Product Overview

The Perma-Cast PV-15 Hydrostatic Relief Valve provides an important pressure-relief function in compatible in-ground swimming pool installations. Groundwater beneath a pool can create upward hydrostatic pressure, particularly when the pool water level is lowered or the pool is drained.

When sufficient external pressure is present, the hydrostatic valve allows groundwater to enter the pool, helping equalize pressure across the pool structure. This can help reduce the risk of structural damage caused by excessive upward groundwater pressure. The PV-15 features bronze construction and a 1.50-inch connection for compatible installations.
