VACUUM RELIEF VALVE
The vacuum relief valve is installed at the base of the manifolds. The valve provides
‘vacuum relief’ when the solar pump turns off by allowing the water to drain
back to the pool. Air is drawn into the system through the top of the valve due to
gravitational forces opening the internal seal. When the pump turns on water
pressure will re-seal the vacuum relief valve. Air should be expelled into the pool
within 2-3 minutes depending on the size of the system and during this period the
resulting turbulence created will cause some associated noise.
Vacuum relief valves should be inspected regularly (2-4 months) during the
months of operation. If it is leaking or blocked (no surges of air returning to pool)
it should be cleaned. This can be done by pulling the cap off the top of the valve.
Remove visible obstructions and wash the components with water. The solar pump
must be turned off before cleaning commences.
ATTENTION
Vacuum relief valve maintenance
Failure to correctly install a vacuum relief valve in your system
or inspect and maintain its operation will void all warranties
related to collectors, pipe work and fittings.
