ABSTRACT:
A water saving device for toilets providing both partial flush and full flush capability is disclosed wherein for the partial flush, air is controllably removed from the interior cavity of a flapper valve to render the flapper valve non-buoyant to return it to its sealing position on the valve seat and terminate flow of water out of the reservoir tank. Removal of air from the flapper valve cavity is rendered a function of the dropping water level in the reservoir tank by attachment of one end of flexible tubing to the flapper valve contained air cavity, the other end of the flexible tubing communicating with the interior cavity of a cylinder, the cylinder having one closed end and one open end, the open end residing downward in the water. As water drops in the toilet tank, it also drops in the cylinder and air is sucked from the flapper valve cavity. When the water level drops sufficiently, enough air is removed from flapper valve cavity to render the flapper valve non-buoyant, and the flapper valve returns to its seat, closing off the flow of water out of the tank and into the toilet bowl. Thus a partial flush is effected. A full flush is effected by continually holding up the flapper valve.
