Excessive Foaming

[FloydCountyBrew]

Need some professional advice. We have excessive foaming issues on our downstairs tap. We run two beer lines from a splitter at the bottom of each serving vessels. The upstairs line flows just fine. The downstairs line however must go up and down and the outside across a very long run. A big portion of it must run outside, which we have insulated it with glycol chilled lines. The beer comes out of the downstairs taps at a cold temp however it has sporadic burst of foam and continued excess foam that is very dense and doesn't want to dissolve back into beer. Oddly, we see gas bubbles as soon as the downstairs beer line leaves the splitter just below the serving vessel. We have seven tank set ups just like this diagram. Oddly One of the tanks set up does not foam nearly as bad and it doesn't have the same amount of gas bubbles in the line. We've tried flow control taps and they do not seem to help us. We use a centralized CO2 system that feeds CO2 into the top of each serving vessel. Any suggestions are welcome

Install air or CO2 driven beer pumps with a regulator to control pressure.

Your draft system is balanced for the direct draw taps but not the long draw. The pressure drop in the long lines is far too much for the co2 to stay in solution. Pneumatic beer pumps could help, they will boost the line pressure, but having a properly designed draft system is probably going to be the best solution. It is tricky to have both a long and direct draw with elevation differences balance perfectly on both ends, but it is doable, we have a local pub that does the same thing, no foaming issues.

We installed a long draw system and it's not as easy as 1,2,3. We the same problems. We installed pumps which helped but in the end had to call a draft company in. The biggest issue that need to be corrected was the installation of an inline reducer. You have to have a certain amount of feet of reducer per line foot.

Appreciate the tips. Actually Drinkswell a Local company installed. But it's never worked properly.
