ABSTRACT:
An improved ball valve for toilet flush tanks for regulating the quantity of water released from a tank in a flush includes a gauged or adjustable water inlet hole at the bottom of the ball valve and an air bleed hole at the top of the ball valve. The water inlet hole at the bottom of the ball valve is adjustable in size for selectively setting the flow rate of water entering the ball valve during a flush action, and thereby determining the time the ball valve remains open to allow flush water to drain from the tank.
