Temperature & Pressure Relief Valves

A Temperature and Pressure (T & P) relief valve is the primary "back-up" safety device that prevents water in a pressurized hot water heater from overheating. A T & P relief valve is a two-in-one safety device, which responds both to excessive temperature and to excessive pressure in a water heater. If a system exceeds its temperature/pressure limit, a water heater or pipe will burst, making the proper installation of a T&P relief valve essential.
