Is there any reason why kegs would require higher head pressure for serving when compared to brite tanks?
We serve standard ~2.5 volume dissolved co2 beers directly from brites under 13psi and have no issues with foaming at the tap. Once those brites are low enough, we keg the rest off and serve the remainder from those kegs. However, for some reason we cannot serve those kegs under the same pressure - 13psi. They foam continually at the tap until the head pressure is increased to something like 18psi.
We have a long draw and we also push upstairs from the basement. We have beer pumps and FOBs on every keg line. The differences between the tank and the keg line are the FOB and maybe 8 extra feet of 3/8" beer line. The run from the FOB to the pump varies, but is no more than 30 feet.
I understand how to fix the problem, but it's a band aid. Slower selling brands are picking up more co2 while they sit under the increased pressure. I can't gather why serving one beer from two different vessels won't work under the same head pressure. I've tried bypassing the FOB, I've tried different brands of couplers, and I'm running out of ideas.
Any help is much appreciated!
