Temperature Pressure Relief Valves are essential safety devices used to protect hot water systems from explosion or damage caused by excessive pressure or temperature. They are installed on water heaters, boilers, and other pressure vessels to prevent them from rupturing or exploding due to overheating or excessive pressure. These valves work by releasing excess pressure or temperature out of the system, thereby stabilising the pressure and temperature levels. They are recommended by experts as a safety measure for all hot water systems and should be regularly checked and maintained by a qualified professional.
