    Air bubbles coming from pool return

    Hi everyone

    I've just noticed a strange problem after returning from holiday.

    There is an awful lot of tiny air bubbles coming into the pool via the return.

    I've not seen any visible leaks between the pump and the pool so my only guess is there is a leaking pipe underground.

    Does anyone know how to isolate / fix this issue?

    Here's a video showing the problem.

    Thanks
    Joe

    No it's constant. I just happened to be vacuuming the pool when I took the video.
    Thanks

    Did you check the gauge on your filter? Maybe you need a backwash.

    Yeah all back washed and pressure is normal.

    You have a suction side air leak. Their is an article in pool school that will be helpful.
