Pressure & Temperature Relief Valves

Pressure & Temperature Relief Valves

A P&T valve or pressure and temperature relief valve is installed on modern heating boilers, steam boilers, water heaters, and on certain other pressurized or heated tanks and equipment to release hot water and pressure should the boiler’s internal pressure or temperature rise to an unsafe level. Without a temperature pressure relief valve, your water heater would run the risk of exploding if the temperature or pressure got higher than the tank was designed to handle.
