Patent ID: 7735805

Claim:
A water control valve ( 100 ) for controlling the flow of water through a treatment tank ( 30 ) containing a plurality of media ( 35 ) for the purpose of (A) directing untreated water ( 10 ) through the media ( 35 ) to make treated water ( 20 ), (B) backwashing the media ( 35 ) with the untreated water ( 10 ) to dislodge any sediment to a drain ( 40 ) as waste water ( 70 ), (C) injecting a regenerating agent ( 50 ) supplied by a regeneration agent reservoir ( 60 ) into the untreated water ( 10 ) to regenerate the media ( 35 ), (D) rinsing the media ( 35 ) while providing treated water ( 20 ) for distribution, and (E) refilling the regeneration agent reservoir ( 60 ) with the untreated water ( 10 ), comprising: a housing ( 200 ) having an influent chamber ( 300 ), a backwash chamber ( 600 ), a fast rinse chamber ( 1000 ), an effluent chamber ( 1300 ), and a discharge chamber ( 1600 ), the housing ( 200 ) enclosing a supply valve ( 400 ), a backwash valve ( 700 ), an outlet valve ( 1200 ), a fast rinse valve ( 1400 ), and a bypass valve ( 1500 ), and the housing ( 200 ) having a perimeter passageway ( 800 ) and a central passageway ( 900 ), wherein: (i) the influent chamber ( 300 ) has an influent source port ( 320 ) for receiving the untreated water ( 10 ), wherein the influent chamber ( 300 ) is in fluid communication with the supply valve ( 400 ) and the bypass valve ( 1500 ); (ii) the backwash chamber ( 600 ) is in fluid communication with the supply valve ( 400 ) and the backwash valve ( 700 ); (iii) the discharge chamber ( 1600 ) has a discharge port ( 1610 ), and the discharge chamber ( 1600 ) is in fluid communication with the backwash valve ( 700 ) and the fast rinse valve ( 1400 ); (iv) the fast rinse chamber ( 1000 ) is in fluid communication with the outlet valve ( 1200 ) and the fast rinse valve ( 1400 ); (v) the effluent chamber ( 1300 ) has and an effluent port ( 1320 ), and the effluent chamber ( 1300 ) is in fluid communication with the outlet valve ( 1200 ) and the bypass valve ( 1500 ); (vi) the perimeter passageway ( 800 ) has a backwash port ( 810 ) and a perimeter port ( 820 ), wherein the backwash port ( 810 ) is in fluid communication with the backwash chamber ( 600 ) and the perimeter port ( 820 ) is in fluid communication with the treatment tank ( 30 ); and (vii) the central passageway ( 900 ) has a fast rinse port ( 910 ) and a central port ( 920 ), wherein the fast rinse port ( 910 ) is in fluid communication with the fast rinse chamber ( 1000 ) and the central port ( 920 ) is in fluid communication with the treatment tank ( 30 ).
