proud owner of a new kegerator system! hopefully going to start kegging my home brew, for now just commercial kegs. my question, after a night of sitting, when i pour a beer it is very foamy. is this normal after sitting under pressure for a while or not? the pressure going out to the keg is about 5-8 psi.

A longer serving line may help. I like to have a few feet as a minimum. Maybe up to four or so in your case.
