Thermostatic and Pressure Balanced Mixing Valves
Thermostatic and pressure balanced mixing valves control hot water temperatures to a safe level, giving homeowners peace of mind that they and other members of their family are protected from the dangers of accidents through scalding.
Thermostatic Mixing Valve
These valves mix hot and cold water to ensure constant, safe outlet temperatures and prevent scalding. This mixing valve compensates for variations in both the temperature and pressure of the incoming water supplies to maintain a temperature that is within 1 degree Celsius of the selected temperature. Along with providing immediate response to temperature fluctuation, thermostatic mixing valves also allow high storage temperatures, thereby reducing the risk of exposure to bacteria. The constant temperature regulation also greatly reduces the risk of thermal shock to the fixtures, increasing the lifespan of the faucet.
Pressure Balanced Mixing Valve
A pressure balanced mixing valve provides constant water pressure to prevent fluctuations in water temperature. Its internal parts are designed to safely maintain water temperature despite pressure fluctuations in the hot and/or cold supply, as when someone flushes the toilet. A requirement in some municipalities, this mixing valve ensures a scald-free environment and a constant temperature within a few degrees Fahrenheit. Check with your plumber to find out if a pressure balanced mixing valve is required in your area.
