ABSTRACT:
An automatic flushing system is equipped with a buoyancy mechanism to unseat a valve set in a tank of a toilet. The automatic flushing system, equipped with battery power, includes sets of sensing, actuating, latching, buoyancy, unseat/seat and valve members. The battery power only provides electrical power to sensing and actuating members to release a float from an engaged position to a release position. Thus, the buoyancy of the float may unseat a valve to open a drain of the tank.
