After a long, drawn out fiasco with pool guys and pump motors, pump motor is replaced, up and running. Unfortunately, the pump housing was jostled when the pool guy installed the motor, and now I have a leak at the pump housing outlet. It seeps at at least one drip per second.
It previously had some very soft black sealant of some sort covering the outside of the pipe where it met the pump. Don't know what it was, but it didn't leak - but it did indicate that they'd had trouble before.
Disassembled and found that the threads are damaged on the pump housing, which appears to be black plastic of an unknown type. Looks like someone drug a screwdriver across the threads, and I'm betting that's why it's leaking.
Tried teflon tape and it leaked. Tried silicone and it leaked. Tried pipe dope and it leaked. Tried windshield urethane (for installing windshield in a car - thought it had the right mix of rubbery-ness and strength, and it lasted about half a day before starting to leak. Assuming I can get the pipe to come out (windshield urethane is tough stuff, pipe is quite possibly glued in), does anyone have any suggestions for fixing this? I don't care if I have to glue it together permanently, as long as it stops leaking. I'd just solvent weld with purple primer and clear cement, but I didn't know if that'd work on the plastic the pump is made of.
Also, how hard do I crank down? Using very large water pump pliers, 26" IIRC. Afraid of breaking the housing.
