I'm just going to lay it all out there:
Just started trying to keg about 2 brews ago, and both have been epic fails when it comes to carbonation.
Put the boiled sugar water in the bottom of the keg, let it cool, then poured the beer in on top of it. Closed it up, waited 2 weeks, hooked it up to the C02.... and I got beer juice. Pressurized the keg, and noticed that there was a small amount of air escaping from the "IN" hookup.
Hoping to avoid the issues with Brew 1, I replaced the seals around both the IN and OUT - my local homebrew store guy showed me how, so I think I did that right. I pressurized the keg to 12 PSI, then put soap and water lightly all over the top. No bubbles.
Repeated the steps from Brew 1 with the sugar water and carbonation period. Hooked it up to the C02, and I again got beer juice. Thinking that I might have just screwed up the sugar water or yeast somehow, I decided to try to force carbonate. Cranked it up to 30 PSI, shake, rattled and rolled for 15 minutes, then I put it back in the keezer for 2 hours (btw, it was cold before I started force carbonating).
Then I decided to try an experiment - I hooked the keg back up to the C02 at 30 PSI, and to my dismay, it started filling rabidly. So that means I must have a leak, right?
What's weird, however, it that when I keep it pressurized and hooked up to the C02, my CO2 levels don't become depleted (like it would if there was a leak).
Needless to say, this entire situation has me flummoxed. If you have any idea what might be wrong, please let me know!
