Water Heater Pressure Relief Valve Expansion Tank

Both products absorb the excess pressure in the plumbing system created by thermal expansion.

Water heater pressure relief valve expansion tank.

The temperature pressure relief valve tprv is an incredibly important life safety device on every water heater. The expansion tank serves as a backup system to prevent overworking your plumbing. Many regions require the t p valve to lead outside for added safety and some may even require two valves for redundancy. The thermal expansion relief valve can replace a water heater expansion tank because it functions similarly.

A hot water heater expansion tank is the cost effective solution to thermal expansion and high water pressure. 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. Similarities between thermal expansion relief valves expansion tanks. What size expansion tank do i need.

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. This ultimately protects it from damage. 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. Unlike the expansion tank which is intended to protect the piping system from pressure the tprv protects the water heater tank from experiencing.

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. A common illustration compares having high water pressure in your home to having high blood pressure. Its proper functioning is the difference between a nice hot shower and an explosion. They are used to prevent plumbing system and or water heater damage as well as unnecessary relief valve discharge caused by excessive pressure from.

Xt 8 thermal expansion tank is the 2 gal. As plumbers know the expansion tank equalizes pressure throughout the. As the system pressure increases water enters the polypropylene lined water chamber of the tank expanding a diaphragm into. 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.

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. 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.
