SOLARPOOLSUPPLY Vacuum Relief Valve for Solar Pool Heaters - 2.3


Product description

Size:2.375" (2-3/8") O.D.


Vacuum relief valves allow air into your solar pool heating panels amp; piping whenever there is a vacuum created by a void of water pressure. A valve must be installed on every solar pool heating system to allow air into the system when pump shits off. This relieves the vacuum created by the water draining back down the supply line and into the pool. This process is necessary to keep water from collecting amp; freezing inside the riser tubes if temperatures were ever to drop overnight. It also keeps the air from stagnating inside the collectors amp; piping.

  • A ball spring (5#) type check valve is typically installed at the highest point in a solar pool heating system. By allowing air to enter the pool solar panels, it aids in gravity drainage of solar pool collectors and piping.
  • Internal components feature a Viton o-ring, glass-reinforced ball, and 5# stainless steel spring.
  • Typically installed using a rubber hose type connector and hose clamps, which are sold separately.


Compatibility: Will work with any solar pool heating system that has round 1.5” or 2" I.D. header manifolds and makes attachments with rubber hose type connectors.
