Abstract
A valve system enables use of a standard single line faucet with a water treatment system. The valve system may include a housing having ports for receiving untreated supply water, supplying water to a water treatment system, receiving treated water from the water treatment system and supplying treated water to a dispenser. The valve system includes an automatic shutoff device that prevents water from flowing into the water treatment system when the dispensing faucet is closed and allows water to flow into the water treatment system when the faucet is open. The valve system may include a pressure relief mechanism that removes pressure from the water treatment system when the faucet is closed and a check valve for maintaining a desired amount of pressure within the valve system.
