout receiving portion to the cover plate. Further fasteners  357  may be provided through taps  3120  as well if desired for further attachment between the valve water way portions  344  and the cover plate in the manner described above with respect to embodiments  10  and  210 . The valve cartridges  346  may also be configured in a somewhat different manner than those of embodiments  10  and  210  to work with and fit within decorative handles  316 . 
     In all other respects, the faucet assembly  310  functions like the embodiment  10  and analogous features and reference numbers herein refer to analogous parts. 
     The invention also includes a method of assembling a faucet having an internal water way and will be described with respect to embodiment  10  of  FIGS. 1-15 . The method includes providing a cover plate  12  having an interior surface  22  defining an interior space  26 . Such cover plates may be as described above with respect to the various embodiments as well. An internal water way  14  is assembled. The water way preferably has at least one component comprising a polymeric material. The internal water way  14  is assembled by forming a valve assembly  36 , or in the case of a two-handle faucet, two valve assemblies  36 , each comprising a shank  42  defining a longitudinally extending interior passageway  52  therein. The valve assembly(ies) also include a valve water way portion  44  positioned on an upper portion  54  of the shank  52  and is configured to define a valve seat  62  therein. The valve water way portion(s)  44  each have a transversely extending outlet passageway  80  therein. The valve seat(s)  62  are configured to receive fluid from a fluid source. 
     A valve cartridge  46  is positioned in each valve seat  62 . The valve cartridges are for controlling flow and may be as described elsewhere herein. The cartridges have an inlet  76  for receiving water entering the valve seat  62  and an outlet  78  in communication with the outlet passageway  80  of the valve water way portion  44 . 
     A bridge  38  is provided according to the various embodiments herein and has a passageway  96  therethrough and a spout receiving portion  92  having a passageway  96  therethrough. 
     The bridge is rotatably positioned such that the spout receiving portion  92  is aligned to receive a spout tube  40  and the spout tube  40 , bridge  38  and valve assembly  36  will fit within the interior space of the cover plate upon assembly. 
     The bridge  38  is also attached to the valve water way portion  44  so that the passageway within the bridge  96  is in fluid communication with and able to receive water from the outlet passageway  80  of the valve water way portion  44  of the valve assembly  36 . The bridge may be attached and if not permanently attached rotated into position. Alternatively, the bridge is rotated to the desired position and then the valve water way portions attached thereto. If a multi-part bridge as in embodiment  210  is used, the spout receiving section is rotated to position and the bridge assembled by attaching the valve water way sections of the bridge and then attaching the valve water way portions to the valve water sections of the bridge. Alternatively, the valve water way sections can first be attached to the valve assembly valve water way portions and then the spout receiving section positioned and attached to the valve water way sections of the bridge. 
     The inlet end  104  of a spout tube  40  is attached to the spout receiving portion  92  of the bridge  38  to form an assembled internal water way. If a multi-part bridge is used, the spout receiving portion may be attached prior to completion of the bridge assembly if desired. Once assembled, the spout tube  40  is open at the inlet end  104  so as to be in fluid communication with the passageway  96  in the bridge  38  upon attachment and the spout tube  40  has a second outlet end  112  for delivering water out of the faucet assembly when in use. 
     The cover plate  12  is positioned over the assembled internal water way  14  and the interior surface  22  of the cover plate  12  is attached to the assembled internal water way  14 . The cover plate may be attached using a variety of fastener or interlocking techniques as noted above on either a spout receiving section on a multi-part bridge assembly, an area of the bridge near the spout receiving portion on a single part bridge or on one or more taps or similar structures on the valve water way portions of the valve assemblies as described herein above. 
     The faucet handle(s)  16  are then positioned on the valve cartridge(s)  46  so that the handle(s) is capable of operably moving the valve cartridge(s)  46  for controlling the flow through the assembled internal water way. 
     It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. It is understood, therefore, that this invention is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present invention as defined by the appended claims.
