Hayward Hydrostatic Relief Valve 1.5/2" - White
The spring-loaded 1-1/2/2” MIP hydrostatic relief valve from Hayward is a perfect replacement for broken or worn out relief valves in a pool’s main drain sump. This crucial yet easily replaced main drain part is an important component when it comes to protecting the pool shell. If water pressure on the bottom of the pool exceeds the weight of the water towards the surface, the valve will open, releasing water into the pool which will prevent the pool shell from harmful cracking, floating, or liner bubbling. The excess water is easily pumped away from the pool. This Hayward valve is double-threaded for 1 ½ “or 2” ports and made engineered from a rugged, durable plastic fitted with a stainless steel spring that is sure to last season after season.
