Abstract
A water control valve assembly includes a valve manifold having a mixing chamber for mixing water from a supply of hot water and a supply of cold water. The valve manifold has a water control element controlling the flow of water from the mixing chamber to a discharge port of the valve manifold. A thermostatically controlled bypass valve is in fluid communication with the valve manifold, wherein the bypass valve is configured to bypass water from the supply of hot water to the supply of cold water.
Claims24
A water control valve assembly, comprising:
- a valve manifold having a one-piece unitary body including a plurality of openings, the plurality of openings defining a hot water port, a cold water port, and a discharge port, the body of the valve manifold having a mixing chamber in an interior of the body, the hot water port, cold water port and discharge port being open to the mixing chamber where water from a supply of hot water and a supply of cold water connected to the hot water port and cold water port, respectively, is mixed in the mixing chamber and discharged from the mixing chamber into the discharge port;
- a water control element at least partially received in the mixing chamber of the body for controlling the flow of water from the mixing chamber to the discharge port of the valve manifold;
- and
- a bypass valve in fluid communication with the valve manifold, the bypass valve having a bypass valve housing with a bypass passageway therein, the bypass valve being positioned on an exterior of the valve manifold body, the bypass valve configured to bypass water from the supply of hot water to a bypass line.
