Hey everyone. I am trying to put together my gas setup for my keezer. I would like to be able to carb/serve at 3 different pressures. My plan is to have a primary with 2 secondaries. I have a 15cf freezer and I can fit 9 kegs inside. Im wondering what the most cost effective way to work my gas setup would be. Buying all the regulators and gas manifolds is very pricy. Is it worth having 2 secondaries? Would only having one be sufficient? Ive done alot of searching online but im just not sure what the best options are. If anyone has a similar setup to the one Im building I would love to see your setup. Any advice would be appreciated.
