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. This lever engages the flapper valve at its center and pushes it in exactly the direction it is going, eliminating friction losses. The lever is operated to push the valve closed by a float mounted on the other side of the overflow pipe on a vertical guide. The float operates a float lever connected to the valve operated by a link. A stop for the float is brought into place by the flush lever. If the user holds the flush handle down for two seconds the float engages the stop and is inoperative for that flush. This provides a full flush.
