Your SWG will put bubbles in the line (chlorine in gas/vapor form) is the return with the bubbles the one with the shortest run of pipe from the valve to the pool? Mine is(where the bubbles come out)Ksnewman said:Also one of the returns seems to have larger air bubbles coming out intermittently. We did 2 pressure tests and everything was good. Other returns - no large bubbles. What would be causing this?
Thanks
