I finally had a chance to pick up a CO2 tank from Airgas. I bought a 20 pounder and ended up getting a nice shiney aluminum tank
Anyways, after reading through the numerous threads about leaky systems, I am a little paranoid of dumping 20 lbs of CO2 into my refrigerator. I am trying to check for leaks without emptying my tank. Here is what I have done:
I hooked up the tank, opened the valve, and set the regulator to 12 psi. I opened each valve on my distributor (3 keg system) and heard the brief hiss as each line was pressurized. No kegs hooked up at this point. I shut off the gas and closed all three of the distibutor valves. Left it like this overnight and it still had 12 lbs of pressure this morning. I opened all three valves and I will check again this afternoon. My thought is that if the system maintains the 12 psi of pressure without the tank being open, there is no leak in the gas system. Is this correct, or is my theory flawed? I know that I can still have a leak at the kegs, but I'm trying to isolate one system at a time.
