How to Prevent Frozen Pipes This Winter: A Complete Guide

Every winter, thousands of Minnesota homeowners deal with the nightmare of frozen and burst pipes. The good news? Most frozen pipe disasters are preventable with proper preparation.

Why Pipes Freeze

Water expands as it freezes, creating tremendous pressure inside pipes. When this pressure exceeds the pipe's strength, it ruptures. Even a small crack can release hundreds of gallons of water.

High-Risk Areas in Your Home

• Exterior walls with plumbing
• Unheated basements and crawl spaces
• Garages with water supply lines
• Kitchen cabinets on exterior walls
• Outdoor hose bibs

Prevention Steps

Before Winter Arrives

• Disconnect garden hoses - Water left in hoses can freeze back into the pipe
• Shut off outdoor faucets - Use the interior shut-off valve and drain the line
• Insulate exposed pipes - Use foam pipe insulation or heat tape
• Seal air leaks - Check for gaps around pipes where they enter your home
• Know your shut-off valve location - Be ready to act fast if a pipe bursts

During Cold Snaps

• Let faucets drip - Moving water is less likely to freeze
• Open cabinet doors - Let warm air reach pipes under sinks
• Maintain heating - Keep your home at least 55°F, even when away
• Use space heaters carefully - In problem areas like crawl spaces

What to Do If Pipes Freeze

1. Keep the faucet open - As ice melts, water needs to flow
2. Apply heat to the frozen section - Use a hair dryer, heating pad, or towels soaked in hot water
3. Never use open flame - Torches can damage pipes or start fires
4. Check all faucets - If one is frozen, others might be too
5. Call a plumber if you can't locate or thaw the frozen section
