Winter brings cold temperatures that can cause serious damage to your plumbing system if you are not prepared. Frozen pipes can burst, leading to costly repairs and water damage. Taking steps to protect your plumbing before the cold sets in can save you time, money, and stress.
Inspect and Insulate Exposed Pipes
Pipes located in unheated areas such as basements, attics, garages, and crawl spaces are most vulnerable to freezing. Inspect these pipes for damage or leaks, then wrap them with foam pipe insulation sleeves or heat tape.
- ▸Use foam sleeves for pipes up to 1 inch in diameter.
- ▸For irregular shapes or tight spaces, heat tape or heat cables work better.
- ▸Secure insulation with duct tape or zip ties to avoid slipping.
Drain and Shut Off Outdoor Water Sources
Outdoor faucets and irrigation systems are common points of failure in winter.
- ▸Shut off the water supply to outdoor faucets from inside your home.
- ▸Open the outdoor faucet to drain any remaining water.
- ▸Use insulated faucet covers to protect the spigot.
- ▸Drain sprinkler systems completely or have a professional blow out the lines.
Keep Indoor Water Flowing
Even a small drip can prevent pipes from freezing by keeping water moving.
- ▸Let cold water drip slowly from faucets served by vulnerable pipes.
- ▸Open cabinet doors under sinks to let warm air circulate.
- ▸Keep indoor temperature above 55°F (13°C), especially in rooms with plumbing.
Seal Gaps and Cracks Around Pipes
Cold air can enter through gaps around pipes. Use caulk or spray foam to seal small openings, weatherstrip nearby doors and windows, and add insulation where needed.
Prepare Your Water Heater and Heating System
- ▸Drain a few gallons from your water heater to remove sediment.
- ▸Set the water heater thermostat to at least 120°F (49°C).
- ▸Have your heating system serviced before winter.
