Tried searching and it seems like almost all of the questions are the opposite of mine, if there is another thread that answers me, just link it. My currents set-up is a 2 tap, converted mini fridge that holds 2 corny kegs. I haven't been homebrewing as much lately so I was considering keeping a commercial 1/6 bbl keg on tap plus on of my homebrews. 1) is this possible, just have one CO2 gauge that splits off to both kegs and 2) what will I need to hook the taps into a commercial keg (and CO2 tank into the keg as well)? Thanks in advance.
As far as splitting the co2 you have three options: 1)"Y" splitter on the regulator 2)manifold with two splitters 3)secondary regulators to adjust different pressures to the different lines. as far as "commercial" kegs you need a standard "D"system coupler if doing domestic beer and a hose barb,nut and washer to hook up beer line. or a set of these so you can leave ball locks on.
zero has it all sorted. be sure you measure the height of your mini fridge as a 1/6 is just slightly taller (and wider) than a typical corny but the coupler and line can add another few inches of height. a low profile coupler is available if needed. otherwise you are good. Cheers.
