Abstract
A water control fixture includes a fixture body in fluid communication with a pressurized supply of hot water and a pressurized supply of cold water. The fixture body interconnects the supply of hot water and the supply of cold water. The fixture body has a spout outlet configured to dispense water from the fixture body. At least one operating valve is coupled to the fixture body for controlling a flow of water to the spout outlet. A bypass valve is disposed in the fixture body for controlling a recirculating flow of water through the fixture body. The bypass valve blocks and permits recirculating flow from the supply of hot water to the supply of cold water based on a temperature of the water.
Claims20
A water control fixture, comprising:
- a fixture body in fluid communication with a pressurized supply of hot water and a pressurized supply of cold water, wherein the fixture body interconnects the supply of hot water and the supply of cold water, the fixture body having a spout outlet configured to dispense water from the fixture body;
- at least one operating valve coupled to the fixture body for controlling a flow of water to the spout outlet;
- and
- a bypass valve disposed in the fixture body for controlling a recirculating flow of water through the fixture body, the bypass valve blocking and permitting recirculating flow from the supply of hot water to the supply of cold water based on a temperature of the water.
A water control fixture, comprising:
- a fixture body in fluid communication with a pressurized supply of hot water and a dedicated return line, the fixture body having an interior chamber hydraulically connected to the supply of hot water and the dedicated return line;
- an operating valve coupled to the fixture body for controlling a flow of water from the supply of hot water;
- and
- a bypass valve removably disposed in the interior chamber for controlling a recirculating flow of water from the supply of hot water to the dedicated return line.
