Check exposed plumbing before freezing weather.
Disconnect outdoor hoses and address exposed pipes in unheated spaces. Protecting a pipe from cold air and maintaining appropriate heat are different from repairing a pipe that has already frozen. Ask about vulnerable areas during a planned visit.
Plan for time away.
Arrange for someone to check your home if you will be away, and make sure they know how to contact you and where the accessible main shutoff is. Ask a qualified professional about a property-specific winterization plan rather than draining systems without understanding appliances, heating, or fire-protection connections.
Watch for a change in water flow.
Reduced or absent flow during freezing conditions is a reason to investigate. A frozen pipe can be damaged even before water appears, and a leak may become visible as it thaws. See frozen-pipe service and keep the shutoff accessible.
Never use an open flame.
Do not use a torch or open-flame heater to thaw plumbing. Keep electrical equipment away from water. If the affected pipe is inaccessible or you cannot safely act, call for help. The American Red Cross frozen-pipe guide explains prevention and safe precautions.
If a leak starts
Isolate the supply only if safe, stay away from water near electricity, and call to describe the break. Our first steps for a water leak explains what information helps the repair visit.
