This is a 2 inch Hydrostatic Relief Valve with 2 x 1-1/2 inch Reducer Bushing for most manufacturers – two inch threads. This relief valve is made by AquaStar from superior UV-resistant engineered polymers. If using the Reducer Bushing, it must be glued into the hydrostatic relief valve using ABS glue.
This Hydrostatic Relief Valve equalizes pressure for high water tables. The fins enable you to easily twist for installation and removal.
Replacing your hydrostatic relief valve after you drain your pool is highly recommended.
