     BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to an apparatus for automatically dispensing liquid chemicals into a toilet bowl from a remote liquid reservoir. 
     Background 
     Chemical treatments are known to be useful in keeping toilet bowls clean and sanitary. Some of the earliest systems designed are still in use today, consisting of tablets or blocks of cleaning agent that are placed inside the water tank. Over time the cleaning agent dissolves into the water inside the water tank such that when the toilet is flushed the cleaning agent is supplied to the toilet bowl. Other systems use concentrated liquid sanitizing chemicals with dispensers that hang on the side of the toilet tank or sit on the bottom of the water tank where their float operated mechanisms release a small amount of concentrated sanitizing liquid into the water tank water as the tank is refilling. These liquid systems also supply the sanitizing chemicals to the bowl when flushed. Chemicals that are mixed with the flush water in the water tank have the disadvantage that much of the chemicals are wasted when they pass through the toilet bowl during flushing; only a small portion of the flush water remains in the toilet bowl at the end of the flush. The small quantity of chemicals and flush water remaining in the bowl is then diluted with fresh water that flows into the bowl to restore the water seal. Another drawback to adding cleaning and sanitizing agents both solids and liquids to the water tank is that certain chemicals contained in the cleaning agents have an adverse effect on the rubber and metallic components inside the water tank. Over time the constant attack by the chemicals of the sanitizing or cleaning agents will cause some components to fail or leak requiring their replacement. A less wasteful and more desirable method developed is to add cleaning chemicals for treating a toilet bowl directly into the bowl. An effective way to perform this is by delivering the chemicals into the overflow pipe located inside the water tank where they will flow down the overflow pipe around the flush valve and into the bowl. Adding the chemicals to the overflow pipe keeps them from contacting and adversely degrading the metal and rubber components located inside the water tank. Adding chemicals to the overflow pipe also minimizes the quantity of chemicals needed as the chemicals are added during the time the bowl is refilling with fresh water, after the flush water has already passed out of the bowl and into the sewer. Adding chemicals to the refill water that refills the bowl after each flush allows the chemicals to be mixed and delivered to the bowl where they will stay in the bowl sanitizing and cleaning the bowl until the next flush. Systems designed to suction a liquid chemical out of a reservoir located inside the water tank but isolated from the water within are restricted to a relatively small volume and require the user to frequently lift the heavy and fragile water tank lid to replenish the chemicals in the reservoir. To reduce the frequency of replenishing the liquid in a liquid only reservoir, other systems have been developed that use concentrated solid or granular chemicals that are mixed with water, by allowing the water to flow over such solid chemicals or by allowing the solids to soak in a bath of water they create a sort of liquid chemical tea. 
     During subsequent flushes refill water flows over the solids and washes the chemical tea into the overflow pipe. Still other systems modified the way the solids are positioned, some partially in the water bath and sprayed with refill water, some have sump systems with weak suctioning devices to pull the chemical tea into the flow of refill water that passes into the overflow pipe. These solid chemical type systems have a drawback in that the most concentrated liquid chemical solution is what is sitting in the reservoir when the flush cycle just starts; this concentrated solution is drawn out of or flushed out of the chemical dispenser when the refill water just starts to flow. The most concentrated liquid cleaning and sanitizing agent then flows into the bowl before the initial flush water has fully stopped flowing out of the bowl causing it to flow past the bowl where it is lost to the sewer. The solid chemical type systems have another drawback as they do not provide a consistent dose of chemicals with each flush. If a solid or granular chemical is left to soften in the water tank or a container hanging inside the water tank for a long period of time such as overnight or for a long weekend, the moist and wet condition inside the water tank and chemical container located inside of the water tank will allow a large quantity of chemical substance to be released. If however the toilet is flushed more than once within a short time interval much less of the chemical will have had a chance to be softened and be released to clean or sanitize the toilet bowl. Adding chemicals from a liquid reservoir that is isolated from the water in the water tank provides a consistent quantity of chemicals with each flush regardless of how long it has been since the prior flush. Chemical treatments that are placed inside the water tank require the user to frequently lift the heavy and often fragile water tank lid to replace or replenish the chemicals. There are chemical additive systems that require the user to pour chemicals from one container to another in order to replenish the reservoir creating a hazard to the user. Some toilet bowl cleaning systems require the user to open or close a valve to enable the cleaning system. A more effective way would be to allow the chemical additive system to operate with no user intervention with each and every flush. Still other systems have complicated mechanical levers, rotating cylinders or other moving parts that reduce the reliability of such systems. Ideally the chemical injection system should have few or no moving parts that will eventually fail. 
     BRIEF SUMMARY OF THE INVENTION 
     A Liquid chemical dispensing apparatus for toilet bowls with remote liquid reservoir that automatically adds liquid cleaning and sanitizing chemicals directly into the toilet bowl of a flush toilet having; a water tank, a bowl, a ballcock refill valve, an overflow pipe and a refill tube that is connected between the ballcock refill valve outlet and the top of the overflow pipe. Said Liquid chemical dispensing apparatus for toilet bowls with remote liquid reservoir having a support assembly that hangs on the top edge of the water tank to support and protect a chemical transport tube as it passes into the water tank from outside the water tank. A three port eductor assembly that is located inside said water tank. The first port, an inlet port with an internal nozzle is connected by a flexible tube to the ballcock refill valve outlet, the nozzle generating a high velocity flow of water through the eductor assembly while the ballcock refill valve is open. The second port, a discharge port is connected by a second tube to the top of the overflow pipe where the exiting refill water flows into the overflow pipe. In operation the high velocity flow of water exiting the nozzle creates an area of low pressure or suction near the nozzle discharge internal to the eductor assembly. The third port an eductor suction port is common to and fluidly connected to the area where the suction is generated. The suction produced in the eductor suction port draws in liquid chemicals through the chemical transport tube attached to and fluidly connected between the eductor suction port and a dip tube that extends to the bottom most region of the remote liquid reservoir. Refill water along with liquid chemicals drawn into the eductor suction port from the remote liquid reservoir are mixed in the eductor assembly and then flow out through the eductor discharge port. A first end of a discharge tube is connected to the eductor discharge port. Internal to the discharge tube close to the first end is a flood ring that causes the eductor assembly to flood with liquid which enhances the vacuum produced in the eductor assembly. The second end of the discharge tube is attached to the overflow pipe so the discharge is directed into the overflow pipe. Once inside the overflow pipe the chemically treated water flows by gravity into the bowl where it restores the water seal and treats all surfaces contacted. The eductor assembly has a flow control device that limits the quantity of chemicals added through the eductor suction port during each toilet bowl refill cycle to regulate the resulting chemical concentration in the toilet bowl. The remote liquid reservoir is located external to the water tank and below the full water level in the water tank. In a preferred embodiment the remote liquid reservoir is a readily available manufactures standard sized household container of cleaning or sanitizing chemical such as a 121 oz or 1 gallon bleach container set on the floor next to the toilet, the remote liquid reservoir being secured inside another enclosure to prevent small children and pets from contacting the chemicals stored inside and to hide the remote liquid reservoir from view. The eductor assembly is located above the level of the overflow pipe and the eductor suction port is located on the upper surface of eductor assembly such that when the ballcock refill valve closes, the tubing attached between the ballcock refill valve, the eductor assembly and the overflow pipe will empty of water creating a siphon break and prevent water from flowing backwards through the chemical transport tubing into the remote liquid reservoir.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring now to the drawings wherein the showings are for purposes of illustrating various aspects of the invention and not for purposes of limiting the same. 
     Proceeding therefore to describe the invention in detail, reference should first be made to  FIG. 1  which shows a typical toilet  10  having a bowl  24  and a water tank  25 . Flushing is accomplished when a person pushes down on flush lever  9  which causes flush valve  11  to pivot open and allow water in the water tank  25  to pass out through the flush valve  11  into the bowl  24 . The water level quickly drops from a maximum level to a minimum level and the flush valve  11  closes. A ballcock  12  includes a float  13  which drops when the water level drops and allows water from a main water supply valve  26  to pass out of a main flow outlet  27  into the water tank  25  to refill it. Refilling continues until its maximum level is reached where the float  13  has risen far enough to move lever  28  to close a ballcock valve  14  stopping the outward water flow. During the entire time that main flushing water passes out of the main flow outlet  27 , a smaller amount of water passes out of a ballcock refill valve outlet  15  and passes through a tube that is not shown to the top of the overflow pipe  16 . Water flowing down the overflow pipe  16  passes around the flush valve  11  and flows directly into the toilet bowl  24  to refill it and restore the liquid seal in the bottom of the bowl  24  as almost all the water passing out of the flush valve  11  passes through the toilet bowl  24  and into the sewer to flush out waste leaving only a small portion remaining in the toilet bowl  24 . 
     Still referring to  FIG. 1 , the standard water flushing equipment of the particular toilet  10  is shown with a first preferred embodiment of the liquid chemical dispensing apparatus for toilet bowls with remote liquid reservoir. In this particular embodiment a remote liquid reservoir  21  is located external to the water tank  25  at a point where the top of the remote liquid reservoir  21  is below the level plane that passes through the top of the overflow pipe  16 . The remote liquid reservoir  21  shown is a manufactures standard household sized container of liquid bleach that is easily and inexpensively replaced without having to pour chemicals from one container to another. Use of a bleach container is optional the chemical container and chemical that is placed inside the remote liquid reservoir  21  may be another cleaning, sanitizing, deodorizing, surfactant or oxidizing product in a liquid state. In the particular embodiment shown in  FIG. 1  the remote liquid reservoir  21  has a Cap  42  ( FIG. 7 ) with an opening that a semi stiff plastic dip tube  40  ( FIG. 7 ) passes through and extends downwardly to the bottommost region of the liquid reservoir  21 . A dip tube filter  41  ( FIG. 7 ) is operatively attached to the bottom end of the dip tube  40  ( FIG. 7 ). The dip tube  40  ( FIG. 7 ) length is set to extend just above the top surface of the cap  42  ( FIG. 7 ) with the opposite end of the dip tube  40  ( FIG. 7 ) and attached dip tube filter  41  ( FIG. 7 ) pressed lightly against the bottom inside surface of the remote liquid reservoir  21 . In another embodiment not shown the remote liquid reservoir  21  if desired could be made such that it can be refilled with chemicals. In another embodiment not shown the remote liquid reservoir  21  could be molded into different shapes and with different materials as long as the materials of construction are compatible with bleach or alternative liquid chemical stored within. The remote liquid reservoir  21  may also be constructed to have a dip tube  40  ( FIG. 7 ) molded into the reservoir body or have an opening or port on the bottom of the container that the chemicals stored inside can be drawn out of. What is required is for the chemical transport tubing  19  to be fluidly connected in a leak tight manner to a dip tube or an opening or port at the bottom of the remote liquid reservoir  21  so liquid chemicals are suctioned from the bottommost region of the remote liquid reservoir  21 . The liquid reservoir cap  42  ( FIG. 7 ) having a second smaller opening or air hole  44  ( FIG. 7 ) disposed on the upper surface to allow air to enter the remote liquid reservoir  21  and prevent a suction from developing inside the remote liquid reservoir  21  as liquid chemicals are drawn out. In alternative embodiments the remote liquid reservoir  21  may not have an air hole in the cap  42  ( FIG. 7 ) but would need to have a vent disposed in the uppermost region of the body of the remote liquid reservoir  21  or some other means such as a flexible bladder or walls to prevent a negative pressure from developing within the remote liquid reservoir  21 . A hollow flexible tube that is not degraded while in constant contact with bleach and will not collapse under suction pressure such as IV tubing is used for the chemical transport tubing  19 , alternatively other types of plastic tubing that is flexible, compatible with the chemicals being used and able to withstand at least 200″ H2O vacuum level will also work. At the remote liquid reservoir  21 , a first end of the chemical transport tubing  19  is connected to the upper end of the dip tube  40  ( FIG. 7 ) that extends above the cap  42  ( FIG. 7 ) in a leak tight manner by urging the chemical transport tube  19  into one end of an adapter seal tube  43  ( FIG. 8 ) the other end of the adapter seal tube  42  ( FIG. 7 ) is then urged into the upper end of the dip tube  40  ( FIG. 7 ) along with the chemical transport tube  19 . Alternative acceptable means such as glue, packing or mechanical fittings would also be acceptable as long as they produce an airtight seal between the chemical transport tubing  19  and the dip tube  40  ( FIG. 7 ) and allow free internal flow. From the remote liquid reservoir  21  the chemical transport tubing  19  is routed up to and supported by the injection assembly  5 , the chemical transport tubing  19  passes between the water tank  25  and the water tank lid  29  to the interior of the water tank  25 , detailed discussion of injection assembly  5  and how chemicals are suctioned into eductor assembly  30  ( FIG. 5 ) to follow. The second end of the chemical transport tubing  19  is inserted into one end of a suction orifice connector tubing  34  ( FIG. 5 ). The suction orifice connector tubing  34  ( FIG. 5 ) has an internal suction orifice  33  ( FIG. 5 ) that restricts the flow of chemicals therethrough. The other end of the suction orifice connector tubing  34  ( FIG. 5 ) is fitted over a check valve  32  ( FIG. 5 ) inlet fitting. The outlet of the check valve  32  ( FIG. 5 ) is connected to an eductor suction port  31  ( FIG. 5 ). The outside diameter of the check valve  32  ( FIG. 5 ) outlet fitting is slightly larger than the eductor suction port  31  ( FIG. 5 ) inside diameter such that when the outlet fitting of the check valve  32  ( FIG. 5 ) is pressed into the eductor suction port  31  ( FIG. 5 ) a leak tight connection is obtained. The eductor assembly  30  ( FIG. 5 ) is placed internal to the toilet bowl tank  25  and secured to the injection assembly  5 . One end of the eductor inlet tube  17  is connected securely to the ballcock refill valve outlet  15 , the other end of the eductor inlet tube  17  is fitted tightly over the eductor inlet port  6 , a clamp may be used at either end of said eductor inlet tube  17  if desired to prevent any possible leaks. Refill water entering the eductor inlet port  6  flows through a nozzle  35  ( FIG. 5 ) and into the body of the jet eductor  38  ( FIG. 5 ) before exiting at the eductor discharge port  7 . A first end of the eductor discharge tube  18  is securely fitted to the eductor discharge port  7 . A second end of the eductor discharge tube  18  is connected to the inlet port of the overflow pipe 90 degree connector  23 . The overflow pipe 90 degree connector  23  is secured to the top edge of the overflow pipe  16  with a clip  39  such that the outflowing water and chemicals flow into and down the overflow pipe  16  and continue a downward flow bypassing the flush valve  11  and flowing into the bowl  24  where the refill water and added chemicals fill, clean and sanitize all surfaces contacted in route to and including the toilet bowl  24 . 
     Referring to  FIG. 2  a side view of the injection assembly  5  is shown is shown in a preferred embodiment. The injection assembly is formed from inexpensive plastic or non-corrosive metal The bottom most portion of the injection assembly  5  located inside the water tank  25  is bent away from the side of the water tank  25  to approximately a 45 degree angle; a hole is formed in the center of the bent section large enough to allow the eductor suction port  31  to pass through. While the injection assembly may be fashioned or assembled in different ways or of other materials it should hold the eductor suction port  31  above the horizontal centerline that passes through the eductor inlet port  6  ( FIG. 3 ) and eductor discharge port  7  ( FIG. 3 ) while also keeping the center of the eductor discharge port  7  ( FIG. 3 ) level with or higher than the center of the overflow pipe 90 degree connector inlet port  22  ( FIG. 6 ), this allows the eductor body  38  ( FIG. 5 ) to drain of liquid creating an air gap and siphon break between the eductor suction port  31  ( FIG. 5 ) and the eductor inlet port  6  ( FIG. 5 ) as well as the eductor outlet port  7  ( FIG. 5 ) preventing water and or chemicals from flowing back through the chemical transport tubing  19  into the remote liquid reservoir  21  ( FIG. 1 ). The air gap also prevents any chemicals from back flowing from the chemical transport tubing  19  into the suction port  31  and continuing upstream through the eductor inlet port  6  ( FIG. 5 ) and eductor inlet tubing  17  ( FIG. 5 ) to the ballcock valve  14  ( FIG. 1 ). 
     Referring to  FIG. 3  the injection assembly  5  is shown in a vertical view from inside the water tank  25 . The eductor inlet tube  17  and eductor discharge tube  18  are both held horizontal and tightly against the bottommost region of injection assembly  5  located internal to the water tank  25  by tubing ties  52  that pass through the two tubing tie holes  53  and loop around the eductor inlet tube  17  and eductor discharge tube  18 . As the eductor inlet tube  17  is attached to the eductor inlet port  6  and the eductor discharge tube  18  is similarly attached to the eductor discharge port  7 , the eductor body  38  ( FIG. 5 ) is also held horizontal. The eductor suction port  31  passes through the hole created for it near the bottom edge of the injection assembly  5  and is held securely above the horizontal plane at close to a 45 degree angle. Other means may be used to secure the eductor assembly  30  ( FIG. 5 ) but all such means must keep the eductor suction port  31  above the horizontal centerline that runs through the eductor inlet port  6  and eductor discharge port  7  while also keeping the overflow pipe 90 degree connector inlet port  22  ( FIG. 6 ) level with or lower than the eductor discharge port  7  in order to create a siphon break, the siphon break prevents water and or chemicals from flowing back into the remote liquid reservoir  21  ( FIG. 1 ) if the check valve  32  does not form complete seal while at the same time there is a slow leak past the ballcock valve  14  ( FIG. 1 ) and water is flowing slowly through the eductor inlet tube  17 . 
     Referring to  FIG. 4  the injection assembly  5  back panel  54  is shown in a vertical view from the back side of the water tank  25 . Twelve small tubing tie holes  53  are formed in the back panel  54  to allow six chemical transfer tubing ties  55  to loop around and hold the chemical transfer tubing  19  securely against the back panel  54 . The four outside chemical transfer tubing ties  55  hold the chemical transfer tubing  19  so it is held vertically on each side of back panel  54  with a large arching loop between the two sides, a status loop  8 . The status loop  8  that is formed can be adjusted by sliding the chemical transport tubing  19  through the chemical transfer tubing ties  55  so it is visible above the water tank lid  29  or shortened to be inconspicuous if desired. The center two chemical transfer tubing ties  55  align the chemical transfer tubing  19  vertically within the center gap between the two support straps  51  so it will pass into the water tank  25  and stay between the two support straps  51 . The two support straps  51  are the same height as the outside diameter of the chemical transport tubing  19  and hold the water tank lid  29  up to create a gap the chemical transport tubing  19  can pass through into the water tank  25  interior without being pinched or crushed by the water tank lid  29 . Other means may be used to support the chemical transport tubing  19  such as clips or loops molded into the back panel  54 . Any such other means must hold the chemical transport tubing  19  in such a way that it does not bend too sharply or kink. While the support straps  51  are shown as two straps that are the same thickness as the chemical transport tubing  19  outside diameter, the only requirement is that they hold the water tank lid  29  up just high enough for the chemical transport tubing  19  to travel into the interior of the water tank  25  without being pinched or crushed such that chemicals inside the chemical transport tubing  19  may pass through the chemical transport tubing  19  unrestricted. The support straps  51  may be formed in many ways and could possibly be one strap and the chemical transport tubing  19  could be routed next to the strap or possibly the strap could be molded with an internal pathway that the chemical transport tubing  19  would be fluidly connected to. The thickness requirement for the support straps  51  is that they hold the water tank lid up just high enough for the chemical transport tubing  19  to travel into the interior of the water tank  25  without being pinched or crushed and the chemicals inside may pass through the chemical transport tubing  19  with little restriction and have a fluid path to the eductor suction port  31  ( FIG. 5 ). While not required a chemical transport tubing conduit  80  can be installed to protect the chemical transport tubing  19  and it is shown secured to the back panel  54  using the two outside chemical transfer tubing ties  55  where the chemical transfer tubing  19  makes its first vertical pass across the back panel  54 . The chemical transport tubing conduit  80  if utilized protects the internal chemical transport tubing  19  from physical damage in route from the vicinity of the remote liquid reservoir container  20  ( FIG. 1 ) to the vicinity of the support assembly  5  located on back of the water tank  25 . 
     Referring to  FIG. 5  a cross sectional view of the main components that make up the preferred embodiment of the eductor assembly  30  and how they are interconnected is shown. The eductor body  38  shown is a high density polyethylene ¼″ barb×¼″ barb×¼″ barb tee. The eductor body  38  while shown to be a readily available high density polyethylene ¼″ barb×¼″ barb×¼″ barb tee could also be custom formed such as by injection molding specifically for service as a jet eductor with the same general dimensions to be described here as is the case with toilet jet eductor  75  ( FIG. 15 ). The eductor body  38  is configured with the eductor inlet port  6  and eductor discharge port  7  located on opposite sides of a tee shaped body in a straight line across from each other. Perpendicular to and fluidly connecting with the eductor inlet port  6  and eductor discharge port  7  at the midpoint is the eductor suction port  31 . One end of the chemical transport tubing  19  is inserted into a first end of a suction orifice connector tubing  34  a second end of the orifice connector tubing  34  is fitted over the inlet port of the check valve  32 . Within the suction orifice connector tubing  34  is a suction orifice  33  that is pressed into the suction orifice connector tubing  34 , approximate suction orifice  33  diameter is 0.039″. The suction orifice  33  shown is manufactured by creating the required sized orifice hole in a short section of a plastic rod that fits snugly inside the suction orifice connector tubing  34 . The suction orifice  33  limits the flow rate of the chemicals flowing into the eductor suction port  31 . The suction orifice  33  is a low cost method of controlling the chemical flow rate into the eductor assembly  30 . The suction orifice  33  requires no initial setup or adjustment and the flow rate is repeatable with each use. Other means such as pinch valves or needle valves could be placed in series with the chemical transport tubing  19  to allow a variable restriction to the flow of chemicals into the eductor suction port  31  in place of the suction orifice  33  if desired however they would increase the cost and complexity of the injection assembly  5 . What is required and described is a reliable and economical way to limit the chemical flow rate into the eductor suction port  31  and resulting concentration desired by the user. While the suction orifice  33  is shown inserted into the suction orifice connector tubing  34  it is installed at that point for convenience, other points in the fluid path that the chemical transport tubing  19  follows between the remote liquid reservoir  21  ( FIG. 1 ) and eductor suction port  31  will also work. The check valve  32  outlet port is pressed into the eductor suction port  31 . The check valve  32  outlet port having a slightly larger outside diameter than the eductor suction port  31  inside diameter creates a leak free union. While the check valve  32  is shown inserted into the eductor suction port  31  it is installed at that point for convenience, other points along the fluid path that the chemical transport tubing  19  follows between the remote liquid reservoir  21  ( FIG. 1 ) and eductor suction port  31  would also be effective and acceptable. 
     Still Referring to  FIG. 5  the suction at the eductor suction port  31  is created when refill water from the ballcock refill valve outlet  15  ( FIG. 1 ) flows through the eductor assembly  30 . One end of the eductor inlet tube  17  is fitted tightly over the ballcock refill valve outlet  15  ( FIG. 1 ), the other end of eductor inlet tube  17  is connected securely to the eductor inlet port  6 . A plastic nozzle  35  is fitted inside the eductor inlet port  6 . The nozzle  35  is held and sealed to the eductor inlet port  6  by a tight fitting rubber nozzle support ring  37  that is slipped over the inlet end of the nozzle  35 , additional support to keep the nozzle  35  from slipping into the eductor body  38  is formed by heating and flaring the inlet of the nozzle  35  slightly outward so it rest against the nozzle support ring  37 . Un-stretched the nozzle support ring  37  has an approximate internal diameter of 7/64″ and an outside diameter of approximately ¼″. The nozzle  35  reduces the internal diameter of the eductor inlet tube  6  from approximately 5/32″ down to approximately 3/32″. The discharge end of the nozzle  35  inside of the eductor body  38  is constructed to end just past the center line of the eductor suction port  31  which runs perpendicular to the axis of the nozzle  35 . In the case where the eductor body  38  is molded specifically as a jet eductor, the nozzle  35  is molded as part of the body with the above dimensions, see toilet jet eductor nozzle  78  ( FIG. 15 ). One end of the eductor discharge tube  18  is fitted tightly over the eductor discharge port  7 . A flood ring  36  with an internal diameter of approximately 5/32″ is fitted inside the eductor discharge tube  18  approximately ¾″ downstream of the eductor discharge port  7  outlet. The flood ring  36  causes the narrow jet of water exiting the nozzle  35  to back up to and flood the eductor body  38  with liquid while the eductor assembly  30  is in operation. The flood ring eliminates the need for a diffuser or converging inlet nozzle and diverging outlet diffuser at the eductor discharge port  7  to maximize the suction created in the eductor assembly  30 . Once the eductor body  38  is flooded with liquid during the time the eductor assembly  30  is operating with the ballcock valve  14  open a strong suction is generated inside the eductor body  38  and present within the eductor suction port  31 , the suction produced being powerful enough to lift and motivate a column of chemicals inside the chemical transfer tubing  19  from the floor level said toilet  10  ( FIG. 1 ) is sitting on up to and over the top edge of the water tank  25  ( FIG. 1 ) through the suction orifice  33  and check valve  34  and into the eductor suction port  31 . Refill water and added chemicals then flow and mix in the eductor discharge port  7  before flowing into the eductor discharge tube  18 . The opposite end of the eductor discharge tube  18  is secured to the overflow pipe 90 degree connector inlet port  22  ( FIG. 6 ), the overflow pipe 90 degree connector  23  ( FIG. 6 ) is secured to the top of the overflow pipe  16  ( FIG. 6 ) such that outflowing refill water and chemicals are directed into the overflow pipe  16  ( FIG. 6 ). 
     Referring to  FIG. 5 a    a cross sectional view is shown of the suction orifice connector tubing  34  with a larger suction orifice  65  inserted into the suction orifice connector tubing  34 . The suction orifice connector tubing  34  and larger suction orifice  65  capable of being installed as an assembly in place of the standard suction orifice  33  and orifice connector tubing  34  if user desires to increase the concentration of chemicals added to the toilet bowl  24  ( FIG. 1 ). 
     Referring to  FIG. 5 b    a cross sectional view is shown of suction orifice connector tubing  34  with a smaller suction orifice  66  inserted into the suction orifice connector tubing  34 . The suction orifice connector tubing  34  and suction orifice  66  capable of being installed as an assembly in place of the standard suction orifice  33  and orifice connector tubing  34  if user desires to decrease the concentration of chemicals added to the toilet bowl  24  ( FIG. 1 ). 
     Referring to  FIG. 6  a side view shows preferred way the overflow pipe 90 degree connector inlet port  22  grips the outside edge of the eductor discharge tube  18  in such a way that it does not restrict the flow of refill water and chemicals flowing into the overflow pipe  16 . The eductor discharge tube  18  should have no notable restrictions downstream of the flood ring  36 . The overflow pipe 90 degree connector  23  internal diameter is the same as or greater than the internal diameter of the eductor discharge tube  18 . The clip  39  shown is one way to hold the overflow pipe 90 degree connector  23  to the top of the overflow pipe  16  but other means may be used such as molding the clip  39  into the body of the overflow pipe 90 degree connector  23  or a separate molded plastic or bent metal fastening clip that attaches to the top of the overflow pipe  16  and holds the overflow pipe 90 degree connector  23  such that outflowing liquid will flow into the overflow pipe  16 . The overflow pipe 90 degree connector inlet port  22  should be level with or lower than the eductor discharge port  7  ( FIG. 5 ) such that an air gap and siphon break forms at the eductor suction port  31  ( FIG. 5 ) when the flush refill sequence ends and the ballcock valve  14  ( FIG. 1 ) closes. 
     Referring to  FIG. 7  a remote liquid reservoir  21  is shown. The remote liquid reservoir  21  can be manufactured in many forms and hold various chemicals that are be used to clean and sanitize, it may be refillable or disposable.  FIG. 7  shows a preferred embodiment of the remote liquid reservoir  21  that is disposable, holds an excellent cleaning and sanitizing solution, is inexpensive and readily available at many retail stores. The remote liquid reservoir  21  being a common manufactures container of household strength sodium hypochlorite or bleach. The cap  42  has a hole formed in it that is just large enough for dip tube  40  to snugly pass through. The cap  42  has a small diameter air hole  44  that allows air to pass through into the remote liquid reservoir  21  and prevents a negative pressure from developing within as chemicals are drawn out of the remote liquid reservoir  21 . A Dip tube  40  extends from the top of the cap  42  downwardly into the remote liquid reservoir  21  towards the bottommost region. The dip tube  40  being a semi rigid plastic tube enables it to keep a dip tube filter  41  in position near the bottommost region of the remote liquid reservoir  21 . The upper end of the dip tube  40  extending a short distance above the top surface of the cap  42 . The dip tube filter  41  fitted at the bottom end of the dip tube  40  having a fine mesh screen with openings smaller than the internal diameter of the suction orifice  33  ( FIG. 5 ) prevents debris and particles from entering the dip tube  40  that could travel to and clog the suction orifice  33  ( FIG. 5 ). The dip tube filter  41  being all plastic with no metal screen or fasteners is completely compatible with and not degraded by sodium hypochlorite or other common household cleaning and sanitizing chemicals. An alternative embodiment not shown is for the cap  42  to be manufactured with a dip tube  40  molded into the cap or a connection for a dip tube molded into the cap so the dip tube  40  does not pass through the cap  42  if desired. This embodiment would require an air hole  44  in the cap  42  or in the top of the remote liquid reservoir  21  above the liquid level. An alternative to the above embodiment not shown is for the cap  42  to have a leak tight connector molded in or installed that would allow a mating leak tight connector attached to the chemical transport tubing  19  to couple with forming a continuous fluid conduit from the interior of the of the chemical transport tubing  19  to the interior of the dip tube  40 . In this embodiment only the remote chemical transport tubing  19  with attached leak tight connector would need to be moved from the empty remote liquid reservoir  21  over to the full remote liquid reservoir  21  when changing the remote liquid reservoir  21 . An alternative embodiment not shown is for the remote liquid reservoir  21  to be fashioned with an internal dip tube  40  molded into the body of the remote liquid reservoir  21 . In this embodiment an air hole  44  in the cap  42  or the upper surface of the remote liquid reservoir  21  above the upper most liquid level is required. Another alternative embodiment not shown is for the remote liquid reservoir  21  to not have a dip tube instead having an opening in the bottommost surface of the remote liquid reservoir  21  that is fluidly connected to a leak tight connector such that when the chemical transport tubing  19  is fitted with a mating leak tight connector and connected to the leak tight connector on the bottom of the remote liquid reservoir  21  a continuous fluid connection is made from the interior of the of the chemical transport tubing  19  to the interior of the remote liquid reservoir  21 . In this embodiment chemicals are suctioned from the bottom of the remote liquid reservoir  21 . The remote liquid reservoir  21  in this embodiment would require an air hole  44  in the cap  42  or in the top of the remote liquid reservoir  21  above the liquid level or the remote liquid reservoir  21  will need to be made of a collapsible material to prevent a negative pressure from forming inside the remote liquid reservoir  21  that would stop the flow of chemicals out of same. 
     Referring to  FIG. 8  a cap  42  for the remote liquid reservoir  21  ( FIG. 7 ) is illustrated. The cap  42  being made of polypropylene, polyethylene, nylon or similar plastic, alternative materials could be selected as long as the material selected is compatible with common liquid sanitizing and cleaning materials such as household strength sodium hypochlorite or liquid bleach. The cap  42  contains an air hole  44  to allow air to enter the remote liquid reservoir  21  ( FIG. 7 ). Also shown is an adapter seal tube  43 . The adapter seal tube  43  shown is a short length of soft laboratory tubing with approximately 3/32″ internal diameter and 5/32″ outside diameter. The adapter seal tube  43  tube is stretched slightly and fitted over one end of the approximate ⅛″ outside diameter chemical transport tubing  19  for approximately ¼″. The free end of the adapter seal tube  43 , the end without the chemical transport tubing  19  is then inserted into the upper end of the dip tube  40  that rises above the cap  42 . The chemical transport tubing  19  with attached adapter seal tube  43  are both urged into the top end of the dip tube  40 . The dip tube  40  internal diameter of approximately 5/32″ is just smaller than the coaxially combined outside diameter of the chemical transport tube  19  inserted into the adapter seal tube  43  therefore; a leak tight and fluid connection is produced. Other methods or adapters could be used to attach the chemical transport tubing  19  to the dip tube  40  and they would be acceptable as long as a leak tight and fluid connection is formed between the chemical transport tubing  19  and the dip tube  40 . 
     Referring to  FIG. 9  an isometric drawing of a preferred embodiment of the remote liquid reservoir container  20  is shown. The inside dimensions being slightly larger than the remote liquid reservoir  21  ( FIG. 7 ) contained within. A sponge seal  62  attached to the container lid  60  allows the remote liquid reservoir container  20  to act as a double containment to the remote liquid reservoir  21  ( FIG. 7 ) contained within, helping to contain spills and keep the stored chemicals safely away from pets and small children. The sponge seal  62  also acts to secure slack in the chemical transport tubing  19  within the remote liquid reservoir container  20 , safely away from pets and small children. The sponge seal  62  also acts as a spring to push the container lid  60  up and away from the body of the remote liquid reservoir container  20 , this spring action as described later holds the container locking tab  61  up against the body of the remote liquid reservoir container  20 . To remove the lid  60  the operator must push down on both sides of the container lid  60 , then while holding the lid  60  down the two container locking tabs  61  on either side of the container must be lifted away from the body of the remote liquid reservoir container  20  and held while the container lid  60  is lifted off the body of the remote liquid reservoir container  20 . The bottom edge of the locking tab  61  being at least 3″ from the top surface of the container lid prevents a child having small hands from being capable of pushing down with his or her palms or thumbs on the upper surface of the container lid  60  while at the same time reaching and lifting the container locking tabs  61  to release and remove the container lid  60 . 
     Referring to  FIG. 10  a cross sectional end view of the line  10 - 10  on  FIG. 9  shows the container locking tab  61 . When the container lid  60  is sitting in a closed and locked position, the partially compressed sponge seal  62  pushes against the container lid  60  and the body of remote liquid reservoir container  20  and would push them apart if not held by the angled ear  63  on the container locking tab  61  being held by the interlocking angled lip on the body of the remote liquid reservoir container  20 . The container locking tab  61  cannot be lifted away from the body of the remote liquid reservoir container  20  while the sponge seal  62  is pressing on the container lid  60  and causing the container locking tab  61  angled ear  63  to be forced up against the body of remote liquid reservoir container  20  due to the angled interlocking lip on the body of the remote liquid reservoir container  20 . To lift the container locking tab  61  away from the body of the remote liquid reservoir container  20  so the container lid  60  can be lifted off the body of the remote liquid reservoir container  20 , the container lid  60  must first be pressed down towards the body of the remote liquid reservoir container  20  to compress the sponge seal  62  completely, then while holding the lid down the user can lift the container locking tab  61  and ear  63  away from the body of the remote liquid reservoir container  20 . While the locking tab  61  and ear  63  is continued to be held away from the body of the remote liquid reservoir container  20 , the container lid  60  can be lifted up and away from the body of the remote liquid reservoir container  20  as the ear  63  will now clear and can pass the interlocking angled lip on the body of the remote liquid reservoir container  20 . 
     Referring to  FIG. 11  a cross sectional end view of the line  11 - 11  on  FIG. 9  shows how the sponge seal  62  attached to the container lid  60  presses against the chemical transport tubing  19  to hold the chemical transport tubing  19  securely. An additional length of chemical transport tubing  19  is desired when replacing the empty remote liquid reservoir  21  ( FIG. 1 ) with a full remote liquid reservoir  21  ( FIG. 1 ) as it allows the remote liquid reservoir  21  ( FIG. 1 ) to be placed on a counter top, top of a closed toilet bowl  24  ( FIG. 1 ) lid or on the floor next to the remote liquid reservoir container  20  where the dip tube  40  ( FIG. 7 ) can be moved easily from the empty remote liquid reservoir  20  to the full one. Once the remote liquid reservoir  21  ( FIG. 1 ) has been replaced the additional length or slack in the chemical transport tubing  19  is placed inside the remote liquid reservoir container  20  and the top is securely pressed down and latched by the container locking tab  61  ( FIG. 10 ). The sponge seal  62  securing the additional length or slack in chemical transport tubing  19  within the remote liquid reservoir container  20  away from animals and small children. Also shown is the path the chemical transport tubing  19  follows over the rounded top edge of the remote liquid reservoir container  20  so the chemical transport tubing  19  does not collapse or kink while being pressed on by the sponge seal  62  as it exits the remote liquid reservoir container  20 . 
     Referring to  FIG. 12  a perspective view showing the preferred embodiment of the liquid chemical dispensing apparatus for toilet bowls with remote liquid reservoir is shown. The drawing shows the remote liquid reservoir  21  safeguarded inside a remote liquid reservoir container  20  to prevent small children and pets from contacting chemicals stored inside. The view also shows how chemical transport tubing  19  may be routed and secured with zip tie anchors  50  from the remote liquid reservoir container  20  along the baseboard behind the remote liquid reservoir container  20  over to and behind the toilet  10  then up to the injection assembly  5  hanging on the back of the water tank  25  in such a way that the chemical transfer tubing  19  is not out in the open and is away from pets and small children. In an alternative embodiment not shown one end of a strap could be connected to the upper region of one side of the remote liquid reservoir container  20  with a second end attached to the wall to prevent the remote liquid reservoir container  20  from tipping over. In another alternative embodiment not shown double sided tape could be added to the bottom edges of the remote liquid reservoir container  20  to prevent the remote liquid reservoir container  20  from tipping over. In another alternative embodiment not shown a wall bracket is fashioned to be secured to the remote liquid reservoir container  20  and has mounting holes for screws, drywall anchors, or other fastening means to attach the support on the wall near the water tank  25  such that the top of the remote reservoir container  20  is between floor level and the horizontal plane that passes through the top of the overflow pipe  16  ( FIG. 1 ). 
     Referring to  FIG. 13  a perspective view of an alternative embodiment of the liquid chemical dispensing apparatus for toilet bowls with remote liquid reservoir is shown. In this embodiment the liquid chemical reservoir  21  does not have any secondary containment or remote liquid reservoir container  20  ( FIG. 12 ) to keep pets or small children from contacting the chemicals stored inside the remote chemical reservoir  21 . 
     Referring to  FIG. 14  a perspective of another alternative embodiment of the liquid chemical dispensing apparatus for toilet bowls with remote liquid reservoir is shown. In this embodiment the remote liquid reservoir  21  is shown stored inside an alternative structure acting as the remote liquid reservoir container  20  ( FIG. 12 ), in this case a vanity cabinet located near the toilet. This alternate structure could be any structure that is large enough for the remote chemical reservoir  21  to be placed inside in an upright manner. A small approximately ⅛″ hole or gap would be required for the chemical transport tubing  19  to be routed through so the chemical transport tubing  19  can be fluidly connected between the remote chemical reservoir  21  and the eductor suction port  31  ( FIG. 5 ). The vanity or alternate structure could have locking devices placed on the door or entry to prevent small children and pets from contacting chemicals stored inside. The view shows where a small approximately ⅛″ hole may be drilled and how chemical transport tubing  19  may be routed to the injection assembly  5  located on the back of water tank  25  in such a way that the chemical transfer tubing  19  is not out in the open and is away from pets and small children. Another embodiment not shown is to have the chemical transport tubing  19  routed inside and protected by a larger tube or conduit that has one end connected on or near the remote liquid reservoir container  20  ( FIG. 12 ) and the other end terminating on or close to the support assembly  5 . 
     Referring to  FIG. 15  a cross sectional side view of an alternate embodiment of the eductor assembly  30  ( FIG. 5 ) with a custom molded plastic toilet jet eductor  75  and mating custom molded low profile 90 degree connector  70 . The custom molded toilet jet eductor  75  has a toilet jet eductor inlet port  77  that is sized to fit securely inside a standard toilet refill tube that is typically connected between the ballcock refill valve outlet  15  ( FIG. 1 ) and the top of the overflow pipe  16 . The inside diameter of the jet eductor inlet port  77  being the same as the nozzle  35  ( FIG. 5 ) inside diameter and is approximately 3/32″. The toilet jet eductor nozzle  78  is formed during the injection molding process and the discharge end of the toilet jet eductor nozzle  78  is constructed to end just past the center line of the chemical suction port  76  which runs perpendicular to the axis of the toilet jet eductor nozzle  78 . The chemical suction port  76  internal diameter is sized to be slightly smaller than the chemical transport tubing  19  ( FIG. 2 ) so it holds the chemical transport tubing  19  ( FIG. 2 ) securely when it is pressed into the chemical suction port  76 . The chemical suction port  76  has a fluid conduit that leads to an internal common area near the toilet jet eductor nozzle  78  exit and the toilet jet eductor discharge port  79 . The toilet jet eductor discharge port  79  internal diameter is approximately 5/32″. The toilet jet eductor discharge port  79  outside barb is sized to securely hold one end of a toilet jet eductor discharge tube  72  with an internal diameter of approximately ¼″. The other end of the toilet jet eductor discharge tube  72  is connected to the barbed end of a flood ring and tubing connection  71 . The opposite end of the flood ring and tubing connection  71  the end without the tubing barb is secured into the body of low profile 90 degree connector  70 . The inlet port of the low profile 90 degree connector is sized and has slight decreasing diameter tapper so when the flood ring and tubing connection  71  is pressed into the inlet port of the low profile 90 degree connector  70  a tight and secure connection is formed. The low profile 90 degree connector  70  is secured to the top of the overflow pipe  16  by the molded in clip. The low profile 90 degree connector  70  holds the low profile 90 degree connector  70  and connected toilet jet eductor  75  as low as possible to the top of the overflow pipe  16  in the water tank  25  ( FIG. 1 ) and allows the Liquid chemical dispensing apparatus for toilet bowls with remote liquid reservoir to be used in toilets  10  ( FIG. 1 ) that do not have a minimum of 2.5″ clearance between the top of the overflow pipe  16  and top edge of the water tank  25  ( FIG. 1 ) With the low profile 90 degree connector  70  and mating toilet jet eductor  75  the top of the overflow pipe  16  may be within 1″ of the top edge of the water tank  25  ( FIG. 1 ). In this embodiment the check valve  32  ( FIG. 2 ) is fluidly connected to the chemical transport tubing  19  ( FIG. 5 ) upstream of the toilet jet eductor  75 . The outlet of the check valve  32  being connected to one end of an open tube with the other end attached to a first end of a short section of chemical transport tubing  19  ( FIG. 5 ). The second end of the short section of chemical transport tubing  19  ( FIG. 5 ) then being pressed into the chemical suction port  76 . Preferably the check valve  32  ( FIG. 5 ) and orifice  33  ( FIG. 5 ) are attached to the inside panel of the injection assembly  5  ( FIG. 3 ). This keeps all fluid connections above the water line in the water tank  25  ( FIG. 1 ) to eliminate the chance a pet or small child pulling on the chemical transport tubing  19  could cause the unions or joints to separate creating the possibility of a siphon starting and creating a spill. 
     From the foregoing the operation of the preferred embodiment of the liquid chemical dispensing apparatus for toilet bowls with remote liquid reservoir can be clearly understood. During the time interval after the toilet  10  ( FIG. 1 ) is flushed and flush valve  11  ( FIG. 1 ) opens causing the water level in the water tank  25  ( FIG. 1 ) to drop to the point where the ballcock valve  14  ( FIG. 1 ) opens until the flush valve  11  ( FIG. 1 ) closes and the upper water level in the water tank  25  ( FIG. 1 ) is reached causing the float  13  ( FIG. 1 ) to lift and press on the lever  28  ( FIG. 1 ) to close the ballcock valve  14  ( FIG. 1 ). A suction at the eductor suction port  31  ( FIG. 5 ) is created due to refill water from ballcock refill valve outlet  15  ( FIG. 1 ) flowing through the eductor assembly  30  ( FIG. 5 ). Refill water from the ballcock refill valve outlet  15  ( FIG. 1 ) flows through the eductor inlet tube  17  ( FIG. 1 ) attached between the ballcock refill valve outlet  15  ( FIG. 1 ) and the eductor inlet port  6  ( FIG. 1 ). The refill water continues flowing into the eductor inlet port  6  ( FIG. 5 ), where the refill water passes through a plastic nozzle  35  ( FIG. 5 ) that is secured to the eductor inlet port  6  ( FIG. 5 ). The nozzle  35  ( FIG. 5 ) restricts the cross sectional area that the flowing water therein can pass through and causes the velocity of the flowing water to increase. The high velocity flow of water passing out of the nozzle  35  ( FIG. 5 ) creates a low pressure area in the vicinity of the nozzle  35  outlet and the eductor suction port  31  ( FIG. 5 ) internal to the eductor body  38  ( FIG. 5 ). Bernoulli&#39;s principle and equation describes how increasing the flow rate of a fluid through an area will create a corresponding lower pressure in that area compared to another area where the fluid flow rate is slower. In operation the high velocity fluid jet created by the nozzle  35  ( FIG. 5 ) creates a localized low pressure area in the eductor body  38  ( FIG. 5 ) and a strong suction, approximately 50″ H20 at the eductor suction port  31  ( FIG. 5 ). Being that the top of the water tank  25  ( FIG. 1 ) on most standard toilets  10  ( FIG. 1 ) is approximately 30″ above the floor. The suction created by the eductor assembly  30  ( FIG. 5 ) relative to atmospheric pressure acting on the chemicals inside the remote liquid reservoir  21  ( FIG. 1 ) is more than adequate to lift a column of liquid chemicals inside the chemical transport tubing  19  ( FIG. 1 ) from the remote liquid reservoir  21  ( FIG. 1 ) located on or near the level of the floor up to the level of the injection assembly  5  ( FIG. 1 ) hanging on the top edge of the water tank  25  ( FIG. 1 ). Chemicals suctioned into the eductor suction port  31  are then thoroughly mixed with refill water in the eductor body  38  ( FIG. 5 ) and continue to flow out the eductor body  38  ( FIG. 5 ) through the larger eductor discharge port  7  where the velocity of the water slows. The refill water and added chemicals continue to flow into the even larger diameter eductor discharge tube  18  where the velocity slows even more. A flood ring  36  ( FIG. 5 ) with a slightly smaller internal diameter than the eductor discharge tube  18  ( FIG. 5 ) is fitted inside the eductor discharge tube  18  ( FIG. 5 ) a short distance approximately ¾″ downstream of the eductor discharge port  7  ( FIG. 5 ). The flood ring  36  causes the eductor body  38  ( FIG. 5 ) to flood with liquid. Once the eductor body  38  ( FIG. 5 ) is flooded with liquid a dramatic increase in the suction level is produced and available at the eductor suction port  31  ( FIG. 5 ). The flood ring  36  ( FIG. 5 ) eliminates the need to mold or machine a diffuser or converging inlet nozzle with diverging outlet diffuser within the eductor discharge port  7  ( FIG. 5 ). Refill water along with the entrained chemicals continue to flow into the eductor discharge tube  18  ( FIG. 5 ) and flow into the overflow pipe 90 degree connector  23  ( FIG. 1 ). The refill water and entrained chemicals then flow out of the overflow pipe 90 degree connector  23  ( FIG. 1 ) and down the overflow pipe  16  ( FIG. 1 ) past the flush valve  11  ( FIG. 1 ) to the bowl  24  ( FIG. 1 ) where the treated water fills, cleans and sanitizes all surfaces contacted. The eductor discharge tube  18  ( FIG. 5 ) must not have any significant restrictions downstream of the flood ring  36  ( FIG. 5 ) or the suction created in the eductor assembly  30  ( FIG. 5 ) will be diminished. 
     Liquid chemicals stored in the remote liquid reservoir  21  ( FIG. 1 ) are suctioned into the eductor suction port  31  ( FIG. 5 ) as follows. Chemicals from the bottom of the remote liquid reservoir  21  ( FIG. 1 ) flow up through the dip tube filter  41  ( FIG. 7 ) which prevents particles or debris from flowing into and clogging the suction orifice  33  ( FIG. 5 ). Liquid chemicals continue flowing up through the dip tube  40  ( FIG. 7 ) and into the first end of the chemical transport tubing  19  ( FIG. 7 ). As mentioned earlier the liquid chemicals flow due to the strong vacuum created in the eductor suction port  31  ( FIG. 5 ). The chemicals flowing inside the chemical transport tubing  19  ( FIG. 1 ), flow out of the remote liquid reservoir container  20  ( FIG. 1 ) and follow an out of the way path to the back side of the injection assembly  5  ( FIG. 4 ). While not required  FIG. 4  shows the chemical transport tubing  19  supported by the chemical transport tubing ties  55  in such a way that it forms an adjustable status loop  8 . The adjustable status loop  8  allows the user to visually see when the remote liquid reservoir  21  ( FIG. 1 ) is nearing empty due to a large number of air bubbles traveling quickly through the clear chemical transport tubing  19  ( FIG. 4 ) or the lack of any chemicals being visible inside the chemical transport tubing  19  ( FIG. 4 ). The chemical transport tubing  19  ( FIG. 4 ) is then routed through a gap between the two support straps  51  ( FIG. 4 ) and into the interior of the water tank  25  ( FIG. 1 ) Once inside the water tank  25  ( FIG. 1 ) the chemical transport tubing is inserted into one end of the suction orifice connector tubing  34  ( FIG. 5 ) the other end is fitted over the inlet port of check valve  32  ( FIG. 5 ). The liquid chemicals flow through the suction orifice connector tubing  34  ( FIG. 5 ) and the suction orifice  33  ( FIG. 5 ) pressed into the suction orifice connector tubing  34  ( FIG. 5 ) which limits the flow rate of the chemicals added to the refill water through the eductor suction port  31  ( FIG. 5 ) and the resulting concentration that ends up in the toilet bowl  24  ( FIG. 1 ). The chemicals then flow through a check valve  32  ( FIG. 5 ) that is pressed into the eductor suction port  31  ( FIG. 5 ) and into the eductor suction port  31  ( FIG. 5 ) The check valve  32  ( FIG. 5 ) prevents chemicals from flowing backwards into the remote liquid reservoir  21  ( FIG. 1 ) between flushes, it also helps prevent a siphon from starting that could flood the remote liquid reservoir  21  ( FIG. 1 ) if water was to slowly leak past the ballcock refill valve outlet  15  ( FIG. 1 ) between flushes. Additionally the overflow pipe 90 degree connector inlet port  22  ( FIG. 6 ) being level with or lower than the eductor discharge port  7  ( FIG. 5 ) causes an air gap and siphon break to form at the eductor suction port  31  ( FIG. 5 ) when the ballcock valve  14  ( FIG. 1 ) is closed thus ensuring liquids do not back flow into the remote liquid reservoir  21  ( FIG. 1 ). 
     In the alternative embodiment with a custom molded toilet jet eductor  75  ( FIG. 15 ) shown and described earlier with the exception of the physical shape and where the components are supported and physically tied together the operation is the same as previously described in the preferred embodiment and will not be repeated here. 
     Additional modifications and improvements of the present invention may also be apparent to those of ordinary skill in the art. Thus the particular combination of parts described and illustrated herein is intended to represent only certain embodiments of the present invention, and is not intended to serve as limitations of alternative devices within the spirit and scope of the invention.
