ABSTRACT:
A device for the reduction of water use in a WC water tank comprises a closing element which opens and closes an outlet opening of the tank and is formed as a buoyant member. The device ensures a various rationing of water discharged from the tank by a ring-shaped suppressing element provided on the closing element which hangs on a chain connected to an operating knob. The suppressing element exerts on the closing element a force which is greater than the force required to maintain the closing element buoyant.
