Has anyone else experienced problems with a Nature2 Fusion eating the o-ring that is under the chlorine injector cap? The pool supply store says that I have an air leak. The pool builder says the tiny bubbles I see in the returns are from the O3 generator. I tried replacing the o-ring with an AN-343 o-ring made from Viton (FKM) which is supposed to be reasonably resistant to chorine dioxide, but that one only lasted about 60 days (versus 30 for the oringinal Buna o-ring). I am trying to figure out if o-ring destruction is inherent to the Nature2 fusion design or if I really do have an air leak or some other problem.
Pool has a one-year warranty and was completed February 2011. 13.5K gallon inground with Intelliflow, sand filter, O3 and Nature2 Fusion.
