2, What is the best method of preventing "end of tank dump"? I bought a 5lb tank, as well as a 2.5lb tank for use during fill time. I had heard to check daily on the high side for slowly dropping pressure, is this the best way?
3, Should the tank be purged completely after disconnecting it when the bottle needs to be filled? Or will that happen when the bottle is filled? Does it need to be completely empty before filling?
