Abstract
A toilet flushing apparatus designed to prevent excess loss of water that may happen when the flush valve stays open as the inlet valve is putting water into the tank. The initial flushing lifts the flush valve which acts in conjunction with a counter-weight and controller arm attached to the float ball arm. The controller arm supports the float ball and thus allows the intake valve to remain in the closed position until the flush valve has closed completely, at which time the float ball is lowered and water is let in to the tank.
