I can't figure this out but I'm hoping someone from out kind community can help explain. I heard a squeaky high-pitched noise the other day coming from the pool, and it sounded like pinching the end of a balloon while releasing air.
I noticed that pressure was leaking from my Polaris' quick disconnect outlet. The pressure is coming out of one side, and it appears that the O-Ring that helps seal the quick disconnect to the wall adapter is being pushed out of one side and leaking water.
When I have the booster pump off, the quick disconnct O-ring appears to seat correctly.
I replaced the O-Ring and added silicone lubricant. No luck. Visual inspect of the quick disconnect and wall adapter appears to be OK.
