ABSTRACT:
Disclosed herein is a tank valve for tank-type toilets comprised of a closed upper portion adapted to extend across the opening of a valve seat, and a hollow lower portion extending downwardly from adjacent the upper portion and adapted to extend within the opening of the valve seat. The lower portion is provided with a vent hole to permit air to escape therefrom to counteract the normal buoyancy of the tank valve. Such an arrangement allows the tank valve to close and terminate the flush without having to utilize the entire supply of flush water contained in the toilet tank.
