So, I have had a kegorator, converted from a fridg, for a couple of years. I went through about 6 commercial sanky kegs and all of sudden the last two kegs have been super foamy. I can only pour about a third of a glass. They only thing that I can tell that is different from before is that I made a bonehead move when I cleaned the system before the first foam keg. I forgot to tighten the hose to the top of the coupler before taping the keg. Besides the mess and the embarrassment I didn't think it was a big deal. The last two kegs have been from two different breweries, so I don't think it was a keg issue. Q: could the beer being blown out cause some part of the coupler to break that could cause the foam? The crazy thing is it worked fine for 6 kegs, so it is not hose length balancing or my pouring ability. I am testing the temp and the regulator for accuracy since I have always had it at 10 psi and don' think I turned the fridge temp up. I have also taken the faucet apart to make sure I put it together right. I am at a bit of a loss.
You are getting foam because your system is out of balance . . . some combination of pressure/carb-level/temp/hose-length. Symptoms point to your new keg being carb'ed at a higher level than previous, if you'll reply with what type beer(s) and temp we should be able to help.
A loose hose can cause foaming issues. I was bottling off a Sanke and didn't tighten down the CO2 nut on the coupler enough and the bottles were all foam. Tightened it up and had no issues with that keg foaming or any of the other 6 kegs I bottled from that day.
