Has anyone had an auto siphon that just won't work at the most critical moment? I bought this thing from my and online HBS it's plastic and looks just like any standard auto siphon. It seems to only work before sanitizing. I test it with Star San and everything seems fine. Once it sits in sanitizer for a while, and I'm ready to rack to a bottling bucket, the piece of crap just wont suck beer into the larger tube enough to get the siphon going. Nothing I do gets it going. It's as though the rubber gasket becomes too slick with Star San to do diddly squat. As such, it's useless, because I can't use it without sanitizing. Is this common? I'm afraid to waste more money on a new one and have it to the same thing.
