ABSTRACT:
A flow collector/distributor for a water treatment tank comprises a housing proportioned to communicate through a wall of the water treatment tank to provide flow communication between the tank interior and the tank exterior. The collector/distributor defines an inner end to project inwardly from the tank wall and an outward end to face outwardly from the tank wall. A plurality of slots are defined in the tubular housing, positioned to communicate with the tank interior when the collector/distributor is seated in the tank wall. The slots are of a width which is narrow enough to permit water flow therethrough while substantially preventing passage therethrough of water treatment material present within the tank. One or more one-way valves are provided to permit water flow through all of the slots from the tank interior through the collector/distributor to the tank exterior, but to prevent water flow through some, but not all, of the slots from the tank exterior through the collector/distributor to the tank interior. Also, a novel slot design is disclosed having improved flow characteristics.
