I know we have all had the occasional problem that defies all that we were taught or learned through experience. I have a doozie that I could use some ideas or suggestions on how to fix.
I have an account that started with a 6 faucet(DS-256-PSSKR) remote system. A little more than a year later, another 6 faucet tower installed. Now this is not even a bar, it is a pizza shop that is selling craft beers with meals and growlers to go. They are doing quite well with this.
Now to the problem. a few months into the second tower, we started having a foam issue on the new tower occasionally. All of the beers on the new tower ran fine except for the Yuengling Lager. I was called in to check it out. Did a few things to make it work, (new coupler one time, tweak pressure another time, etc.) Every time I would do something, it would be okay for a while. Then it would act up again. One time the keg storage was 33 deg., so I suspected over carbonation. Changed the temp to 38 an all was well again . At least for a little while.
I have been working on tap systems for a long time (29 years) and there is not too much that I haven't seen over the years, but this one has me stumped, baffled and frustrated.
Details:
Cooler temp 38, Glycol temp 30. 4301-ep power pack, (2) 30' 6 product 5/16 trunk lines. (2) ds-256-psskr towers. McDantim 60/40 blender. High volume CO2 and Nitro regulators. Separate secondaries for each keg set at 20.
10' from floor to faucet. 17+/- lbs built in restriction( depending on whose restriction values that you use), 2 lbs push pressure. I tried turning the pressure down to 16 lbs and up to 22 lbs. with no change in foaminess.
Now the frustrating part.
Yuengling Lager once again is foamy, I do all the standard troubleshooting. Nothing is coming up wrong.
I swap Miller Lite and Lager, Lite is fine through the Lager tap (coupler all the way through to the faucet). Lager is crappy through the Lite tap. I disconnect Lager and connect Coors Light to that tap and it runs perfect. I reconnect Lager and it is crappy. Logic says bad Lager keg. Wrong. I pour the lager keg in the walk in and it runs perfectly.
Next I swap The Lager with Blue Moon from the original tower and Lager runs like a top, clear as a bell. Blue Moon now runs like crap on the new tower. I now swap Lite with the Blue Moon and Lite is fine out of the other faucet, and Blue Moon is crappy still. I even went as far as switching the direction that that glycol flows. I know that the farthest tower should be first and then the closer one. Both are 30' away,(same walk in) with the towers right next to each other. It shouldn't matter but thought I would give it a shot.
Anyone have any ideas on what else to check,or something that missed, before I pull out what is left of my hair.
My fried brain thanks you,
