<p>A toilet flushing apparatus characterized by an inherently leakproof syphon having a bridge substantially spaced above a supply tank water level, a manually discharged primer tank that floods a suction leg of the syphon to initiate flow over the bridge and through a discharge leg, and a floating flush valve and control for discharge of primer tank water to fill the suction leg closed by an inlet check valve at the foot of the suction leg, followed by continued syphoning, the primer and supply tank being automatically refilled by a float control.</p> |
