Went to pull a sample of this one after two weeks in the keg at 12 psi and 33F and guess what? It's flat!
My keg obviously had a leak in it so I took it apart, sanatized the bejeezus out of everything, re-applied my keg lube to the seals, and then pressured it back up and bled off the oxygen (did this last night). Checked it again this morning and now it's holding pressure just fine. I'll keep checking it over the course of the rest of the week and see if it maintains. I've never had a problem with it before though so I'm not sure what happened. Really pisses me off. My OCD hates it when things don't go as planned.
