I didn't think this was possible but I seem to have an issue with my Chlorinator sucking air, and a lot of it! I noticed that I have a lot of air being returned into my pool, after investigating each device, I found a lot of rumbling air-type noise coming from my chlorinator. I noticed that if I turned it up to max the rumbling would go away and all bubbles would stop from coming into my pool. If I turn it back to 5 where I normally keep it or really anywhere below max it starts rumbling and blowing bubbles back into the pool. I thought maybe the lid was not on right and adjusted it several times, also thought maybe the chlorine tables may have gotten stuck in the in or out valve system and I did a quick cleaning and rearranged all the tabs. Still no change, no Bubbles on Max and tons or bubbles on any other setting. I did some research to see if this was a common issue and only found that what is happening is seemly impossible that if the chlorinator had a leak it should be squiring water not sucking air. My chlorinator is the last device before my outflow valve. Model # CL2002S.
Thanks for any help.
