So I've had quite a few issues with my Keg Connection setup so far. I finally finished my Keezer and mounted my regulators to the collar. I hooked up the gas, pressure on the dials rises fine, hooked up the gas line to a keg, opened the valve on the regulator to pressurize a soda keg, and right around 28-30 PSI, the needle starts rattling like wild back and forth. The odd darn thing is that if I close off the valve on the regulator and then reopen it, the rattling stops on the needle and dosn't come back... It's so odd! I'm assuming this isn't normal???
