    How do I fix the leak on my pump intake?

    New pool owner here. My pump has a leak at the place the pvc screws into the pump. All the pvc is glued in place.

    How do I fix this? Do I disassemble the impeller from the pump and unscrew? Or do I have to replumb the whole thing?

    Thanks for the help.

    Welcome to TFP!

    You need to replumb, and use unions so you can disassemble things to work on it later. Unfortunately they didn't leave you much pipe to work with. It may take some digging.

    That's kind of what I figured. Oh well.

    Do you use plumbers tape on the threads?

    If this alleviates my problems a little digging will be well worth it.

    Do I just use plumbers tape on the threads?

    Is it leaking on the suction or discharge side? If it's just the discharge side, and there's enough pipe above it, you can just cut it and put your union there and not have to dig.

    Re: How do I fix the leak on my pump intake?

    I would try a simpler fix first. Since it is on the suction side of the pump, you could just try a little pool lube around the fitting threads. The suction will draw it in and sometimes it is enough to seal the gap.

    But with that style of pump, you can unbolt the pump basket from the pump and it should unscrew from the pipe so you might not need to cut any of the plumbing.

    I really didn't want to dismantle the pump so I went ahead and redid the plumbing. I am happy to say that we now have suction and the pool is filtering.
