Abstract
A toilet flush control system which provides control over the volume of water used in conventional tank-type toilets. The disclosed toilet flush control apparatus and method can be used in existing toilets by easily retrofitting such toilets with said apparatus. The toilet flush control apparatus may also be incorporated into the design of new toilets. The apparatus comprises a flapper-type flush valve which by itself does not have adequate buoyancy to remain open during the flush cycle of a toilet and which is equipped with an eyelet member; a buoyant member capable of imparting the needed buoyancy to the valve during the flush cycle; a flexible line connected at one end to the buoyant member and passing through said eyelet, and mechanism for adjusting the vertical distance between the flush valve and the buoyant member from outside the toilet tank. The volume of water saved during flushing is equivalent to the volume of water between the level of the flush valve and the level of the buoyant member.
