Abstract
A metering device for use in a conventional flush toilet having a flush tank for regulating the amount of water utilized in filling the flush bowl and trap of the toilet. The device includes a metering tank disposed in the flush tank which is filled with a fixed volume of water, a first conduit from the flush tank inlet water supply into said metering tank, a second conduit disposed between the metering tank and the overflow tube which is utilized to refill the bowl and trap, and a valve means disposed in said second conduit for regulating the flow of water from the metering tank into the overflow tube. Applicant has determined that the conventional toilet having a flush tank utilizes an excess amount of water which is lost during the flushing action in refilling the flush bowl and trap. The metering tank and valve delays the filling of the flush bowl and trap until after the flushing action is completed and regulates the total amount of water receivable into the trap and bowl. The device is also useful with partial flush systems to insure that the trap and bowl are adequately filled.
