Thanks for the advice guys, it is much appreciated. So here's the update. The pool guy came to attempt to fix the leak, says it's the o ring like you guys suggested, so he replaced the o ring. Still leaking, he could not fix the leak with the o ring (still wanted service fee). He said it could be the clamp. If you move the clamp it always leaks at the two areas where the ends of the clamp meets. Any thoughts?
