I have small bubbles coming out of my return jets. Ive checked the skimmer and see no signs of air bubbles. I checked the pump basket and it did seem like air bubbles were in it so I filled it with more water, shut it very tight, andd released the air from the filter before turning the pump back on and the bubbles seemed to go away but then they came back. When i turn the filter off it sounds like air is coming from my chlorinator lid. Could this cause the problems of the bubbles? I took the lid apart and the O ring look like needs to be replaced. If this is the problem does the problem has to be fixed immediately? Im currently not using it so I'm trying to figure out if i can stop water flow to it?
