ABSTRACT:
A metering device to provide just the amount of water necessary to insure proper filling of a flush toilet bowl and trap. The metering device operates by means of gravity feed rather than pressure that is presently used which may vary the amount of water going to the trap as supply pressures increase or decrease. The metering device eliminates certain wasted water normally present during flushing and filling of the flush tank. The device in one embodiment includes a metering tank having an inlet connected to the exit sides of flush tank outlet valve. The flush tank outlet valve is connected at the upper side of the metering tank. The metering tank is in fluid communication between the flush tank and the toilet bowl and trap. The metering tank may be located in a plurality of lower positions. When the outlet valve is opened, the metering tank is also opened and filled during the flushing cycle. When the flush valve closes, a measured amount of water is in the metering tank which is then drained by gravity into the toilet bowl to fill the bowl and trap to its proper level.
