Very odd problem i cannot solve. One tap on my 3-tap kegerator will not dispense. I pulled the keg and tested it with different tap and it works fine. When i pulled it, however, one of my other kegs wouldn't dispense. Throw this keg back in and other lines are fine again but this one still pouring nothing. I'm at a loss....and ready to lose it. Anyone gave any idea what the issue could be?
