ABSTRACT:
A flush tank is provided including a lower outlet opening and internal structure for guided movement of a free spherical buoyant valve ball into seated position in the outlet opening of the tank after the flush water has been drained therefrom. The tank includes a float controlled water inlet valve and float operated structure for at least partially unseating the valve ball from the water outlet in response to the level of water within the tank exceeding a predetermined maximum established by the float controlled water inlet valve, in the event of a malfunction of the water inlet valve to completely terminate the entrance of water into the tank as the level of water reaches the aforementioned predetermined maximum. Further, the lower outlet opening includes an upwardly facing annular concave spherical seat of the same radius of curvature as the valve ball and the seat is defined by a tapering peripheral lip portion of a resilient valve ball seat.
