I thought my keg was empty and it was close but when I opened it up to clean it seemed there was maybe two beers or 1 and a half left. My son said he tried to pour while I was traveling and couldn't get anything.
So I tried, cranked the pressure up some and tried again. Nothing. So I went ahead and opened it dumped the little remains and put some water and pbw in and shook it up. So then I reconnected the gas and found again it would not flow, so I cranked up to about 15 psi and it started slow then resumed normally. I did not notice anything coming out that looked like sludge.
Just curious if there is some actions I should take if / when this happens again?
When I dumped it the inside looked clean as a whistle. It was a dead ringer IPA so there were lots of hops involved.
Not sure where the problem was, I do use a picnic tap with about 5 ft of beer line which I had left connected while I was gone.
