WHERE IS THE HOT WATER HEATER PRESSURE RELIEF VALVE?
Reactive Plumbing has assisted homeowners with hot water heaters for years. All hot water heaters have a valve to release pressure. These are commonly called T&P valves, and they are essential for safety. Do you know where to find your hot water heater’s T&P valve? WHAT IS A PRESSURE RELIEF VALVE? Every hot water heater has to have a pressure relief valve. These valves prevent the hot water heater from exploding under excessive pressure. Usually, hot water heaters shouldn’t exceed 150psi. When pressures rise above that, the pressure relief valve opens briefly. Then, a small burst of water releases. T&P valves also open whenever temperatures near the boiling point. WHY DOES THIS MATTER? Hot water heaters are built as a closed system. As such, excess energy can’t escape without opening the system. Since water expands as it gets warmer, pressure can build up quickly. Without a pressure relief valve, the hot water heater could burst. HOW DOES THE PRESSURE RELIEF VALVE WORK? Wh
