I've been brewing for a few years and have my homebrew lines set up nicely and it pours the way I want it - but yesterday I bought a 5 gallon commercial keg from a brewery and it's 50% foam every time.
The commercial beer is a sour ale with a commercial keg D style connector that I just bought from a store, I cut my beer lines and placed the gas and beer lines on the keg. The beer lines are 8 foot vinyl in a double tap tower, I replaced them yesterday after reading a forum about how 6 feet is too short and increased the beer line length to 8 feet.
The keg seemed cold, it also sat overnight for 10 hours undisturbed. I read it could be a missing washer in the D connector but I don't see anything missing. There is a small black rubber washer in the connector just under the vertical beer line from the commercial keg. There are small bubbles in the beer lines, the foam comes out very fast like the PSI is too high, the first half of the pour is foam and the second half of the very quick pour is liquid. I've tried 5 PSI and up to 15 PSI with not much change.
The tap is a perlick with adjustable flow on it, and that doesn't seem to help at all. Temp is right around 38F. I released the gas from the commercial keg several times to see if it was overpressured.
The homebrew out of the cornelius keg still pours well with the same lines and temp. The beer doesn't taste overcarbonated. You can see the small bubbles in the line in the next to last image below. It doesn't seem to change at 5 PSI or 12 PSI.
