So I am trying to build in a tap system in my existing bar. I got a built-for-keggerator fridge (EdgeStar Kegerators Beverage Appliances - BR3002)… which said that it hold 3 coney kegs… and it does, but it does not leave room for a triple air regulator (I want to keep the stouts at a lower pressure), and there is only one 5/8" diameter hole in the keggerator for an air line.
So I am trying to figure out how to do this… and one option is that I use the existing holes… and I could probably squeeze 3 lines thought the holes if I use 3/8" OD tubing…and I can get some which would still be a 1/4" ID my air lines… (https://www.homedepot.com/p/Everbilt-3-8-in-O-D-x-1-4-in-I-D-x-10-ft-Clear-PVC-Vinyl-Tubing-702098/207144353) … so aside from getting transitions from the 1/4 line to my 3/8 QD’s. and the fact that 3 3/8" air lines are going to be very tight in a 3/4" hole … is there any down side by using a smaller air line?
Am I doing too much work to get the kegs at different pressures?
The other options is to drill more holes… I am asking the manufacture if there are any cooling lines on the sides, I do not want to run into those…
