Ok, so I went with the 20# CO2 tank and regulator (also scored a deal on a March pump) getting ready to head for the brew garage where fresh brewery yeast, a corny keg of Secession, two secondaries ready to keg (I think, at least one) and the brewmistress await! We have our first corny keg hooked directly to the 5# tank that will now be relegated to auxiliary chore/backup status. Tonight I'd like to hook up the new tank to the 5 way manifold and begin incorporating the new kegs that are ready to come online.
QUESTIONS: When disconnecting beverage service and gas lines from "active" cornies do I need to off-gas and depressurize before disconnecting and reconnecting the ball-lock disconnects? Any rules of thumb that apply to this process? It's going to be a great weekend!
