WW Hydrostatic Relief Valve

The Waterway Hydrostatic Relief Valve (600-2100) is a replacement hydrostatic relief valve for in-ground pool main drain sumps. The hydrostatic valve relieves groundwater pressure from below the pool shell to prevent pool float (hydraulic uplift) when the pool is drained. Essential for pools in high water table areas. Replace during pool renovation or when the valve is stuck or damaged.
