CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims the benefit of, and priority to, U.S. Provisional Patent Application Ser. No. 63/142,814, filed on Jan. 28, 2021, the entire contents of which are incorporated by reference herein. 
    
    
     FIELD 
     The present disclosure relates to fluid sediment traps, in particular, untappable tamper-proof and anti-theft of service fluid sediment traps. 
     BACKGROUND 
     Gas-fired appliances, such as furnaces, heaters, boilers, and the like, require a gas supply line from the incoming gas supply to fuel the appliance. Connected to the gas lines is an extra leg of piping referred to as a sediment trap. Sediment traps are intentionally installed to prevent sediment, dirt, and/or particulates in the gas or piping, from entering the burner area of the appliance or associated components such as the gas ball valve connected upstream of the appliance. Specifically, a gas sediment trap uses gravity to capture sediment before it travels to the gas-fired appliance. Sediment traps are usually required at all gas appliances as part of the International Fuel Gas Code. The International Fuel Gas Code for the Sediment Trap section 408.4 (2015) states that when a sediment trap is not incorporated as part of the appliance, a sediment trap shall be installed downstream of the appliance shutoff valve as close to the inlet of the appliance as practical. Sediment traps are generally required by code on all furnaces, boilers, and water heaters in all states in the United States.

     Further details and aspects of various embodiments of the present disclosure are described in more detail below with reference to the appended figures. 
     DETAILED DESCRIPTION 
     This disclosure relates to fluid sediment traps, including non-tappable and anti-theft of service fluid sediment traps. The disclosed tamper-proof sediment trap solves the problem of theft of service caused by a user tapping (e.g., by using a tap and/or die to form threads) and/or disassembling a fluid sediment trap assembly (e.g., at the drip leg of the sediment trap assembly) and connecting another gas-fired appliance, effectively removing the sediment trap from the fluid circuit which can cause sediment to damage the gas-fired appliances and catastrophic appliance failure. As used herein, the term “fluid” includes gas and liquid and the terms “tap” or “thread” and variations thereof are intended to include any means by which two components can be joined together or which access can be made to join one component to another in a fluid circuit. 
     Although the present disclosure will be described in terms of specific embodiments, it will be readily apparent to those skilled in this art that various modifications, rearrangements, and substitutions may be made without departing from the spirit of the present disclosure. The scope of the present disclosure is defined by the claims appended hereto. 
     For purposes of promoting an understanding of the principles of the present disclosure, reference will now be made to exemplary embodiments illustrated in the drawings, and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the present disclosure is thereby intended. Any alterations and further modifications of the inventive features illustrated herein, and any additional applications of the principles of the present disclosure as illustrated herein, which would occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the present disclosure. 
     With reference to  FIG. 1 , a fluid circuit  100  is shown with an appliance  102  connected to a fluid source  120 . Generally, there are several methods for connecting the appliance  102  to the fluid source  120  in the fluid circuit  100 . 
     The fluid circuit  100  includes a shutoff valve  104  (e.g., a manual shutoff valve, ball valve, etc.) connected to an inlet  106  of the appliance  102 , downstream of the appliance  102 . The tamper-proof sediment trap  200  may be connected downstream of the shutoff valve  104 . Another shutoff valve  114  (e.g., a manual shutoff valve, ball valve, etc.) is included in the fluid circuit  100 , downstream of the tamper-proof sediment trap  200 . Fluid is supplied from the fluid source  120 , through the shutoff valve  114  to the tamper-proof sediment trap  200 , which is typically vertically mounted, to trap any sediment and debris present in the fluid. The fluid is then supplied to the appliance  102  via the tamper-proof sediment trap  200 , which traps sediment present in the supplied fluid, preventing delivery of the sediment in the fluid to the appliance  102 . Components, such as ball valves, hoses, fittings, pipe, etc., are certified for use with gas. Any type of connection can be used to couple the ends of tamper-proof sediment trap  200  to a fluid supply line  122  and to the appliance  102 . While different embodiments have shown threaded, compression, flare, National Pipe Thread (NPT), Male Iron Pipe (MIP), Female Iron Pipe (FIP), or other types of gas approved conventional connections, it is to be understood that any type of conventional connection that couples two or more components without creating a leak can be utilized. 
     Referring to  FIGS. 2A-2D , the tamper-proof sediment trap  200  of  FIG. 1  is shown and will now be described in detail. Tamper-proof sediment trap  200  includes a central body portion  210  defining a central longitudinal axis “L”, a supply leg portion  220 , an outlet leg portion  230 , and a drip leg portion  250 . The central body portion  210 , supply leg portion  220 , and outlet leg portion  230  are generally cylindrical in shape and cooperatively define (along with the drip leg portion  250 ) a lumen  202  configured to enable fluid to flow in from the supply leg portion  220 , through the central body portion  210 , and out from the outlet leg portion  230  (e.g., to a connected appliance), while trapping sediment in the drip leg portion  250 . The supply leg portion  220  is configured to couple to a fluid supply (e.g., fluid source  120  in  FIG. 1 ), the drip leg portion  250  is configured to trap sediment present in the fluid received from the fluid supply, and the outlet leg portion  230  is configured to deliver the sediment-free fluid to the appliance  102  ( FIG. 1 ). Sediment may include, but is not limited to, for example, shavings, threading compound, debris, dirt, and/or moisture. 
     An issue with existing fluid sediment trap assemblies made from multiple components coupled together (e.g., threaded together) is that the components can be separated to gain access to the fluid circuit (for example, the drip leg or the cap of the drip leg can be removed and refit with a threaded pipe) for theft of service, namely, to connect another, non-authorized, appliance to the fluid line. This has the dual effect of potentially overloading the fluid circuit with more appliances than the size (e.g., diameter) of the fluid lines are capable of handling and eliminating the sediment trapping function present in the fluid circuit. Without a sediment trap installed in the fluid circuit, sediment from the supplied fluid can enter the appliance, causing damage to, or even complete failure of, the appliance. Even a sediment trap that is formed of a single piece is prone to the same issues as the existing fluid sediment trap assemblies formed from multiple components, as a single piece sediment trap can still be threaded or tapped at is drip leg for theft of service. 
     The disclosed tamper-proof sediment trap  200  overcomes these issues by being monolithic, e.g., made of one single piece, and having a drip leg portion  250  possessing an outer profile or surface structure, or otherwise defining a shape, that is incapable of being tapped. As used in this disclosure, the term “monolithic” includes being made of one piece and or being integrally formed. Thus, the central body portion  210 , the outlet leg portion  230 , and the drip leg portion  250  are monolithically formed and are described herein as portions or sections of the tamper-proof sediment trap  200  which are non-separable from each other. The tamper-proof sediment trap  200  may be made out of any material or combination of materials that are typically used with and/or certified for use with fluid piping. This includes, for example, brass, forged brass, iron, steel, and other suitable materials. All of the portions of the tamper-proof sediment trap  200  may be formed of the same material, or alternatively, some portions may be formed of a first material while other portions are formed of a second, different material. 
     The outlet leg portion  230  extends upward from a side of the central body portion  210  parallel to the central longitudinal axis “L” of the central body portion  210  and defines an outlet  232  at its end. The outlet leg portion  230  is configured to be coupled to the appliance  102 . In aspects, the outlet  232  may include a national pipe thread (NPT) female thread and/or an NPT male thread. The NPT thread may be of any suitable diameter, for example, anywhere in the range of about ½″-6″. In an aspect, for example, the outlet leg portion  230  may include a FIP union for coupling to a pipe nipple. In another example, the outlet leg portion  230  may include a male flare union for coupling to a fluid hose with a flare connection. 
     The supply leg portion  220  extends radially outward from the central body portion  210 , at a point along the central longitudinal axis “L” of the central body portion  210  between the outlet leg portion  230  and the drip leg portion  250 , and has a central longitudinal axis “Lb” extending perpendicular to the central longitudinal axis “L” of the central body portion  210 . The supply leg portion  220  is configured to enable the flow of fluid from a fluid source  120  ( FIG. 1A ) to the central body portion  210  for enabling sediment to drop to the drip leg portion  250  while sediment-free fluid flows up through the outlet leg portion  230  to the connected appliance  102 . The supply leg portion  220  extends generally perpendicular to the length of the central body portion  210 , but may extend therefrom at any angle. In aspects, a proximal end  210   a  of the supply leg portion  220  may include an NPT female thread and or an NPT male thread. The NPT thread may be of any suitable diameter, for example, anywhere in the range of about ½″-6″. In an aspect, for example, the supply leg portion  220  may include a FIP union for coupling to a pipe nipple. In another example, the supply leg portion  220  may include a male flare union for coupling to a fluid hose with a flare connection. 
     Any of the central body portion  210 , the supply leg portion  220 , the outlet leg portion  230 , and/or the drip leg portion  250  may include an access tap  204  configured for connecting a small non-appliance tool or gauge or for clean-out access to the lumen  202  of the tamper-proof sediment trap  200 . The access tap  204  may define a raised flattened surface protruding from an outer surface of the central body portion  210 , or any portion of the tamper-proof sediment trap  200 , and may be centered at an intersection of the central longitudinal axis “Lb” of the supply leg portion  220  and the central longitudinal axis “L” of the central body portion  210 , but any position is contemplated. Additionally, although a single access tap  204  is illustrated and described, it is appreciated that any number of access taps may be included on the tamper-proof sediment trap  200 . The access tap  204  defines a threaded opening that may be dimensioned such that the size of the tap is limited to a size that can only be tapped, or otherwise accessed, by lines that are too small to fuel an appliance, but large enough to connect a small pressure gauge or blow-out line, for example, for purge and pressure-tap purposes. For example, the access tap  204  can be tapped to any suitably sized thread, for example, but not limited to ¼″, ⅛″, or ⅜″, or any size suitable for accessing the inner lumen  202  while not being large enough to connect a line to another appliance therefrom. In one aspect the access tap may be utilized to access the inside of drip leg portion  250  to clean-out sediment or other debris accumulated therein. The opening defined by the access tap  204  may be plugged by any suitable removable plug and/or may utilize a Pete&#39;s Plug® access plug. The utilization of a plug to close the opening of the access tap  204 , as opposed to a cap to close the opening of the access tap  204 , enables the connection and disconnection of a line to the access tap  204  without the need to pressure-test the integrity of the fluid circuit after the disconnection. 
     The various disclosed aspects of drip leg portion  250  of the tamper-proof sediment trap  200  will now be described in detail, in turn, as drip leg portion  2500  ( FIGS. 2A-2D ), drip leg portion  3500  ( FIGS. 3A-3D ), drip leg portion  4500  ( FIGS. 4A-4D ), drip leg portion  5500  ( FIGS. 5A-5D ), and drip leg portion  6500  ( FIGS. 6A-6C ). Each of drip leg portion  2500  ( FIGS. 2A-2D ), drip leg portion  3500  ( FIGS. 3A-3D ), drip leg portion  4500  ( FIGS. 4A-4D ), drip leg portion  5500  ( FIGS. 5A-5D ), and drip leg portion  6500  ( FIGS. 6A-6C ) are similar in scope, and possess similar structure and features except for the specific differences described below with respect to each. 
     With reference to  FIGS. 2A-2D , one aspect of the tamper-proof sediment trap  200  includes a drip leg portion  2500  defining an oblique conical frustum, having an offset inward taper. The drip leg portion  2500  extends downward from the central body portion  210 , is configured to collect sediment therein, and includes a proximal portion  2500   a  and a distal portion  2500   b . The proximal portion  2500   a  has a diameter “D” which is substantially equal to the diameter of the base from which it extends (e.g., from a distal portion of central body portion  210 ) and the distal portion  2500   b  has a diameter “d” being smaller than the diameter “D” of the proximal portion  2500   a , thereby defining the inward taper along its length. Although the proximal portion  2500   a  is illustrated as a circular base of the oblique conical shape, and is described as having a diameter “D”, it is contemplated that the base may be any shape, including a polygonal shape, forming one or more flat faces of the outer surface  2507  along the length of the drip leg portion  2500 . 
     A drip outlet  2502  is located at the distal portion  2500   b  of the drip leg portion  2500  and defines an opening configured for drainage and/or cleaning of the tamper-proof sediment trap  200 . The diameter “d” of the distal portion  2500   b  where the drip outlet  2502  is located, and thus, the size  2500   d  of the opening defined by the drip outlet  2502 , is small enough that an appliance cannot be connected to the tamper-proof sediment trap  200  from the opening of the drip outlet  2502 . A ratio may exist between the size  2500   d  of the opening and the size of the diameter of the supply leg portion  220  and/or the size of the diameter of the outlet leg portion  230 . The size  2500   d  of the opening may be based on the diameter of the supply leg portion  220  and/or the outlet leg portion  230 . In particular, the size  2500   d  of the opening may be larger (e.g., ⅜″) for tamper-proof sediment traps having larger diameter supply leg portions  220  and/or outlet leg portions  230  (e.g., 2″) and may be smaller (e.g., ⅛″) for tamper-proof sediment traps having smaller diameter supply leg portions  220  and/or outlet leg portions  230  (e.g., ¾″). The drip outlet  2502  defines an opening which may have a smooth or threaded inner surface, and may additionally or alternatively be threaded on its outer surface. The drip outlet  2502  may be plugged with a removable plug  2504  screwed into a female thread formed on an inner surface of the drip outlet  2502  within the opening defined by the drip outlet  2502 , or may be capped with a cap screwed onto a threaded outer surface of the drip outlet  2502 . The drip outlet  2502 , after removal of the removable plug  2504  or cap, is configured to enable access to an inside of the drip leg portion  2500  for removal of any sediment accumulated within the drip leg portion  2500 . The removable plug  2504  may be a Pete&#39;s Plug® access plug. In aspects, the drip outlet  2502  may have a male thread, and the removable plug  2504  may have a female thread and be externally mounted (e.g., a cap). The threaded inner or outer surface of the drip outlet  2502  may have a standard-directional thread or a reverse-directional thread configuration. In an aspect, the opening defined by the drip outlet  2502  is non-circular in shape. Additionally, with reference to  FIG. 2D , the inner surface of the distal portion  2500   b  of the drip leg portion  2500  may define an anti-stagnant feature  2520  which is bowl-shaped or otherwise tapers inwardly toward the drip outlet  2502  to direct all sediment toward the outlet thereby preventing the build-up of sediment which would be difficult to remove during clean-out of the interior of the drip leg portion  2500 . 
     The drip leg portion  2500  may define a length being long enough to prevent a vortex from sucking sediment back up from the drip leg portion  2500  to other portions of the tamper-proof sediment trap  200  such as the central body portion  210  and the outlet leg portion  230  and eventually enter into to an appliance  102  ( FIG. 1 ). In aspects, the drip leg portion  2500  is at least about 3 inches long. In aspects, the thickness of the walls of the drip leg portion  2500  is greater than the thickness of the walls of the other portions of the tamper-proof sediment trap  200  such as the central body portion  210 , the supply leg portion  220 , and/or the outlet leg portion  230  to further prevent the ability to tap, or otherwise couple to, the drip leg portion  2500 . Additionally, or alternatively, the material forming the drip leg portion  2500  may possess a greater strength or hardness than that of the other portions of the tamper-proof sediment trap  200  such as the central body portion  210 , the supply leg portion  220 , and/or the outlet leg portion  230  to further prevent the ability to tap, thread, or otherwise couple to, the drip leg portion  2500 . 
     The drip leg portion  2500  defines an oblique conical shape that makes it difficult, if not impossible, to tap. As shown in  FIGS. 2A-2D , the drip leg portion  2500  has an offset taper. The taper of the drip leg portion  2500  begins close enough to the central body portion  210  such that the drip leg portion  2500  cannot be cut off or otherwise removed to thread or tap the remaining portions of the drip leg portion  2500  or portions of the central body portion  210 . In other words, the proximal-most end of the proximal portion  2500   a  of the drip leg portion  2500  begins proximate the point along the central longitudinal axis “L” where the supply leg portion  220  extends radially outward and may be spaced therefrom a maximum distance “H” ( FIG. 2B ) to prevent the possibility of the formation of a vortex or siphon upward towards the outlet leg portion  230 , thereby ensuring that all sediment drops into the drip leg portion  2500 . 
     With continued reference to  FIGS. 2A-2D , the oblique conical shape defined by the drip leg portion  2500  forms an outer profile  2506  which thwarts the ability to tap or thread the outer surface  2507  of the drip leg portion  2500 . As described above, drip leg portion  2500  is generally shaped as an oblique circular cone or frustum, where its axis passes through the base non-perpendicularly, with at least one side tapering smoothly inward towards the drip outlet  2502  (when viewed from a side perspective). In particular, the apex  2510  of the cone or frustum of the drip leg portion  2500  is not centered over the base of the drip leg portion  2500 . With such a configuration, the position of the drip outlet  2502  is offset from the central longitudinal axis “L” of the central body portion  210 . 
     With particular reference to  FIG. 2D , portions of the inner surface  2508  of the drip leg portion  2500  may be smooth or textured to modify the flow properties of fluid within the drip leg portion  2500  and to further inhibit the ability to tap the inner surface  2508  of drip leg portion  2500 . Additionally or alternatively, with continued reference to  FIG. 2D , when viewed from a side perspective, at least one side of the drip leg portion  2500  may be straight, that is, at least one side may extend linearly downward with no taper toward the drip outlet  2502 . In one embodiment, the straight side of the drip leg portion  2500  extends downward from a side of the central body portion  210  that is opposite the side of the central body portion from which the supply leg portion  220  extends such that as fluid enters the tamper-proof sediment trap  200  from the supply leg portion  220 , the fluid and sediment therein hits the straight wall of the interior of the central body portion  210  which continuous to the straight wall of the drip leg portion  2500 . 
     With reference to  FIGS. 3A-3D , another aspect of the tamper-proof sediment trap  200  includes a drip leg portion  3500  defining a generally conical shape, that is, of a right circular cone or frustum. The drip leg portion  3500  is similar to the drip leg portion  2500 , and the other drip leg portions described herein, and therefore only the differences therebetween will be described in detail. The drip leg portion  3500  extends downward from the central body portion  210  tapering inward, is configured to collect sediment therein, and includes a proximal portion  3500   a  and a distal portion  3500   b . The proximal portion  3500   a  has a diameter “D” which is substantially equal to the diameter of the base from which it extends (e.g., from a distal portion of central body portion  210 ) and the distal portion  3500   b  has a diameter “d” being smaller than the diameter “D” of the proximal portion  3500   a , thereby defining the inward taper along its length. Although the proximal portion  3500   a  is illustrated as a circular base of the conical shape, and is described as having a diameter “D”, it is contemplated that the base may be any shape, including a polygonal shape, forming one or more flat faces of the outer surface  3507  along the length of the drip leg portion  3500 . 
     A drip outlet  3502  is located at the distal portion  3500   b  of the drip leg portion  3500  and defines an opening configured for drainage and/or cleaning of the tamper-proof sediment trap  200 . The diameter “d” of the distal portion  3500   b  where the drip outlet  3502  is located, and thus, the size  3500   d  of the opening defined by the drip outlet  3502 , is small enough that an appliance cannot be connected to the tamper-proof sediment trap  200  from the opening of the drip outlet  3502 . A ratio may exist between the size  3500   d  of the opening and the size of the diameter of the supply leg portion  220  and/or the size of the diameter of the outlet leg portion  230 . The size  3500   d  of the opening may be based on the diameter of the supply leg portion  220  and/or the outlet leg portion  230 . In particular, the size  3500   d  of the opening may be larger (e.g., ⅜″) for tamper-proof sediment traps having larger diameter supply leg portions  220  and/or outlet leg portions  230  (e.g., 2″) and may be smaller (e.g., ⅛″) for tamper-proof sediment traps having smaller diameter supply leg portions  220  and/or outlet leg portions  230  (e.g., ¾″). The drip outlet  3502  defines an opening which may have a smooth or threaded inner surface, and may additionally or alternatively be threated on its outer surface. The drip outlet  3502  may be plugged with a removable plug  3504  screwed into a female thread formed on an inner surface of the drip outlet  3502  within the opening defined by the drip outlet  3502 , or screwed onto a threaded outer surface of the drip outlet  3502 . The drip outlet  3502 , after removal of the removable plug  3504 , is configured to enable access to an inside of the drip leg portion  3500  for removal of any sediment accumulated within the drip leg portion  3500 . In aspects, the drip outlet  3502  may have a male thread, and the removable plug  3504  may have a female thread and be externally mounted (e.g., a cap). The threaded inner or outer surface of the drip outlet  3502  may have a standard-directional thread or a reverse-directional thread configuration. In an aspect, the opening defined by the drip outlet  3502  is non-circular in shape. Additionally, with reference to  FIG. 3D , the inner surface of the distal portion  3500   b  of the drip leg portion  3500  may define an anti-stagnant feature  3520  which is bowl-shaped or otherwise tapers inwardly toward the drip outlet  3502  to direct all sediment toward the outlet thereby preventing the build-up of sediment which would be difficult to remove during clean-out of the interior of the drip leg portion  3500 . 
     The drip leg portion  3500  may define a length being long enough to prevent a vortex from sucking sediment back up from the drip leg portion  3500  to other portions of the tamper-proof sediment trap  200  such as the central body portion  210  and the outlet leg portion  230  and eventually enter into to an appliance  102  ( FIG. 1 ). In aspects, the drip leg portion  3500  is at least about 3 inches long. In aspects, the thickness of the walls of the drip leg portion  3500  is greater than the thickness of the walls of the other portions of the tamper-proof sediment trap  200  such as the central body portion  210 , the supply leg portion  220 , and/or the outlet leg portion  230  to further prevent the ability to tap, or otherwise couple to, the drip leg portion  3500 . Additionally, or alternatively, the material forming the drip leg portion  3500  may possess a greater strength or hardness than that of the other portions of the tamper-proof sediment trap  200  such as the central body portion  210 , the supply leg portion  220 , and/or the outlet leg portion  230  to further prevent the ability to tap, thread, or otherwise couple to, the drip leg portion  3500 . 
     The drip leg portion  3500  defines a conical shape that makes it difficult, if not impossible, to tap. As shown in  FIGS. 3A-3D , the drip leg portion  3500  has a consistent taper where the drip outlet  3502  is centrally aligned with the central longitudinal axis “L” of the central body portion  210 , but a non-consistent taper is also contemplated. The taper of the drip leg portion  3500  begins close enough to the central body portion  210  such that the drip leg portion  3500  cannot be cut off or otherwise removed to thread or tap the remaining portions of the drip leg portion  3500  or portions of the central body portion  210 . In other words, the proximal-most end of the proximal portion  3500   a  of the drip leg portion  3500  begins proximate the point along the central longitudinal axis “L” where the supply leg portion  220  extends radially outward and may be spaced therefrom a maximum distance to prevent the possibility of the formation of a vortex or siphon upward towards the outlet leg portion  230 , thereby ensuring that all sediment drops into the drip leg portion  3500 . 
     With continued reference to  FIGS. 3A-3D , the conical shape defined by the drip leg portion  3500  forms an outer profile  3506  which thwarts the ability to tap or thread the outer surface  3507  of the drip leg portion  3500 . As described above, drip leg portion  3500  is generally shaped as a cone, where its axis passes through the base perpendicularly, with sides tapering smoothly towards the drip outlet  3502 . With such a configuration, the position of the drip outlet  3502  is aligned with the central longitudinal axis “L” of the central body portion  210 . With particular reference to  FIG. 3D , portions of the inner surface  3508  of the drip leg portion  3500  may be smooth or textured to modify the flow properties of fluid within the drip leg portion  3500  and to further inhibit the ability to tap the inner surface  3508  of drip leg portion  3500 . 
     With reference to  FIGS. 4A-4D , another aspect of the tamper-proof sediment trap  200  includes a drip leg portion  4500  defining a generally conical shape with an inward taper, that is, of a right circular cone while having a spiral outer surface texture. The drip leg portion  4500  extends downward from the central body portion  210 , is configured to collect sediment therein, and includes a proximal portion  4500   a  and a distal portion  4500   b . The proximal portion  4500   a  has a diameter “D” which is substantially equal to the diameter of the base from which it extends (e.g., from a distal portion of central body portion  210 ) and the distal portion  4500   b  has a diameter “d” being smaller than the diameter “D” of the proximal portion  3500   a , thereby defining the inward taper. Although the proximal portion  4500   a  is illustrated as a circular base of the conical shape, and is described as having a diameter “D”, it is contemplated that the base may be any shape, including a polygonal shape, forming one or more flat faces of the outer surface  4507  along the length of the drip leg portion  4500 . 
     A drip outlet  4502  is located at the distal portion  4500   b  of the drip leg portion  4500  and defines an opening configured for drainage and/or cleaning of the tamper-proof sediment trap  200 . The diameter “d” of the distal portion  4500   b  where the drip outlet  4502  is located, and thus, the size  4500   d  of the opening defined by the drip outlet  4502 , is small enough that an appliance cannot be connected to the tamper-proof sediment trap  200  from the opening of the drip outlet  4502 . A ratio may exist between the size  4500   d  of the opening and the size of the diameter of the supply leg portion  220  and/or the size of the diameter of the outlet leg portion  230 . The size  4500   d  of the opening may be based on the diameter of the supply leg portion  220  and/or the outlet leg portion  230 . In particular, the size  4500   d  of the opening may be larger (e.g., ⅜″) for tamper-proof sediment traps having larger diameter supply leg portions  220  and/or outlet leg portions  230  (e.g., 2″) and may be smaller (e.g., ⅛″) for tamper-proof sediment traps having smaller diameter supply leg portions  220  and/or outlet leg portions  230  (e.g., ¾″). The drip outlet  4502  defines an opening which may have a smooth or threaded inner surface, and may additionally or alternatively be threated on its outer surface. The drip outlet  4502  may be plugged with a removable plug  4504  screwed into a female thread formed on an inner surface of the drip outlet  4502  within the opening defined by the drip outlet  4502 , or screwed onto a threaded outer surface of the drip outlet  4502 . The drip outlet  4502 , after removal of the removable plug  4504 , is configured to enable access to an inside of the drip leg portion  4500  for removal of any sediment accumulated within the drip leg portion  4500 . In aspects, the drip outlet  4502  may have a male thread, and the removable plug  4504  may have a female thread and be externally mounted (e.g., a cap). The threaded inner or outer surface of the drip outlet  4502  may have a standard-directional thread or a reverse-directional thread configuration. In an aspect, the opening defined by the drip outlet  4502  is non-circular in shape. Additionally, with reference to  FIG. 4D , the inner surface of the distal portion  4500   b  of the drip leg portion  4500  may define an anti-stagnant feature  4520  which is bowl-shaped or otherwise tapers inwardly toward the drip outlet  4502  to direct all sediment toward the outlet thereby preventing the build-up of sediment which would be difficult to remove during clean-out of the interior of the drip leg portion  4500 . 
     The drip leg portion  4500  may define a length being long enough to prevent a vortex from sucking sediment back up from the drip leg portion  4500  to other portions of the tamper-proof sediment trap  200  such as the central body portion  210  and the outlet leg portion  230  and eventually enter into to an appliance  102  ( FIG. 1 ). In aspects, the drip leg portion  4500  is at least about 3 inches long. In aspects, the thickness of the walls of the drip leg portion  4500  is greater than the thickness of the walls of the other portions of the tamper-proof sediment trap  200  such as the central body portion  210 , the supply leg portion  220 , and/or the outlet leg portion  230  to further prevent the ability to tap, or otherwise couple to, the drip leg portion  4500 . Additionally, or alternatively, the material forming the drip leg portion  4500  may possess a greater strength or hardness than that of the other portions of the tamper-proof sediment trap  200  such as the central body portion  210 , the supply leg portion  220 , and/or the outlet leg portion  230  to further prevent the ability to tap, thread, or otherwise couple to, the drip leg portion  4500 . 
     The drip leg portion  4500  defines a conical shape that makes it difficult, if not impossible, to tap. As shown in  FIGS. 4A-4D , the drip leg portion  4500  has a consistent taper where the drip outlet  4502  is centrally aligned with the central longitudinal axis “L” of the central body portion  210 , but a non-consistent taper is also contemplated. The taper of the drip leg portion  4500  begins close enough to the central body portion  210  such that the drip leg portion  4500  cannot be cut off or otherwise removed to thread or tap the remaining portions of the drip leg portion  4500  or portions of the central body portion  210 . In other words, the proximal-most end of the proximal portion  4500   a  of the drip leg portion  4500  begins proximate the point along the central longitudinal axis “L” where the supply leg portion  220  extends radially outward. 
     With continued reference to  FIGS. 4A-4D , the conical shape and spiraled outer surface  4507  defined by the drip leg portion  4500  forms an outer profile  4506  which thwarts the ability to tap or thread the outer surface  4507  of the drip leg portion  4500 . As described above, drip leg portion  4500  is generally shaped as a cone, where its axis passes through the base perpendicularly, with sides tapering towards the drip outlet  4502 . The drip leg portion  4500  is generally shaped as a spiral of increasingly smaller discrete diameters tapering towards the drip outlet  4502 . Although described as a consistent spiral, a step-down configuration is also contemplated. In aspects, the inner surface  4508  of the drip leg portion  4500  may have a smooth taper towards the drip outlet  4502  or a stepped (e.g., spiral) surface to match the outer surface  4507  profile. With such a configuration, the position of the drip outlet  4502  is aligned with the central longitudinal axis “L” of the central body portion  210 . With particular reference to  FIG. 4D , portions of the inner surface  4508  of the drip leg portion  4500  may be smooth or textured to modify the flow properties of fluid within the drip leg portion  4500  and to further inhibit the ability to tap the inner surface  4508  of drip leg portion  4500 . 
     With reference to  FIGS. 5A-5D , another aspect of the tamper-proof sediment trap  200  includes a drip leg portion  5500  defining a reverse conical shape, that is, of a right circular cone tapering outwardly forming a tamper-proof sediment trap  200  with an increased interior volume  5500   v , which may be beneficial for larger applications, and optional reduced overall length enabled by the increased interior volume  5500   v  which may be useful for tightly-spaced applications. The drip leg portion  5500  extends downward from the central body portion  210 , is configured to collect sediment therein, and includes a proximal portion  5500   a  and a distal portion  5500   b . The proximal portion  5500   a  has a diameter “D” which is substantially equal to the diameter of the base from which it extends and the distal portion  5500   b  has a diameter “d” being larger than the diameter “D” of the proximal portion  5500   a , thereby defining the outward taper. In an aspect, the diameter “d” is dimensioned such that it does not exceed the distance from which the supply leg portion  220  extends from the central body portion  210 . Although the proximal portion  5500   a  is illustrated as circular, and is described as having a diameter “D”, it is contemplated that the proximal portion  5500   a  may be any shape, including a polygonal shape, forming one or more flat faces of the outer surface  5507  along the length of the drip leg portion  5500 . 
     A drip outlet  5502  is located at the distal portion  5500   b  of the drip leg portion  5500  and defines an opening configured for drainage and/or cleaning of the tamper-proof sediment trap  200 . The drip outlet  5502  defines an opening which may have a smooth or threaded inner surface, and may additionally or alternatively be threated on its outer surface. The drip outlet  5502  may be plugged with a removable plug  5504  screwed into a female thread formed on an inner surface of the drip outlet  5502  within the opening defined by the drip outlet  5502 , or screwed onto a threaded outer surface of the drip outlet  5502 . The drip outlet  5502 , after removal of the removable plug  5504 , is configured to enable access to an inside of the drip leg portion  5500  for removal of any sediment accumulated within the drip leg portion  5500 . In aspects, the drip outlet  5502  may have a male thread, and the removable plug  5504  may have a female thread and be externally mounted (e.g., a cap). In an aspect, the opening defined by the drip outlet  5502  is non-circular in shape. Additionally, with reference to  FIG. 5D , the inner surface of the distal portion  5500   b  of the drip leg portion  5500  may define an anti-stagnant feature  5520  which is bowl-shaped or otherwise tapers inwardly toward the drip outlet  5502  to direct all sediment toward the outlet thereby preventing the build-up of sediment which would be difficult to remove during clean-out of the interior of the drip leg portion  5000 . 
     The drip leg portion  5500  may define a length being long enough to prevent a vortex from sucking sediment back up from the drip leg portion  5500  to other portions of the tamper-proof sediment trap  200  such as the central body portion  210  and the outlet leg portion  230  and eventually enter into to an appliance  102  ( FIG. 1 ). In aspects, the drip leg portion  5500  is at least about 3 inches long, but a reduced length is contemplated given the increased interior volume  5500   v  formed by the outward flare of the sides. In aspects, the thickness of the walls of the drip leg portion  5500  is greater than the thickness of the walls of the other portions of the tamper-proof sediment trap  200  such as the central body portion  210 , the supply leg portion  220 , and/or the outlet leg portion  230  to further prevent the ability to tap, or otherwise couple to, the drip leg portion  5500 . Additionally, or alternatively, the material forming the drip leg portion  5500  may possess a greater strength or hardness than that of the other portions of the tamper-proof sediment trap  200  such as the central body portion  210 , the supply leg portion  220 , and/or the outlet leg portion  230  to further prevent the ability to tap, thread, or otherwise couple to, the drip leg portion  5500 . 
     The drip leg portion  5500  defines an outwardly tapering conical shape that makes it difficult, if not impossible, to tap, reduces the length of the drip leg portion  5500  and the tamper-proof sediment trap  200  as a whole, and increased the interior volume  5500   v  of the drip leg portion  5500 . As shown in  FIGS. 5A-5D , the drip leg portion  5500  has a consistent taper where the drip outlet  5502  is centrally aligned with the central longitudinal axis “L” of the central body portion  210 , but a non-consistent taper is also contemplated. The outward taper of the drip leg portion  5500  begins close enough to the central body portion  210  such that the drip leg portion  5500  cannot be cut off or otherwise removed to thread or tap the remaining portions of the drip leg portion  5500  or portions of the central body portion  210 . In other words, the proximal-most end of the proximal portion  5500   a  of the drip leg portion  5500  begins proximate the point along the central longitudinal axis “L” where the supply leg portion  220  extends radially outward. 
     With continued reference to  FIGS. 5A-5D , the reverse conical shape defined by the drip leg portion  5500  forms an outer profile  5506  which thwarts the ability to tap or thread the outer surface  5507  of the drip leg portion  5500  and enables a shortened length of the tamper-proof sediment trap  200  useful for tightly-spaced applications. As described above, drip leg portion  5500  is generally shaped as a reverse cone, where its axis passes through the base perpendicularly, with sides tapering outward smoothly away from the drip outlet  5502 . With such a configuration, the position of the drip outlet  5502  is aligned with the central longitudinal axis “L” of the central body portion  210 . With particular reference to  FIG. 5D , portions of the inner surface  5508  of the drip leg portion  5500  may be smooth or textured to modify the flow properties of fluid within the drip leg portion  5500  and to further inhibit the ability to tap the inner surface  5508  of drip leg portion  5500 . 
     With reference to  FIGS. 6A-6C , another aspect of the tamper-proof sediment trap  200  includes a drip leg portion  6500  defining a generally bowled lower portion forming an even further reduced-length tamper-proof sediment trap  200  useful for tightly-spaced applications, while forming an increased interior volume  6500   v . The drip leg portion  6500  extends downward from the central body portion  210  and is wide enough that it also extends downward from the supply leg portion  220 . Thus, the width of the drip leg portion  6500  is substantially equal to the distance between one edge of the central body portion and a point along the length of the supply leg portion  220 . Although defining a reduced length, the interior volume of the drip leg portion  6500  is substantially equal to the interior volume of a 3″ diameter pipe having a length greater than the length of the drip leg portion  6500 . 
     Any of the above-described tamper-proof sediment traps  200  may include a floating/sliding plug configured to unplug the opening when the level of fluid within the drip leg portion exceeds a predetermined level. Additionally, or alternatively, any of the above-described tamper-proof sediment traps  200  may include a sensor (e.g., a fluid sensor) positioned such that an alarm is triggered when the level of fluid within the drip leg portion exceeds a predetermined level.
