ABSTRACT:
A water conditioner includes a tank, and an apparatus for backflushing a bed of particulate material in the tank, which includes a tubular casing, a vertical tube in the casing, a cap on the top end of the casing, suitable valves for causing the flow of particulate material upwardly between the casing and tube, and then through a gap between the casing and cap during a backflush operation, and distributor device including a flexible, collapsible, umbrella-shaped body which is mounted on the casing immediately below the cap, and springs for biasing the body to the open position. Inlet tubes extend outwardly from the bottom of the casing approximately the same distance as the distributor for ensuring even distribution of liquid at the bottom of the bed.
