    Air in return jets

    I was wondering if its normal to have air bubbles in the water return to the pool. My pool is only about six months old and has spit out buubles since install. Maybe this is normal, possibly created in the DE filter. I have tried to bleed the filter for a few minutes w a little improvement.

    That is not normal - usually indicative of a suction side leak. Check the strainer lid first to be sure it is snug and has some lubricant on the o ring (use pool silicon lubricant - NOT Vaseline.) That is your most likely culprit.

    ??? Your thinking of the skimmer the lid to check and seal is the one on your pump that screws on above the leaf strainer.

    If you can tell us the brand and model of your pump or post a picture of it we can tell you how to remove the pump strainer pot lid.

    Spot on - Strainer should look something like this:


    and is attached to the pump.

    Re: Air in return jets

    Thanks. Feeling kinda blonde at the moment. Yes I had that off before. I assume silicone sealer is at lowes. Seems like I may have something like that at the house Will give it a shot today sometime. I had commented to the builder at the beginning but he didn't seem to think much of it. I would think it would be hard on the pump.

    Silicone pool lube, not sealer. You will want to open it again!

    Re: Air in return jets

    Thanks for replies. I tried a good dose of silicone lube. Unfortunately little improvement. I can't figure how it can pull air. The pump is a Jandy Stealth Pro Series. I have two of these. The one on the waterfall runs great. I did swap tops just to see and it still pulled air. I also switched to bottom pull only and then skimmer only. Seems like it labors more on either one than on both. Any other ideas

    Re: Air in return jets

    Do you lose prime when the pump has been powered off for a few hours? When you turn the pump off, does water squirt out of the strainer basket? Do you have chlorinator?

    Re: Air in return jets

    No on the first two but yes on the chlorinator. It does loose prime when I remove the cover of the strainer top but I would think that is normall. It reprimes itself w start
