Tip 1: Wrap your pipes in heat. The important feature is the exterior piping. If the cold-water pipes touch the exterior portion of the building, when the water isn't being used and the temperature is very cold, most likely the pipes will freeze. The only time water won't freeze is when it's moving, so it's is a good idea to leave all the faucets open while you're away from home for any length of time. The best thing you can do, however, is insulate the whole space.
