This was on TechTalk and it is a very good video. I started using a process like this based on Peter's advice, the the video has some great tips for sanitizing the line, working with pressures, etc. The tip to use a autosiphon on the line for cleaning and sanitizing is a great tip, one that I will start using immediately.
