摘要： A system for controlling and saving water to be used with a toilet flushing apparatus permitting adjustable partial flush and full flush capabilities. A control housing having a pin inserted therethrough has a pointed tip portion entering an aperture formed in a bottom end of the control housing providing an adjustable needle valve. The effective size of the needle valve determines the rate at which water expels from the housing. A flexible tube attached to the control housing leads to a cavity in a flapper valve. The flapper valve covers a drainage port in a holding tank of a toilet when the toilet is unflushed. When the toilet is flushed, air is drawn from the cavity of the flapper into an inner chamber of the control housing as water leaves the control housing, thereby causing the flapper to change from a positive to a negative buoyancy state. The flapper can therefore be reseated upon the port before all the water has left the holding tank. A clamping mechanism on the lever of the flushing apparatus allows the partial flush mode to be quickly disengaged permitting full flush capabilities.
