The Caleffi SinkMixer™ provides water at a safe and usable temperature in situations where the control of the temperature of thewater discharging from a terminal fixture is of the utmost importance, i.e. within hospitals, schools, nursing homes, etc. The SinkMixer is used in under sink and under counter applications where the user must be protected from the danger of scalding caused by hot water.The valve is designed to prevent the flow of water discharging from the mixed water outlet in the event of the failure of hot or cold supply.The compact design provided with mounting bracket allows for easy installation. The cold water outlet to the fixture eliminates the need for additional piping and tee used with three-port mixing valves. For single-pipe fixtures (tempered water only), code 521201AP includes a plug for the valve cold outlet port. The valve is complete with check valves on the hot and cold inlets and meets certification requirements for the Low Lead Plumbing Laws by ICC-ES, ASSE 1070 listed (temperature cannot exceed 120°F).
