This is my first go at kegging and so far it’s not going well. When I pour it’s all head and it spits air half way through then more foam, if I pour a second one right away, that one pours perfect. After I pour I can actually see little bubbles coming from the keg into the line after the pour and there is always an air pocket. I tried more pressure stepping it up all the way to 18psi, but that made things worse. I’ve gone as low as 10psi with no noticeable difference. I am running at 12psi with 5mm ID EVABarrier tubing at 8ft. Kegerator is set to 40F. All connections are Duotight with no leaks. Any ideas?
