The problem with only blowing out lines is the way the lines run in some units, you do not get 100% of the water out of a system when you blow the lines. The remaining water can pool in a low spot and freeze and crack a line or fitting. If you are in an area that gets and stays below freezing for some time, the extra 15 minutes and few dollars for the pink stuff is great peace of mind.
