Ok, so I have a 6 keg setup in my keezer with a 20lb co2 cylinder. When I first hooked everything up it worked great.. no leaks, consistent pressure. About 2 weeks later I check the reg.. and I have 0 psi in my tank! So I figured something went majorly wrong during that timeframe, so I get it refilled, pressure everything back up, spray down all of my fittings, seals, rings, etc.. with soapy water and cranked the psi up to about 25 or so and couldn't find the slightest leak anywhere? About a week later.. 0 psi! This is about the most frustrating thing ever. Does anyone out there have any clue to a potential solution.
