    Why are Tempering Valves important?

    Hundreds of people every year are burned and seriously injured by domestic hot water. When showering, users may set the shower at a comfortable temperature, however, if the cold water supply drops when someone runs a tap or flushes the toilet, the water temperature will be far too hot. Tempering valves monitor the temperature of the water and prevent it from reaching scalding temperatures, even if the cold water supply drops.
