ABSTRACT:
A toilet tank flushing system including a ballcock valve for maintaining a storage level of water in the tank, a tank valve to release stored water on demand, and a linkage system which requires a reduced physical effort to initiate flushing. A hollow, open-ended closure for the tank valve enables a large cross-section area of discharge port to be used, and which can pass bowl refill water during the flushing sequence.
