Hi - I recently noticed a lot of air bubbles in my main return line. I immediately thought it was a suction side leak. I tried all of the usual suspects such as the unions and pump lid but everything looked good . The equipment is all new so the Pentair service people came out and said those bubbles are a by product of the in-line chlorinator. I turned the chlorinator off and sure enough the bubbles went away. It just seems like there is an awful lot of bubbles coming through that return line so wanted to see what the community had to say

My SWG also blows out a lot of bubbles, interesting enough the bubbles mainly come out of only one of my returns, not sure what to make of that. Also, the slow speed blows out a lot more bubbles vs high speed I use for skimming.
