I was having dispense foaming issues with my kegs; I have the correct line diameter, length & CO2 volumes for balanced kegs, but lots of foam lately. I did some searching online, and found this video about maintenance on the Perlick 525 faucets that I use:
After viewing the video, I disassembled mine and found the distorted O-ring that he mentioned, the #2 in this image:
Sure enough, that O-ring was stretched and distorted quite a bit, probably from me over tightening the #7 cup that it resides in. I figured "tighter must be better", but that's not the case. I suppose air was being introduced during the pour, causing foaming.
I found the right size O-ring at my local ACE Hardware, lubed it and any other O-rings with a light coating of keg lube, and I now have a really nice pour with perfect foam.
