Water Heater Pressure Relief Valve Expansion Tank

T p valve the temperature and pressure relief valve is an important safety device which goes off when your tank exceeds 210 degrees fahrenheit or 150 psi.

Water heater pressure relief valve expansion tank. Unlike the expansion tank which is intended to protect the piping system from pressure the tprv protects the water heater tank from experiencing. A common illustration compares having high water pressure in your home to having high blood pressure. Xt 8 thermal expansion tank is utilized on potable water lines between the backflow preventer or pressure reducing valve and the water heater for protection against water thermal expansion in residential applications. The thermal expansion relief valve can replace a water heater expansion tank because it functions similarly.

Similarities between thermal expansion relief valves expansion tanks. What size expansion tank do i need. This check valve is designed to keep water expansion from pushed back into the city water system but unless there is an expansion tank in the system the pressure has nowhere to go except to put stress on the water heater tank itself and surrounding pipes. As plumbers know the expansion tank equalizes pressure throughout the.

This ultimately protects it from damage. As the system pressure increases water enters the polypropylene lined water chamber of the tank expanding a diaphragm into. Xt 8 thermal expansion tank is the 2 gal. The temperature pressure relief valve tprv is an incredibly important life safety device on every water heater.

High water pressure can compromise the durability and the performance of the system potentially causing the tanks temperature pressure relief valve to leak as well as shower heads and faucets.
