Foaming on 1 line of 3 line system
I have 3 lines in a glycol pump system and appear to have problems with one of the lines. The keg pours great and then suddenly goes to complete foam. It never recovers no matter what I try. The other two lines seem balanced and work fine. When I switch the line to another keg, sometimes it works fine. It appears this line will "corrupt" a keg and then I can't get rid of the foam. I've already replaced all taps. Do I have a bad coupler? What is the proper way to clean a coupler? Any ideas? Thanks.
