What is a water heater pressure relief valve and why is it important?
A water heater pressure relief valve, often called a T&P valve, is a critical safety device designed to prevent dangerous over-pressurization within the water heater tank. If the water temperature or pressure exceeds safe limits, the valve automatically opens, releasing excess water and steam to prevent catastrophic tank failure. Regular inspection and testing of this valve are essential for ensuring its proper function. A malfunctioning T&P valve poses a significant safety risk, and its condition should be routinely checked by a qualified technician.
