ABSTRACT:
A toilet flush system designed for manual control of the amount of water used for a toilet flush cycle uses a tank ball, flapper valve, or other type valves to control the closing of a reservoir outlet at selected times prior to or upon completion of the normal flush cycle. The tank ball or flapper valve is modified to overcome its buoyancy such that it rapidly closes the tank reservoir to thereby terminate the flush cycle when the handle of the toilet is released. By maintaining the handle in the operated position, the individual flush cycle can be controlled dependent on the waste to be disposed of, thus permitting a significant saving in fresh water. The buoyancy of the valve is overcome by utilizing a water absorbing material such as sponge material within the valve which, when primed, increases the weight of the valve.
