ABSTRACT:
A pressure flush tank assembly for toilets which includes a combination of a flush valve coordinated with an air induction valve and refill valve to insure successful repetitive operation, together with a construction which prevents back-flow in the event of a negative line pressure and an initial outflow control to reduce noise and eliminate back bounce from the toilet bowl.
