Thread: Air Bubbles in Return Line

    Air Bubbles in Return Line

    I have air bubbles in the return line to the pool. There are no air bubbles in the skimmer at the pump. There are no visible leaks anywhere. I took apart the top valve and cleaned it and soaped all the o-rings. put it back on and No bubbles. Today I cleaned and vacuumed the pool, backwashed the filtier, and no have air bubbles again. I took the valve apart again, cleaned and soaped it but this time did not fix the problem. My guess is that it is time for a new top valve. All chemical levels are good and otherwise the water is clear. Just hazy from air bubbles.

    Your valve is unlikely the source of your bubbles. Air can only get into the lines before the pump since the water after the pump is under pressure. Do you have an SWCG?

    No SWG, When the pump is off there are no visible leaks in any exposed lines prior to the pump. Lines are buried at least 18 inches and under concrete.

    A suction side leak pulls air into the system rather than forcing water out. Therefore, you won't be able to see the leak.

    Thanks, I will check the lines the best I can and replace any ones that look matginal. The air bubbles do come and go for no apparent reason.

    Do you have a solar heater that is fairly high. If so you might have a small leak in one of the lines above pool level

    Took me over month to figureout and find mine as it diddnt let water out but sucked air in through a joint that was glued but not primed
