I am on my second co2 regulator from beverage factory and it is the exact same problem as the last. I just kicked a 25lb tank of co2 and hooked up the new one. The pressure gauge with all the valves closed (4 way manifold, y splitter off of the tank, and the main valve) just shoots straight to 50 and the safety release engages. If I open it up to my kegs the same thing happens just more gradually. Am I screwing something up when I switch out my spent co2 tank for a full one? Or are these regulators seriously only good for one co2 tank and then it's garbage time? Clearly a seal valve somewhere is not sitting right, but there is no gas escaping anywhere. The pressure gauge just skyrockets. Please any suggestions I have a brand new irish red I want to try asap. Thanks.
