Abstract: A flush tank fill valve assembly, comprises an elongated tubular riser having a threaded upper end and a threaded lower end, the riser being adapted to be mounted by the lower end in an opening in a bottom of a flush tank, and for connecting to a source of water, a flush valve including a housing having a nipple defining a threaded inlet opening adapted to mount on the upper end of the riser, and an elongated tubular sleeve adapted to mount over the riser and having first members for limiting rotation between the sleeve and the riser, and second members for limiting rotation of the sleeve relative to the valve.

Abstract: A multiple volume flush control apparatus for controlling a flush valve in a bottom of a flush tank, comprises a flush valve having a ventable buoyancy air chamber, a vent control assembly having a venting chamber communicating with the air chamber, a first valve for selectively activating the venting chamber for venting the air chamber at a first rate, and a second valve for selectively activating the venting chamber for venting the air chamber at a second rate.

Abstract: A refill apparatus for a dual flush apparatus comprises a refill tube connected to a refill valve responsive to a drop in water level in a tank to initiate a refill flow of water for refilling the tank and for refilling a trap via an overflow tube, the refill tube having an inlet end connected to the valve and an outlet end positioned for directing water to the overflow tube for refilling the trap, and a diverting member for diverting the refill flow from the refill tube to the tank during a portion of the refill following a long flush.
