For the record, I am using some storebought kegs, but figure you guys know more about all of this than I do. EDIT: I checked the internet and the couplers to the keg are of the sanke variety.
Here's the deal: I have a two tap kegerator and the aggressive amount of foaming is wrecking my beer drinking experience. I've got the CO2 set to the lowest setting the regulator will allow (4psi) and it's kicking out SO much foam, I am unsure what to fix now.
I haven't run the tubing in the kegerator very elegantly. But I am opening the tap as fast as possible and doing everything else you would (glass angle, etc.) But the foam that fires out of the tap right now is just so... aggressive.
