ABSTRACT A buoyant outlet closure, or 'flapper' in the preferred embodiment, is vented at a selectively predetermined time in the water closet flushing cycle, causing the flapper to become non- buoyant and to drop and to close the tank outlet, effecting a premature termination of the flushing cycle, and saving the volume of water remaining in the tank. The venting is controlled by turning the externally mounted operating handle in one direction. When the operating handle is turned in the opposite direction, essentially all the water is discharged from the tank, effecting a full flush cycle.
