    air leaks and suction side cleaners

    Whenever I use my automatic cleaner or manual vacuum I have air in the pump and bubbles coming from the return lines. Is this a normal occurence? I don't feel any leaks at the skimmer connection I don't see bubbles coming from the hose. Please help

    This is fairly common with a manual vacuum, not so much with an automatic cleaner. It means there is an air leak somewhere, possibly triggered by the increased suction present when a cleaner is running.

    Re: air leaks and suction side cleaners

    It may be a vacuum you're seeing in the pump basket, not an air leak. Your pump may be pushing water out faster than the long vacuum hose can replenish. With the vacuum head on, my pressure drops about 6 psi, and sometimes I see that churning at the pump. Yet, when the air bleed is opened when I'm done, no air escapes! If there's no air in my filter, I can't have been sucking air.

    If you have an air bleed on the top of your filter, can you get any air out after it's been doing that for a few minutes? If no, then you can't have an air leak, and you'll be chasing a ghost looking for it.
