Yes while kegging, first the ball lock connector was spraying beer. Replaced that and finally the closed transfer happened. Then hooked up the co2 tank set the regulator and hear a hissing sound. Put my beer down and turned off the tank. Everything was tight, turned the tank back on, open the regulator slowly hear a hissing again and no bubbles from the starsan spray anywhere on the connections .Then all of a sudden co2 started coming out full force from the back of the regulator, well there is the f’ing problem Going to the LHBS when they open at 0900
