    What can cause air bubbles?

    What are some things I can check to see what's causing air bubbles in my skimmer basket?

    I've taken the pump apart to make sure it's clean. Today I used a drain cleaning bladder to try to blow out any anything stuck in the plumbing with no success.


    Can I use a snack through the plumbing?

    Here's something to read for starters. Do you mean the strainer basket on your pump?
    Pool School - Suction Side Air Leaks

    A couple of common things include the pool water getting too low (whirlpool in skimmer sucking air) or a deteriorated or unlubricated O-ring under the clear lid on the strainer basket.

    The bubble isn't extremely bad but I remember my bubble was much smaller, like the size of a pencil tip unsharpen.

    Re: What can cause air bubbles?

    I get that occasionally the day after I vacuum, and my theory is it's the bit of air I let in when I hooked up the vacuum. I do all the stuff to get rid of air in the hose, but there's always a wee bit that gets in. It goes away after a few pump starts (mine runs on high for 3 minutes, then cuts back to low each time it starts). That might be all it is, or even just a wee tiny bit getting in past the strainer lid O-ring. If that bubble was continually getting bigger, or developing every time my pump ran, I would look further into it.

    That video is a super handy way to communicate. Thanks for that!
