I'm sure this question has been raised but I couldn't find an answer for my situation anywhere else.
When I pour a glass from my keg it is all foam. after letting it sit for a while I end up with 1/4 a glass of beer, which is about 3/4 less than I wanted
My kegerator is 38F and my beer line is 5 ft of 3/16 ID line. The line isn't attached to the tower, just a picnic tap inside. When I keg I hit it with 20psi of co2 for two days then drop it down to 10psi for five more days. The problem doesn't seem to be too bad for the first week, only half a glass of foam, but as the level drops it gets worse. Almost forgot...after pressurizing for a week I bleed the excess co2 before the first pour, and again when the foam started getting really bad.
Any help would be greatly appreciated!
