A thermostatic mixing valve is a device which blends hot and cold water to provide your home with a reliable consistent hot water temperature at the hot water tap. The delivery temperature is usually set by your plumber during the installation. A thermal-sensitive element within the valve expands and contracts in response to changes in the temperature of incoming hot and cold water to maintain the required delivery temperature.
