ABSTRACT:
A tank valve for a toilet tank is controlled by an axially vertically movable float. A releasable latch holds the float in an upper position which closes the tank valve to flow, and prevents opening of the valve to flow except when an intended mechanical flush operation is made. This prevents refill of the tank to replace water which has leaked out, rather than being released for the flushing operation.
