ABSTRACT:
A float is slidably mounted on the upright overflow tube or other upright guide in the toilet tank. As the water level lowers during flushing, the float descends so that a valve actuator on the bottom of the float closes the flapper valve when the water level is partway down the tank, to conserve flush water.
When it is desired that the user have a choice between a limited flush for the flushing of liquids and a full flush, a hook is provided so that it can be manipulated to engage the float to hold the float in its raised, non-actuating position. By manipulation of the flush handle, the hook on the flush lever can be moved between the float-engaging and the float non-engaging position.
