ABSTRACT:
An actuator tube slidably embraces the overflow tube on a toilet tank and has an actuator flange at the lower end thereof. An actuator sleeve slidably embraces the actuator tube with stops limiting the relative sliding distance. An actuator surface is also mounted on the sleeve so that, when the flapper valve at the bottom of the toilet tank is raised to release flush water, the float descends and with it descend the actuator tube and flange, as well as sleeve and actuating surface. The flange thrusts the flapper valve partway down, and the actuating surface sliding down the tube finally closes the flapper valve before all toilet tank water is released to thereby conserve water.
