ABSTRACT:
A toilet flushing mechanism is described which embodies water conserving dual modes of operation providing either a full tank volume water flush or a partial flush. Selective manipulation of the toilet tank handle provides different dwell times for an air valve to remain open and causes alteration in the elapsed time required for a buoyant tank drain valve to seat so that the volume of water which drains from the tank during each cycle is altered.
