Whenever freezing temperatures are forecast, one must make the necessary preparations around the house to keep the cold air out. One important thing to do is to make sure your pipes do not freeze. There are a few ways you can prevent frozen pipes. The first is letting your faucets drip. This may not sound good for your water bill, but it will keep the pipes from freezing. Leaving the cabinet doors open and insulating the pipes will also keep them from freezing.
