First off, I want to apologize in advance if I am not really supposed to be posting on here since I am not doing homebrew (but I would like to some day). I bought a kegerator off of craigslist a week ago and was really excited for my new toy. However, it has been nothing but disappointing so far.
I am on my third cO2 tank in that period of time. Prior to hooking up the latest one, I put in new o rings in the connectors between the regulator and the tank and the hose from the regulator and the tap on the keg. Then I tapped the keg and turned on the co2 and did the soapy water test. There were no bubbles. I was optimistic that the new o rings might have solved the problem.
Now that I am paranoid about a possible leak I have been checking the PSI gauge. I noticed that it appeared to be dropping after I put it in the kegerator. I decided I would disconnect it from the keg and untap it. I came back and checked the gauge again and it had still lowered after I turned off the co2 on the tank. At this point, the regulator was still attached. Now I have disconnected it from the regulator too.
Any ideas? I am pulling my hair out and getting down on this kegerator thing. I read that the pressure will change when I put it in the fridge, so maybe it is not leaking at all now? Should it continue to show lower pressure even though I disconnected it from the tap and turned it off on the tank?
Thanks in advance for any help.
