Abstract
Apparatus operative to selectively discharge substantially all or only a predetermined portion of the water within the flush tank of a toilet. The apparatus includes an open ended float having selectively regulatable venting ports for controlling float weight and buoyancy by the water-air ratio therein. The float is constructed in a size adaptable to most existing commode flush tanks and is assembled therein by attachment directly to the flush valve thereof. The float water-air ratio is then set into the desired flush mode by selective venting of the ports whereby an unweighted float will permit a full flush and a water filled float will drive the flush valve into a premature closure for discharging only a portion of the water within the flush tank.
