I got a 20lb co2 tank to replace a 5lb one, but I have a small leak and would like to find it before I go and hook up my new tank. I have a dual gauge regulator than runs to a 2 port manifold that branches off to 2 kegs. I have disconnected the kegs so I can isolate the leaks. Kegs and posts are air tight.
I have 500 psi left in the tank and I set the output to 12 psi. If I turn off the shutoff at the regulator and then turn off the co2 bottle my gauges read 500 and 12, so all good and they stay that way overnight. Then I open the shutoff at the regulator and shutoff the manifold valves. So now I only have gas between my bottle and manifold. Overnight I do not lose the 12 psi, but the 500 drops to 350. I don't understand how the 500 drops but not the 12.
Any thoughts would be greatly appreciated.
