I was lucky enough to catch someone at the LBHS after hours and picked up a disconnect, a T, some tubing, and some clamps. If I run a line off the main one, with a disconnect on it and no keg, will it contain the CO2?
I don't know if I'm always going to have 2 kegs with beer in them, so I'd hate to have to totally remove the CO2 while I take one off to clean and then have to waster CO2 on an empty keg.
