I used to only blow out the lines but I only did that for one year, I had to replace a lot of water lines that froze and burst. Now I blow out the lines and use rv freeze in the lines. they hake a rv anti freeze valve and you can place it on the pump intake and it only takes less then a gallon of rv anti freeze to winterize your RV. with the valve left in place there is an on/off built in valve, sure makes winterizing a lot easier.
