The 1 1/2” x 2” MPT Hydrostatic Relief Valve offers protection for in-ground pools by safely releasing built-up groundwater pressure beneath the pool shell. Constructed from durable ABS plastic, this spring-loaded valve fits standard 1-½” and 2″ male pipe thread (MPT) connections and installs directly into the main drain. This valve is a must-have safeguard against structural damage from hydrostatic lift and its self-cleaning O-ring seal reduces the risk of sticking or leaking.
