    Zoeller M53-D Pumps

    I bought a replacement pump back in 2017, I noticed it was banging on and off. Replaced the check valve, it had a slight leak, but would have failed further. Pump was still banging on and off. Pulled bolted on Pit lid, rehooked up the pump, couldn't believe the amount of water it was spraying out of the impeller seam. The only thing that I could get to stick to the plastic and metal was hot glue, after a through cleaning with rubbing alcohol. If you have one of these you might want to check it.

    It's the one with the built in float, and it's in a 24" diameter ground water pit.
