Winterizing Plumbing: Essential Seasonal Maintenance Tips
Protect your plumbing system from winter damage with expert seasonal maintenance advice. Learn how to prevent frozen pipes and keep your water heater running efficiently.
Critical Winter Preparation Steps
Insulate Exposed Pipes
Wrap pipes in unheated areas with foam insulation or heating tape.
Pipes in basements, crawl spaces, garages, and exterior walls are most vulnerable. Use pipe insulation sleeves, heat tape, or pipe heating cables. Pay special attention to pipes near exterior walls.
Seal Air Leaks
Close gaps around pipes, vents, and electrical outlets with caulk or foam.
Cold air can seep through small gaps and freeze pipes. Check around water supply lines, dryer vents, electrical outlets, and where pipes enter the house. Seal any gaps larger than 1/4 inch.
Drain Outdoor Faucets
Disconnect hoses and drain water from outdoor faucets and sprinkler systems.
Close the indoor shut-off valve for outdoor faucets, then open the outdoor faucet to drain remaining water. This prevents freeze damage to outdoor plumbing lines.
Service Your Water Heater
Schedule annual maintenance and consider installing a water heater blanket.
Winter increases water heater workload. Annual maintenance includes flushing sediment, checking the heating element, and testing safety valves. Insulation blankets can improve efficiency by 7-16%.
