A burst pipe in winter can cause thousands of dollars in water damage within minutes. Knowing how to prevent frozen pipes and what to do if one bursts can save you time, money, and stress. Here’s a step-by-step guide to protecting your home from plumbing disasters.
How to Prevent Pipes from Freezing & Bursting
1. Insulate Vulnerable Pipes
• Where to Focus: Basements, crawl spaces, attics, and exterior walls
• Why It Matters: Proper insulation helps maintain a stable temperature and prevents freezing.
• Tip: Use foam pipe insulation, heat tape, or fiberglass wrap on exposed pipes.
2. Let Faucets Drip During Freezing Weather
• Why It Matters: Running water prevents pressure buildup that can cause pipes to burst.
• Tip: A slow, steady drip from both hot and cold taps works best.
3. Keep the Heat On (Even When Away)
• Recommended Temperature: At least 55°F (13°C)
• Why It Matters: Cold indoor temperatures increase the risk of frozen pipes.
• Tip: If traveling, open cabinet doors under sinks to allow warm air to circulate.
4. Seal Drafts and Close Garage Doors
• Where to Check: Cracks around windows, doors, and where pipes enter walls
• Why It Matters: Cold air infiltration makes pipes more susceptible to freezing.
• Tip: Use caulk or spray foam to seal gaps, and keep garage doors closed if pipes run through the space.
5. Drain Outdoor Faucets and Sprinklers
• Why It Matters: Water left in exterior plumbing can freeze and expand, leading to bursts.
• Tip: Shut off outdoor water valves and use an air compressor to clear sprinkler lines.
What to Do If a Pipe Bursts: Step-by-Step Damage Control
1. Shut Off the Water Immediately
• Locate the Main Water Valve: Typically found in the basement, garage, or near the water meter.
• Why It Matters: This stops the water flow and minimizes flooding.
2. Turn Off Electricity if Water Is Near Outlets
• Why It Matters: Water and electricity are a dangerous combination.
• Tip: If water reaches outlets, turn off power at the breaker before entering flooded areas.
3. Drain the System
• How: Open all faucets (both hot and cold) and flush toilets
• Why It Matters: Draining pipes relieves pressure and prevents additional damage.
4. Contain the Leak
• What to Use: Towels, buckets, or a wet/dry vacuum to remove standing water
• Why It Matters: Quick action can prevent severe water damage and mold growth.
5. Temporarily Seal the Pipe
• Quick Fixes: Use pipe repair tape, a rubber patch with hose clamps, or epoxy putty
• Why It Matters: A temporary fix can buy time until a plumber arrives.
6. Call a Plumber for Repairs
• When to Call: If the burst section is large or if you need professional pipe replacement
• Tip: Know a trusted plumber before an emergency happens to avoid delays.
7. Dry Out the Area Quickly
• Best Tools: Fans, dehumidifiers, and open windows (weather permitting)
• Why It Matters: Drying prevents mold and structural damage.
The Bottom Line: Be Prepared Before Winter Hits
Preventing frozen pipes is much easier than dealing with a burst one. Take proactive steps to insulate, drip faucets, and maintain indoor temperatures. If a pipe does burst, acting fast can limit the damage and save thousands in repair costs.
