Troubleshooting beer line

[Got Trub?]

I'm stumped. I finished my kegerator 2 weeks ago and based on all the wisdom posted here and elsewhere set it up as a balanced system. I carbonated a keg of German Pils at 12psi @ 40F for 2 weeks. I have tried both a 10ft and 12ft length of 3/16 beer line and no matter what I do I get nothing but foam. I've tried reducing the pressure, I've tried increasing the pressure - no difference. I have noticed that the beer in the line is foaming and after a few minutes half the line is gas . When pouring you can see it is forming bubbles in the tubing and then as it comes through the faucet it turns completely to foam. Again it doesn't matter if I am using 4psi, 12 psi or 16psi. I noticed that there is a temperature gradient in the freezer from top to bottom so thinking that was the problem I installed a 12V PC fan to circulate the air - no help.

Any thoughts?

Thanks in advance.

It kind of sounds like your beer may be over carbonated. My regulator's do not give me the exact pressure that they read on the gauge. If I turn my regulator up to 12 PSI I will eventually get an overcarbed beer that foams. If I turn it down to 10 PSI I get perfect results. Try purging the keg a few times a day over a couple of days with the pressure at 8 PSI and see what happens. There may be a better way to get some of the carbonation out of the beer but that is what I do.

When you turn your reg down, you have to purge the keg multiple times, and wait a while for the CO2 in solution to come out, and the carb level to drop.

Good thought. I'll dial it down and let it re-equilibrate for a few days. I'd assumed it wasn't overcarbonated as it is almost flat once in the glass but maybe the CO2 has been stripped out with all the foaming.

Thanks

yeah, when you get excessive foaming, it really flattens out the beer.
