Freezing temperatures are on the way. To help prevent frozen pipes, make sure to keep cabinets open where water lines have external wall exposure.

Maintain a water drip to keep water moving on faucets inside your home.

Add pipe foam insulation to exposed pipes in unheated areas like the attic, basement, or garage to provide a buffer against the cold.

Disconnect water hoses from external faucets

Crawl space – close vents
