Thread: Weird pump action

    Weird pump action

    Long story short. In ground pool with Hayward Super Pump and S-200 filter.

    I was vacuuming the pool to waste and suddenly I heard a whoosh-regular flow from the discharge. I went to the pump and saw the basket/pump water volume go to about ¾ full to ½ full (the whoosh) then back to ¾. It did not fill the basket.

    Since I was vacuuming, I though that perhaps something may have been vacuumed into the impeller of the pump. I took the motor off and cleaned the impeller. (There was nothing significant there.)

    When I restarted the same ¾ to ½ full action was repeated.

    When this is happening, there is flow through the system all be it at a minimal force.

    What is going on?

    Kinda sounds like an obstruction in the line. Did you use a vacuum disc or did you put the vacuum hose right into the hole of the skimmer?
