    Re: Loss of AC Pump Prime

    When my centrifugal pumps start to lose it, it's usually from too much impeller end-play on the shaft. A thin copper or nylon washer that reduces that play has always seemed to get them pumping like new.

    No, with metal impellers (Scott, Cruisair etc) you get erosion on the impeller leaving a stump. No vanes = no flow
