Abstract
A flush tank water saver has an elongated semi-circular base fitting around and clamped to the overflow pipe. This base carries an operating lever on pivots close to the flapper valve pivots. One part of this lever engages the flapper valve at its center and pushes it closed. The force causing closure is provided by another part of the lever which extends beneath and generally parallel with a float lever, the two levers being connected by an adjustable chain. The second part of the operating lever is subtantially longer than the flapper valve engaging part giving a mechanical advantage to the float and causing gravity to close the valve. A positive cut off point is provided by a latch holding the operator in open position, this latch being released by the float lever. A second embodiment utilizes a spring for pushing the valve operator. Movement of the flush lever to flush latches the valve operator open. The latch is released by the float lever. Both embodiments utilize a stop for the float lever to provide a full flush.
