ABSTRACT:
A dual handle semi-flush retrofit kit is provided and consists of a water releasable reservoir cup the weight of which varies the effective buoyancy of the flapper flush valve, connected between the flapper flush valve and double flush handles on a toilet tank, such that if one handle is operated the toilet tank is fully flushed in the conventional way. If the other handle is operated the toilet tank is only half emptied thereby saving many gallons of water. This dual handle semi-flush retrofit kit can be easily installed by the do-it-yourself home owner.
