Thread: pump not keeping prime

    pump not keeping prime

    I have a 16000 gal fiberglass pool with sand filter, about 10 years old. I used to be able to use a timer for turning the pump on and off but the pump needs to be primed manually now. It has some air in the basket before the pump while running, but no air in the return lines. Suggestions?

    You have a suction side leak. Joel gave you good advice. Check those and if that's not it, run water from a hose over the suction side plumbing and pump basket.

    from looking at my specific pump, it takes a 1/4" drain plug. My local pool store can get me a hayward 1/4" plug... that's not my pump manufacturer. Is it likely to work (is a drain plug a fairly universally interchangable part)?

    They're ¼" NPT so they're universal.
