Water Heater Pressure Relief Valve Expansion Tank

The temperature pressure relief valve tprv is an incredibly important life safety device on every water heater.

Water heater pressure relief valve expansion tank.

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. Many regions require the t p valve to lead outside for added safety and some may even require two valves for redundancy. Our potable water expansion tanks are designed to absorb the increased volume of water created by thermal expansion and maintain a balanced pressure throughout the potable water supply system. The thermal expansion relief valve can replace a water heater expansion tank because it functions similarly.

The expansion tank serves as a backup system to prevent overworking your plumbing. A common illustration compares having high water pressure in your home to having high blood pressure. As plumbers know the expansion tank equalizes pressure throughout the. 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.

Both products absorb the excess pressure in the plumbing system created by thermal expansion. Xt 8 thermal expansion tank is the 2 gal. An expansion tank is always highly recommended if you have a closed loop system caused by any kind of check valve or pressure regulating valve installed on your house s water supply line. They are used to prevent plumbing system and or water heater damage as well as unnecessary relief valve discharge caused by excessive pressure from.

This ultimately protects it from damage. When the pressure supplied to your home is at a suitable level between 40 and 80 ps and has a prv or check valve the thermal expansion tank enters. The excess water volume instead of causing too much pressure on the plumbing rushes into the expansion tank and lowers the pressure in the water heater to safer levels. Similarities between thermal expansion relief valves expansion tanks.

If you have more than 80 ad pressure supplied to your home by urban water supply the expansion tank will not make any corrections. 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. Unlike the expansion tank which is intended to protect the piping system from pressure the tprv protects the water heater tank from experiencing. 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.

Its proper functioning is the difference between a nice hot shower and an explosion. As the system pressure increases water enters the polypropylene lined water chamber of the tank expanding a diaphragm into.
