We rarely give a second thought to our water heaters—until something goes wrong. The water heater pressure relief valve is perhaps the most critical safety feature among the various components that keep this essential household appliance functioning safely. Yet, despite its importance, this small device often remains overlooked until problems arise. If you’ve ever noticed your water heater leaking from a small pipe at the top or side, you might be witnessing your pressure relief valve in action. But is it functioning as intended, or signaling a more serious issue? That’s what we will address here tonight!
A water heater pressure relief valve (also called a temperature and pressure relief valve or T&P valve) is a safety device designed to automatically release water when either the temperature or pressure inside the tank exceeds safe levels. This small but mighty component typically consists of a brass valve with a discharge tube that extends to near the floor.
When water temperature exceeds 210°F or pressure rises above 150 psi, the valve automatically opens to release hot water and steam, preventing potential tank ruptures or even explosions. Once pressure returns to safe levels, the valve closes again.
