I finally sacked up and bought a 4-way regulator and hooked it up last weekend. I sprayed with Star San and found no bubbles. Thursday when I went to pull a beer nothing came out. 2 of 3 of the kegs I had hooked up had no CO2 when I pulled the relief valve. One keg kept pressure. I have been tightening every clamp, but still have a leak.
I have been trying pinpoint the problem by closing the valves on the 4-way and cranking up the CO2 regulator connected to the tank then shutting it off. But 30 minutes later the pressure on that regulator is back to 0. Is it safe to assume the leak is somewhere between the tank and 4-way input or will a tank that is shut off always loose pressure like that?
