Well i have been spending what spare time i have in the last few months building and setting up my first keezer, i put together my own gas manifold and i have had to deal with a few hiccups. i keep running into gas leaks after checking all my connections and re-taping all my threads, and tightening my clamps. it seems as though the leak is coming from one of the little red valves on one of the distributers. when i turn it a little it hisses. all this equipment is brand new to my knowledge. has anyone had a similar problem... and upon fiddling with this my second question is how much gas do you have to inhale before it becomes an issue
