I took everything out of my kegerator today to mount my regulars and manifolds onto it and clean it out real good. I cleaned all my lines, quick disconnects etc. I know really well which is the gas and liquid lines. I am having a really hard time getting the gas disconnects on any of the kegs, and some of the liquid disconnects are extremely difficult as well (I had one liquid one that wouldn't go on all the way or come off and I had to break it). Any ideas what happened?
