I've changed my beer lines to the mcmaster 3/16" LLDPE hard plastic beer lines. I'm using something like 25' of line and I like my beer a bit more carbonated than average. I'm trying to go with 18 psi at 45 degrees. Problem is that the beer comes out of the lines using my perlick faucets extemely foamy (about 3/4 glass foam) and then after the foam settles, the beer is pretty flat. Seems like the co2 comes out of solution in the beer lines and totally kills the carbonation. The beer is good if I take the pressure back down to 10 psi (or lower) and then pour. Any ideas for me? I can't imagine that I need even longer lines!
