Abstract

An improved ballcock assembly for a toilet water reservoir which provides quiet reservoir refill operation without requiring a conventional water discharge hush tube. Quiet refill operation is provided by discharging refill water through a plurality of openings which create individual streams of water which flow along the side surfaces of a standpipe having longitudinally extending external ridges or walls. The walls maintain the separation of the individual water streams which cascade down the standpipe surface. The outside surface of the standpipe is preferably tapered outwardly from top to bottom so that the water flows along a tapered surface which reinforces the cascading flow regime. The reduced flow for each stream and the cascading flow action combine to provide quiet refill operation. Since the ballcock assembly refill openings are above reservoir tank water level, water normally cannot be sucked through them and into the water supply system.
