ABSTRACT:
An attachment for closing all varieties of flush valves before the normal amount of water has exited the tank includes a buoyant float that falls with the water level of the tank during a flush and applies its weight against the flush valve to push the valve prematurely into its seat. A float guide rod attaches to the tank wall and provides a path for the float to move upon, and a valve actuator rod is adjustably connected to the float and directly contacts the flush valve. A variety of attachments to the flush valves or actuator rod are provided for reliable performance. A combination of an entire flush valve assembly with a valve closer incorporated in its structure includes a float guide rod attached to the standpipe of the valve assembly rather than to the tank wall.
