Let faucets run at a trickle overnight during extremely cold weather. It costs only pennies, and the moving water will help prevent the pipes from freezing.

Wrap and insulate all water pipes in unheated areas, such as your basement. Pay close attention to pipes near exterior walls, especially in kitchens and bathrooms.

Identify the location of the shutoff valves for your water supply, usually near the water meter. In emergencies, use the house-side service valve to shut off your water supply.

Keep the water meter area above 40F. Freezing temperatures can break the meter. If it becomes damaged, homeowners are responsible for fixing it.

Repair or replace broken exterior windows. Cover windows with plastic and caulk windows near water meters and pipes. When cold air blows on a pipe, it increases the risk of freezing.

Disconnect garden hoses and shut off the outdoor water supply. Most outdoor faucets have a dedicated shutoff valve inside. Use that, and leave the outside faucet open to drain the pipe.
