ABSTRACT:
A two-stage toilet flush mechanism is provided in which operation of the usual control lever to a yieldable manually-felt detent point produces a partial flush the duration of which is controlled by the position of first float with respect to the initial water level in the storage tank, and movement of the lever beyond the detent point produces a complete flush the duration of which is controlled by the position of a second float with respect to the initial water level.
