Protect pipes from freezing this winter
Freezing pipes are a concern for homeowners who live in cold climates. When temperatures dip below freezing, the risk that pipes will freeze rises. Should a pipe burst, the damage that results can be extensive and costly.
Any pipe can freeze, but those that are directly exposed to the cold are the most vulnerable. These include pipes that feed outdoor hoses, swimming pool supply lines, pipes in unheated indoor rooms (i.e., basements or garages), and any pipes that run close to the outdoors through uninsulated walls. Water expands as it freezes, and that expansion can place pressure on whatever is trying to contain it — including pipes.
To avoid serious damage, homeowners need to prepare for the arrival of colder weather and be smart about how they protect pipes.
• Drain water from swimming pools and water sprinkler supply lines prior to the onset of cold weather. Drain water before freezing temperatures arrive, and don’t forget to drain outdoor garden hoses and store them inside after watering season has come and gone.
• Close indoor water valves that feed outdoor spigots/bibs. Open the spigot outside to allow water to drain out. Keep the outside valve open so that any water that has accumulated will continue to drain and expand outward without damaging the pipe. An insulated bib dome also can help prevent frozen pipes.
• Open cabinet doors to allow heat to reach pipes inside of cabinets. Keep the doors open to spaces that may not be heated or insulated as well as other areas of the home so that heat can find its way inside. Consider wrapping these pipes with an insulating material as well, such as heat tape or pipe sleeves.
• Maintain a consistent thermostat temperature. Ensure the temperature inside your home does not drop below 55 F; otherwise, problems can arise. Use a programmable thermostat to keep the house comfortable even when you are not home. Individuals who are traveling should set the thermostat so that it will keep the home at the recommended temperature to avoid frozen pipes.
• Open one faucet. When it is very cold outside, particularly at night, let water slowly drip from one faucet to prevent freezing. Choose the sink that is furthest from where water enters the house so water is flowing through all of the pipes to reach that faucet.
• Increase insulation around where pipes enter the house. Use insulating foam to seal any drafts where pipes enter the house from the outdoors.
Frozen pipes cannot always be avoided. Therefore, it is important that everyone in the household knows how to shut off the main water valve in the event a pipe bursts. This can prevent expensive damage to a home.
