I just started kegging. I bought a used kegerator that has an external CO2 tank, one primary regulator, and a gas hose through the door that connects to a 4-way gas splitter. I have two questions about my setup that I could use some help with. First, what happens if I have 2 different beers, brewed at different times, in separate kegs? For example, say I brew an IPA on day 1 and then a vienna lager on day 20. Since I plan to carbonate by setting a higher pressure, e.g. 30 psi, for a number of hours, before decreasing to serving pressure, what would I do when the vienna lager is ready to carbonate? The regulator would then be set at 8 - 10 psi to serve the IPA. Would I disconnect the IPA until the lager is ready to be decreased to serving pressure? Obviously, I would not be able to serve the IPA during that time. Second, having the gas hose come through the kegerator door is pretty inconvenient, since it moves every time the door is opened and closed. I would prefer to bring it in through a side, or even the back. How would I know where it is safe to drill a hole into my kegerator? How do you actually do it? Also, how would I close the old hold in the door? Thanks.
