Why Do Pipes Burst? Causes, Prevention, and Solutions
Understanding what causes burst pipes is essential for every property owner. A burst pipe can lead to unexpected water damage, costly repairs, and significant stress. But what causes pipes to burst, and how can you prevent it?
In this guide, we’ll explain the common causes—like freezing temperatures, high water pressure, corrosion, and clogs—and offer actionable tips to protect your property.
Common Causes of Burst Pipes
1. Freezing Temperatures and burst pipes
Cold weather is the most common reason for burst pipes. When water freezes, it expands, creating pressure inside the pipe walls. This pressure can cause cracks or complete ruptures.
How It Happens:
• Water turns to ice when temperatures drop below 32°F (0°C).
• Ice expands, increasing pressure until the pipe bursts.
Prevention Tips:
• Insulate exposed pipes in unheated areas (e.g., basements, attics).
• Keep your thermostat set to at least 55°F during cold months.
• Drain outdoor faucets before winter.
2. High Water Pressure
Excessive water pressure is a silent threat that can weaken pipes over time. Most plumbing systems are designed for pressures between 40–60 psi. Anything above this range can strain pipes, joints, and fixtures.
Signs of High Water Pressure:
• Banging or knocking noises in pipes.
• Leaking faucets or fixtures.
• Appliances like washing machines wearing out quickly.
How to Prevent:
• Install a pressure regulator or pressure-reducing valve.
• Regularly check your water pressure with a gauge.
3. Pipe Corrosion
Corrosion occurs when metal pipes react with minerals and chemicals in the water. Over time, this weakens the pipe walls, making them more prone to bursting.
Factors That Accelerate Corrosion:
• Hard water with high mineral content.
• Old pipes (galvanized steel or iron are especially susceptible).
Prevention Tips:
• Replace outdated pipes with corrosion-resistant materials, like copper or PEX.
• Install water softeners if your home has hard water.
4. Clogs and Blockages
Clogs can restrict water flow, causing pressure to build up behind the blockage. If the pressure becomes too high, the pipe may burst.
Common Causes of Clogs:
• Hair, soap scum, and grease buildup.
• Tree roots invading underground pipes.
• Mineral deposits from hard water.
Prevention Tips:
• Use strainers in drains to catch debris.
• Schedule regular plumbing maintenance.
• Avoid flushing non-degradable items down the toilet.
How to Prevent Pipes from Bursting
1. Insulate Pipes: Use foam insulation or heat tape on pipes in unheated areas.
2. Maintain Proper Water Pressure: Regularly check your water pressure and ensure it stays within safe levels.
3. Perform Regular Inspections: Look for leaks, discoloration, or reduced water flow. Replace old or damaged pipes promptly.
4. Drain Outdoor Faucets: Disconnect hoses and drain outdoor faucets before freezing temperatures arrive.
5. Keep a Consistent Indoor Temperature: Even when away, set your thermostat to prevent freezing.
What to Do If a Pipe Bursts
Despite preventive measures, pipes can still burst. Quick action can minimize damage:
1. Turn Off the Water: Shut off the main water supply immediately.
2. Drain the System: Open all faucets and flush toilets to remove water.
3. Call a Professional: Contact a licensed plumber and a certified water damage restoration company.
4. Remove Standing Water: Use towels, mops, or wet/dry vacuums. For extensive damage, hire water remediation specialists.
5. Document the Damage: Take photos for insurance claims.
Prevent Mold and Mildew After a Burst Pipe
After water damage, it’s crucial to dry the area thoroughly to prevent mold growth. Use fans, dehumidifiers, and open windows to improve airflow. In severe cases, contact a restoration expert for professional drying and cleanup.
