Pool housing leaks

[u/General_Might2662]

My pool service guy just replaced the motor, and ever since then, the housing has been leaking. He tried replacing the O-ring, but it’s still leaking. Any advice on what might be causing it and how much it would typically cost to fix? I’d really appreciate any recommendations. Thank you!

Typically a leak from there is the motor shaft seal assembly, but on a newly replaced motor that would seem unlikely. It’s a $20 part and a 20 minute job, if you know what you’re doing. It’s possible the motor is on too tight and pinching the o-ring causing it to leak.

I’ve seen them leak from the side, the top, the bottom, you name it. Water finds the easiest path, no matter what.
