Abstract

A water control valve designed to control the flow of water from a source to a treatment tank having a plurality of treatment media, thereby providing a supply of treated water, and also provides other cycle controls. For instance, the water control valve directs water to backwash the media of sediment for discharge to a drain, permits regeneration of the media by directing a regeneration agent through the media, directs water through the media in a fast rinse cycle, and directs water to a regeneration agent reservoir for the purpose of refilling the reservoir. The water control valve has six valves and five motors for controlling the valve positions. The valves are fluidly connected to six chambers providing a pathway for water flow between the valves, to a regeneration injection assembly, through a central passageway or a perimeter passageway, to the treatment tank.
