Okay, so we've changed regulators on each cylinder, increased pressures, and switched out the old blender with a new one. Each seemed to help a bit, but it still was a noticeable problem. On one side of our cooler we have 3 nitro beers that were all sharing the same regulator. After about 20 minutes of pulling out t fittings and hooking each nitro beer up to its own regulator, the problem seemed to be eliminated. whew! I'm not out of the woods yet, since the problem would come and go, but I think that since the beer that was pouring bad today did a complete 180 after putting it on its own regulator, I think I may have found the culprit. I'll give it a couple of days and if the problem doesn't resurface, I know that it is solved.
So, I ask: Could the problem have been the regulator in that it couldn't keep up with all three of the nitro beers that were running together?
Thanks for your replies, and hopefully we won't have this problem again. It was pretty frustrating to serve Guinness, what we are known for, and have it come out like crap. But, I think we're past that.
