    Omg! Pool Motor has a big hole and large leak!

    image (1).jpg

    My pool pump started making an insanely loud noise and I went back there and found that there is a very big leak coming out of the bottom of the pool motor and the pool motor completely rusted through. I guess I did not do a good job of maintaining it and have barely looked at it since the summer. What needs to be replaced besides the motor?

    This is the exact motor that is on there:

    The actual pump

    Looks like motor was already replaced perviously.

    If you are leaking it's the pump and not the motor. The motor is sealed from the wet side. If there is really water coming out of motor side I would replace both

    You will have to replace the seal when you replace the motor anyway. Take the pump apart and see if there are any cracks on the wet end and make sure the impeller is in good shape. If the wet end is good then order a new motor and seal and you should be good to go.

    To be honest, I would take the pump apart before I order the new motor. On the last motor I replaced the long, thin bolts that hold the wet end to the pump sheared off. Between my old pumps and my bil's old pump we were able to get enough parts to rebuild the wet end. If your bolts shear off like mine did you will have to replace the wet end as well, and you would be better off buying a new pump. If you look around online you may be able to find some good deals.

    Do you think the motor was making so much noise because there is a big hole in the outer case? Or another reason? The thing was louder than a police siren.

    The bad seal allowed water to leak into the motor causing the big hole but also causing the bearings to rust. I believe that is what you are hearing.

    I can't get the impeller off of the motor.

    I am trying to use a wrench on the other side like step #32 but it is not working.

    Do you have a strap wrench for the impeller? Sometimes they can be very stubborn and require a lot of leverage.
