I have a Haier kegerator that I bought a couple of years ago and have been slowly upgrading. I now have a 3 faucet tower with a single co2 regulator that has a split connector with 1 line directly to a keg and 1 line to another splitter that goes to two more kegs. I just got a secondary regulator and all of it is getting a bit much to manage. I want to mount them all to the inside of the kegerator, but am concerned that will damage the insulation. Has anyone tried this before?
