    Leaking pool pump

    Hi al!
    Water is leaking out of my pool pump. I took a picture of the area because I don't know what to call it. A few weeks ago I noticed a fine spray squirting out of the spot where I applied marine putty. I know, not the best plan. I just got in the water's way out so it made sharp right! Anyway, any advice on how to fix would be appreciated! It's coming out at the juncture where you see the glob of white marine putty.

    Was it coming from between that joint that you see there or actually a pin hole in the housing itself?

    It looks like the mechanical shaft seal that separates the dry end from the wet end has failed. You need to replace the seal. How To: Replace a Pool Motor Shaft Seal - YouTube

    No a leaking mechanical seal wont cause water to shoot up out of there. Its either the pump housing gasket leaking or a pin hole in the pump body.

    Nice to see you're bonding wire is properly attached, might want to spray some wd40 on it, let it sit a few hours then
    unscrew it / clean it up to shiny metal on the both the wire and lug then re-attach.

    I would check the plate seal first. Hayward pump correct? Provide model # and we can help you. Usually the pump seal will leak from the bottom of motor.

    The housing gasket is a SP1600T, it seals around the whole perimeter of where the seal plate meets the pump body. If that is leaking it can show up anywhere really. If its the internal mechanical seal (ps201) then it will show up underneath.

    Re: Leaking pool pump

    Thank you for all the replies! Couldn't check in from work today.
    The water did originally seem to be coming from a pinhole type leak, but now it's sort of dribbling out from the juncture. My guess would be something inside not the pump body. The model number on the pump is HST150. Thanks for the tip on cleaning up the bonding wire. Didn't know what that was!

    Yeah sometimes pinholes happen. Only real fix is replacing the pump body, or the whole pump of course. I have seen people get some extra life with a good patch job but it never lasts too long.

    So you don't think it's the housing gasket or plate seal? this pump is only 1.5 years old and the one it replaced was only 2 years old. It sounded like a jet engine.

    Re: Leaking pool pump

    I'd need to see exactly where the water is coming from to determine if its the gasket vs a pin hole. Its not the mechanical seal though, I'm certain of that one.

    The red line represents where water can get if the mechanical seal (or the seal plate itself)leaks,however I have never seen a pump leak on the top from this its always underneath the pump. The yellow line represents where water can leak when the housing gasket leaks, most of the time this also leaks under the pump and not up top, but it can.

    Re: Leaking pool pump

    So I've been away for 4 days and John has dropped off of this thread. Anyone have any ideas about what I'm delaing with? I need to either order parts and do the repair myself or call pool repair guy....any thoughts on what this is? Then I'll know if I am comfortable handiling repair.
    thank you! Lisa
