Check vulnerable locations before cold weather
Water lines near exterior walls, unheated spaces, and drafts are more exposed to freezing. Ask a plumber about suitable insulation and address air leaks with an appropriate building professional. Insulation reduces heat loss but does not create heat.
Keep the home heated and valves accessible
Maintain appropriate indoor heat during winter absences and arrange for someone to check the property. Locate the main water shut-off and ensure it is accessible. Follow your insurer’s requirements for an unattended home.
Do not thaw a pipe with an open flame
A torch or high heat can damage materials and create a fire risk. If a pipe may be frozen, use safe ambient warmth and get professional advice. A pipe can split while frozen and leak when water begins to flow again.
Treat a thawing leak as an active supply problem
If water appears as the line warms, turn off the supply if safe and call. Keep away from water near electrical equipment. A repaired section may also need a plan to prevent the same freezing condition from recurring.
Discuss your specific plumbing concern
General guidance cannot diagnose your property. Learn about the relevant plumbing service, or send a service request with your location and symptoms.
