Every year, thousands of people suffer serious thermal shock or scalding injuries in their bathtubs, sinks and showers. Additional untold numbers become ill due to water-borne bacteria, such as Legionella. Watts Thermostatic Mixing Valves maintain and limit mixed hot water to a desired, selectable temperature, helping to minimize thermal shock.
