I just built a new kegerator that has a 2 tap tower. The new tower I ordered has 5ft 1/4" lines.

I always naturally carbonate my beer as I like to have 3-4 kegs conditioning.

I have read a lot about various serving pressures for force carbonated beer. What serving pressure should I be using for naturally carbonated beer?

Determine from your amount of priming sugar the number volumes CO2 you have in the beer.

Determine your kegerator (well, the beer's) internal temperature.

This will give you your pressure needed: http://sdcollins.home.mindspring.com/ForceCarbonation.html

FYI, 1/4" lines at only 5' will be too short (many people on this forum suggest 5' is too short even for 3/16"). Are you sure they're 1/4" lines? A lot of times, it's 3/16" line that's fitted onto a 1/4" barb. You might want to check this. If they're actually 1/4" ID, buy some new 3/16" ID lines while you have the chance before you assemble it or you'll be pouring lots of foam.
