White Hydro-static Relief Valve - Protect Your Pool from Hydrostatic Pressure

Ensure the proper organization and protection of your swimming pool with the White Hydro-static Relief Valve. This essential equipment helps prevent pool damage caused by hydrostatic pressure beneath the pool shell when the pool is drained. Designed to relieve air and water buildup under pond liners, this relief valve is a spring-loaded device that opens at around 90 PSI. It effectively releases pressure, allowing the air and water to escape and preventing potential damage to your pool. Once the pressure is relieved, the valve closes back securely. To ensure the optimal functioning of this relief valve, it is recommended for pools with a minimum depth of 5ft. This depth provides sufficient pressure for the valve to effectively release the accumulated air and water. Crafted with a combination of plastic and metal materials, this hydro-static relief valve offers durability and longevity. It is designed to withstand the demands of pool maintenance and environmental factors.
