ABSTRACT:
A water-saving device for use in the tank of a flush toilet has a movable latch member for supporting the inlet valve float in an elevated position upon initiation of a flush cycle. A secondary float within the tank controls the latch member and releases the main float to allow opening of the inlet valve only after the tank water level has dropped by a predetermined amount. The delay in opening the inlet valve reduces the amount of water used in the flush cycle.
