ABSTRACT:
The disclosed device provides a normal minimum flush cycle for water closets with the ability to override the short cycle to cause a larger water volume flush cycle. The conventional tank flapper dump valve is modified so as to retain no buoyancy during the flush cycle and a positively buoyant member is adjustably fixed on the valve operating chain an appropriate distance from the valve. When the operating handle is actuated, the added buoyancy holds the valve open while the water level in the tank falls until the added buoyancy member surfaces at which time the valve closes and the tank refills normally. Short cycle override is accomplished by merely holding the handle in the actuated position allowing a greater portion of the water in the reservoir to pass.
