Thanks guys, I'm now convinced I need to convert to Vinyl tubing.. I saw the same stress marks where the hosing is bent over the rim of the tank for the return and intake. I have some 1" ID tubing (thanks http://www.innovationlandscaping.com/fx5/vinyltubing.html ) that I slipped over the spare aquastop valve and i must say it's not a very tight fit at all. Hose clamp is gonna prevent any leaks or coming off of there?
