Jockey Box 1 of 2 Lines is Foamy

[Bunzmon]

Hi,

I have a barely used jockey box with a cold plate. Every time I use it 1 line is foamy and the other line is a bit flat. My psi is at 19. I had the lines professionally clean and he said everything checks out. Any ideas?

Thanks for the help.

Make sure the plate is on a rack and not on the bottom of the cooler, make sure the drain is open on the cooler to let the water out. Make sure the kegs are 50 degrees or less. Set your pressure between 26-28 lbs., make these adjustments and it should straighten you out
