I'm new at this and thought I'd take the dive and switch from bottling to kegging. I ordered a couple of "used" corny kegs. One came with what I assumed was a "standard" lid and the other with a racetrack lid. I replaced ALL of the seals including the ones I found inside of the posts. One of the lids had a relief valve which was stuck in the closed position (can't pull it open and can't remove it). No leaking everything great. But. . . I wanted to replace the lid with the defective relief valve and ordered a "standard" replacement. Guess what? It doesn't fit. My keg seems to be some weird size that is not a standard or a racetrack, but some mixed version. Just for fun, I've included links to pictures for you to enjoy. If you recognize what it is and know where I might find a replacement with a relief valve, give me a shout!
