BACKGROUND OF THE INVENTION 
       [0001]    Homes typically have water pipes of ½ inch or ⅜ths inch diameter leading to each toilet. The toilet in each bathroom is commonly a gravity toilet connected to a home water supply pipe. The gravity toilet has a water closet, or tank, filled with water to a height such as 12 inches before each flushing. A gravity toilet relies upon the pressure of water resulting from the height of water in the water tank to move water into the toilet bowl for a flushing. 
         [0002]    Many commercial buildings have water supply pipes of at least one inch diameter that carry water at a pressure of at least 30 psi. The water from such pipes flows through a flushometer valve, or high flow flush valve, directly into the toilet bowl and generates a better flushing than does a gravity toilet. However, the pressure of water decreases rapidly as the diameter of the home water supply pipe decreases. If the flushometer valve receives water directly from a ½ inch diameter water supply pipe, a poor flushing results, and the toilet outlet often creates a stoppage and must be cleaned out. A system that allowed a small diameter home water supply pipe to supply water that flows vigorously enough through a flushometer valve (high flow flush valve) and toilet bowl to create a good flushing, would be of value. 
       SUMMARY OF THE INVENTION 
       [0003]    In accordance with one embodiment of the invention, a water storage apparatus is provided that allows a high flow, or flushometer toilet with a flushometer valve to be used successfully with a ½ inch home water supply pipe. The typical home water supply pipe has a diameter of ½ to ⅜ths inch and carries water at a pressure such as at least 30 psi. The water storage apparatus includes a large diameter pipe (at least ¾ inch diameter, such as 1.25 to 1.5 inch diameter) extending a considerable distance (extending most of the distance) such as at least 6 inches (and preferably at least 20 inches) between the ½ inch home water supply pipe and the flushometer valve inlet, with the large diameter pipe carrying the water at at least 30 psi. When a flushing begins, the high initial pressure such as 30 psi decreases relatively slowly because a considerable volume of water (at least 10 cubic inches) at the high pressure of at least 30 psi lies close (within 10 inches) to the flushometer inlet. 
         [0004]    The novel features of the invention are set forth with particularity in the appended claims. The invention will be best understood from the following description when read in conjunction with the accompanying drawings. 
     
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         [0005]      FIG. 1  is a sectional side view of a prior art home toilet. 
           [0006]      FIG. 2  is a partial side elevation view of a high flush toilet view of the present invention. 
       
    
    
     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0007]      FIG. 1  shows a prior art home gravity toilet  10  which includes a water closet, or storage tank,  12  that stores flushing water at a height H such as 12 inches above an outlet  14 . When a flush valve  20  is opened, water passes from the water closet through a water tunnel  22  into a toilet bowl  24 . The water passes through a trap  30  and out though a drain  32 . After each flushing, water from a home water supply pipe  34  refills the water closet through a valve  36 . The flushing water moves out of the water closet and into the toilet bowl, resulting in a less than vigorous flushing so waste may be trapped in the trap.  FIG. 2  shows part of a high flush or flushometer toilet  42  that includes a high flow flush valve, or flushometer  44 , that has a fluid connector  46  connected to a toilet inlet  50 . If high pressure water, such as water at at least 30 psi, flows directly from a one inch or 1 ¼ inch or greater diameter pipe into the valve inlet  52 , then a good flushing usually will occur. However, if the only water supply is a home water supply pipe  34  of a diameter E of 0.5 inch, then a good flushing is unlikely to occur. This is because the pressure of water at the toilet bowl inlet  50  will decrease rapidly during a flushing. Applicant assures a good flushing even though the water source is a home water supply pipe  34  of 0.5 inch diameter, by adding a water storage apparatus  60 . The water storage apparatus  60  stores water at a pressure of at least 30 psi in a water storage volume  62  that extends between points  64 ,  66 . The stored water has a volume of at least 10 cubic inches and preferably at least 20 cubic inches and this volume lies within 20 inches of the flushometer valve inlet  52 . The water storage volume includes the volume of first, second, and third conduits  71 ,  72 , and  73  that extend from the home water supply pipe  34  to the flushometer inlet  52 . An additional short pipe  75  extends upward. At the beginning of a flushing, water at 30 psi flows rapidly within the conduits to begin a vigorous flushing. The fact that a lot of water (at least 10 cubic inches) lies at a high pressure (30 psi or higher) close (within 20 inches and preferably within 10 inches) to the flushometer inlet  52 , results in the pressure of water at the flushometer inlet decreasing more slowly. The pipe  71  which lies between 10 and 25 inches from the home water pipe  34 , also helps maintain a high water pressure until near the end of the flushing, but its effect is secondary. 
         [0008]    The three pipes  71 ,  72 ,  73  that extend from the ½ inch home water pipe  34  to the 1.5 inch flushometer inlet  52 , have inside diameters A, B, C of at least 0.75 inch, and preferably 1.0 inch, with B being at least 1.5 inches. This arrangement for a water pressure above 30 psi has been found to produce good flushings (no stoppage). Since the first two pipes  72 ,  73  are closest to the flushometer inlet, their diameters are of the greatest importance. The pipes  72 ,  73  have lengths of 5.8 inch and 1.5 inch, respectively. 
         [0009]    Thus, the invention enables the use of a high flush toilet, or flushometer toilet, even though a large diameter pipe (over 0.75 inch diameter) is not available to supply a large flow rate of high pressure water directly from a home water supply pipe into the high flush valve. High pressure water is supplied to the high flush valve by an apparatus that includes a large volume conduit(s) that stores water at high pressure (at least 30 psi) very close to the high flush valve. The large volume is at least 10 cubic inches and preferably at least 15 cubic inch, and all lies within 10 inches of the high flush valve inlet. 
         [0010]    Although particular embodiments of the invention have been described and illustrated herein, it is recognized that modifications and variations may readily occur to those skilled in the art, and consequently, it is intended that the claims be interpreted to cover such modifications and equivalents.

Summary:
A flushometer toilet is used in a bathroom that has access to only a small diameter water supply pipe that usually would be useful only with a gravity toilet. A water storage apparatus ( 60 ) is provided that includes large diameter pipes (of 1.5 inches diameter) lying close to the flushometer valve ( 44 ) so at the beginning of a flushing, a large volume of water is available at a pressure of at least 30 psi.
