Ive been having nothing but trouble pouring beers from the tap. I recently built my kegerator that contains my co2 tank, kegs and lines. The taps run through the door, and everything is at 41 F inside. I have 10ft plastic lines, the typical ones u get from brew and grow, and no matter what I do, half or more of my glass is foam. I've tried serving at 8, 9, 10, all the way through 15 psi, and always get foam. It seems like I have lots of gaps in my line without beer, any easy way to remedy this? Sry for having one long paragraph, I'm posting this from my phone.
