So I seemed to have completely snapped my main overflow pipe when I attempted to use Teflon tape and really tighten the pipe... Is there some sort of trick to make sure this pipe doesn't leak? I had a significant drip during my fill tests, no matter how tight I made the pipe. Decided to use teflon tape, which helped a little bit, but broke when I kept tightening the pipe. This was a used system, so maybe the rubber seal was bad...
