A:AnswerMore than likely your beer lines are half frozen and your pressure should be between 8-10 not 15.. I've seen it before you are forcing beer though an ice block turning it all to foam. After turning it off for a day,Start with your temp setting dead center. Next adjust your regulator down, you wont be able to force carbonate by craking it up, the object is to preserve and serve your favorite beer not change it. Hope this helps.
A:AnswerYes you can, I did replaced my line with a longer line and it considerably reduced my foaming problem. I have the single tap, I imagine it's the same as the dual. Remove the top cap on the tower. Than you unscrew the faucet from the tower (they have a tool for this, I did without but it was harder). To detach the line from the fauce remove the pex clamps that holds the line. Install your new line and clamp them like the old line was, you will need a tool to work with pex clamp (clinch clamp).
A:AnswerEach line is about the width of an adult finger. I cannot give an accurate measurement. The beer lines are shorter than you think because they all connect in several parts. Each line is about 2.5 feet a piece.
A:AnswerYes, we have 2 5gal. kegs installed in ours. You should be able to also install 2 7.75gal kegs, but I'm guessing you might need to mount the CO2 tank on the outside for that. It'll take up to a single 1/2 barrel keg.
A:AnswerThe reason is that the Coors and Miller kegs bell out in the middle making them to wide to fit inside. I am attaching a picture of a Coors and std keg so you can see the difference
