I have the rear-sealing faucets and they get stuck after a few days, left even longer and they get jammed up pretty good. They came with the tower I got on CL and haven't replaced them yet but my annoyance level is currently floating around 7/10 after I spent a good part of Sunday cleaning out my kegerator, lines and faucets.
If your kegerator only has one or two taps it’s probably not a big deal as you’ll be hitting it frequently. I have a 6 tap tower so it’s a constant battle to keep them clean.
Just bought new Blichmann kettle, mash tun, burners, chiller and a new pump. Once the wife sees the ton of stuff at UPS today I suspect draconian spending cuts on their way so no perlicks for a while.
