Gas in Beer Line

[Holden4th]

Every now and then, when I change over a keg, I get a very frothy pour. This is despite the fact that the previous keg poured perfectly and I haven't changed the gas pressure. This time, when I pull the handle I get a blast of gas then a frothy pour. I can see gas pockets and bubbles in the beer line. What do I do about this to prevent it happening again?

I’d say that your new (full one) keg has a little bit of air/gas in the pickup tube and once you connect it the air/gas goes to the highest point in the tubing. Not sure what you could do to prevent it, maybe pre prime the pick up
