The problem with just blowing out the lines is that there is always a low point in one of the lines to trap water. No matter how much air you put through it, you will always have water left in a line somewhere. Do it right with RV antifreeze and you will have no worries. $6 worth of antifreeze is better than ripping apart a wall to try and find a ruptured line!
