ABSTRACT:
A clip-on attachment is disclosed by which an unskilled homeowner can easily transform his existing toilet or a new one into a water-saving device wherein either a total or partial flush can be selected at the option of a user. In the preferred embodiment, the attachment comprises a force-down wire which can be easily clipped onto any standard flapper flush valve, a lever arm having a lower end portion which can pivot against the wire to prematurely force the valve to close, a weighted float attached to the top of the lever arm near the full water line of the tank, and a latch to selectively prevent or allow the float to drop with the upper level of water in the tank during flushing of the toilet.
If a user decides that a partial flush is sufficient to evacuate the bowl, the latch is positioned to allow the float to freely drop with the water level. As the float drops, the lever arm pivots and forces the valve to prematurely close before the tank is completely emptied.
If the user decides that a total flush is needed, he merely switches the latch to a position where it engages the lever arm and prevents the float from dropping with the water. When the float movement is restricted, the tank operates as if the clip-on attachment is not there and completes a full flush.
