Patent ID: 8529768

Claim:
A water treatment system comprising: first and second control valves, wherein each control valve includes: a plurality of orifices; a piston, wherein movement of the piston is operative to change the flow of water through the orifices of the respective control valve; an inlet port and an outlet port, wherein the inlet port of the second control valve extends from the second control valve in a location on the second control valve that faces the inlet port of the first control valve, and the outlet port of the second control valve extends from the second control valve in a location on the second control valve that faces the outlet of the first control valve; wherein the first and second control valves each include a cavity therein, wherein the cavity is bounded by at least one wall, wherein the wall includes a first slot that is in fluid communication with the inlet port of the control valve, wherein the wall includes a second slot that is in fluid communication with the outlet port of the control valve, wherein the first and second slots are vertically and horizontally spaced apart, wherein the first slot is relatively higher than the second slot in the control valve; wherein each control valve is in operative connection with a respective brine tank and a resin tank; a manifold in operative connection with the inlet and outlet ports of the first and second control valves, wherein the manifold includes an inlet port and an outlet port and a three way valve, at least one controller, wherein the at least one controller is operatively configured to selectively operate the three way valve to direct water from the inlet port of the manifold to the outlet port of the manifold to at least one of the inlet ports of the first and second control valves.
