Ok so I have been noticing that when I pour a beer 2 thirds will be foam and 1 third beer... yes I'm opening picnic tap all the way and tilting glass. I'm running like 8 psi. And after the first pour of the night the foam is worse..... Also I am noticing air in the beer line coming out of the keg after it sits a wile.. I have 3 kegs 1 from more beer and 2 from some place I can't remember they all ball lock... what do I do I'm tired of waiting for the foam to settle to drink
