    Intex 14" sand filter with air leak when vaccuming

    Hello
    I know this topic has been discussed but i still can not find the correct answer.
    I know that the plunger has a vacuum break valve so i have covered it and also completely bypassed it. However even when i bypass or cover the valve i am still getting air in the leaf basket when i use the vacuum. So there is air leak somewhere. I have replaced the hose so i know they are good. I have rechecked and re tightened the air release and sentiment release and also the cap on the leaf basket. How do i find the air leak since i have done everything or is this just a product of the system? Help i need to vacuum the pool.

    Are you sure it's air and not just a void? When I vacuum I see all kinds of empty space and turbulence in the pump strainer, yet once I unhook the vacuum it disappears and there's never any air when I open the air bleed. If I crack the spa valve to reduce the suction on the vacuum, the "air" disappears. It's pump cavitation.

    The leaf basket goes to half full and starts sucking air at that point so i doubt it is a void.
