I want to build a kegerator out of an upright fridge. Nothing too fancy. It will be in my garage. Anyways, I have three pin lock kegs. All of the kits I see online only have one regulator. Can I pressurize all three kegs with one regulator? How would I keep different pressures on the different kegs? Would I need a regulator for each keg? It's my understanding from reading the forum, that I will carbonate the beer with something like 35 psi, and then dial it down to 5 to 10 psi for dispensing. Is this correct? Thanks for any advice.
