Abstract
A water saver outlet valve mechanism for a flush tank includes a latch for holding the valve open when pulled open by the flush handle. This latch is released by a float either at a water saving intermediate level, or when the tank is empty for a full flush, as selected by the user. A full flush is obtained by retracting an operator for the latch to an inoperative position at the water saving level, allowing the float to pass without releasing the latch. This retraction is done when the flush lever is pushed to start a flush. The float locks the latch in retracted position if the water level drops a predetermined amount before the flush lever is released.
