Drip your faucet. Just a small drip or stream can be enough to help prevent damage.
Open the cabinet doors beneath your sink so room temperature air can warm the pipes
.Make sure your heat is on, even overnight. Your heating costs may go up, but the damage from a burst pipe is worse
.Cover outdoor faucets with something protective. Add more insulation to attics, basements and crawl spaces.
Frost on your pipes could mean that they are frozen. If your faucet has a small amount of water coming out or none at all, it is also likely frozen.
