I know there's a learning curve here, and I kind of blame myself, but these co2 leaks are really starting to piss me off. My first keg went great! Second, my bad. I hooked it up, then shifted stuff around, the MFL connection came loose, empty tank. I had a second ready, no big... tightened, hooked up, bubble test, and we're good. Hooked up the third, and my second tank is empty. Ugh... 2 tank replacements coming up. This could be a pricey hobby, if I keep making a habit of venting co2 into my basement.
