ABSTRACT:
A flush control device for use in a toilet tank of the type containing a standpipe and a flap valve pivotally mounted on the standpipe for closing an outlet in the bottom of the tank includes a cylindrical sleeve for slidable mounting on the standpipe and a bulbous float at the bottom of the sleeve. The float is defined by an upwardly opening first cup integral with the bottom end of the sleeve, and an inverted second cup slidably mounted on the sleeve, so that the buoyancy of the device can be changed. Thus, the water level at which the flap valve closes, and consequently the quantity of water discharged through the outlet can be controlled.
