I hope someone can help me with this problem because I'm stumped. I brewed a 10 gallon batch of IPA and split it between two kegs. Both taps on my homemade kegerator are exactly the same (10ft of 3/16" line, perlick 525ss taps). I have a two product taprite regulator and put both kegs through the same carbonation schedule (30psi for 24 hours, 20 psi for 24 hours and then serving pressure of 12psi at 38 degrees). One keg was carbing up noticeably quicker than the other, so I drank from it exclusively, and it was pretty much perfectly carbed by the time it kicked. I then started drinking from the other keg, and it was still basically flat even though it had been on co2 the whole time. I thought there might be a problem with that leg of the regulator, so I switched the beer and gas lines from the first keg to the new one. It did seem to start carbing up better after that but just as it started to develop some bubbles and a nice head it went almost completely to foam. Literally one pour was almost acceptable and the next pour was 3/4 foam. Then the foaming problem just continued pour after pour.
I thought that there might be some kind of restriction in the dip tube or liquid out post of the new keg that was stripping out CO2, so I switched them with the ones fist keg to see if that would help, but it didn't. I don't think the foaming could be from overcarbing or warm beer lines, so I'm not sure what else it could be. They only way I'm able to get even half a glass of beer without excessive foam is to drop the regulator to around 4psi and let it trickle out. At this point, I'm think I'm just going to push the beer to another keg, but does anyone have any ideas might be wrong with this keg in particular or think of anything else I can try?
