Common Causes of Burst Pipes and How to Prevent Them

Updated: Jul 30



Burst pipes can cause significant damage to your property and create a considerable financial burden. Understanding the common causes of burst pipes and how to prevent them is essential for homeowners and property managers. In this blog, we'll explore the typical reasons for burst pipes and provide detailed prevention strategies to help you avoid this costly problem.


Common Causes of Burst Pipes

Freezing Temperatures

Freezing temperatures are among the leading causes of burst pipes, especially in colder climates. If the pressure becomes too great, the pipe can burst, necessitating burst pipe repair. When the temperature drops, the water inside the pipes can freeze. As water turns to ice, it expands and increases pressure within the pipe. 


Corrosion and Rust

Over time, corrosion and rust can weaken pipes, making them more susceptible to bursting. Older homes with aging plumbing systems are particularly at risk. Corrosion can occur due to the chemical composition of the water, including its pH and mineral content.


High Water Pressure

While high water pressure might seem like a minor issue, it can cause significant damage to your plumbing system. Excessive water pressure strains pipes and fixtures, potentially leading to cracks or bursts. The standard water pressure for most homes is between 40 to 60 psi (pounds per square inch). Anything beyond this range is considered high and can compromise the integrity of your pipes.


Clogged Pipes

Clogs within your pipes, caused by various materials such as hair, grease, or debris, can cause a buildup of pressure. If the pressure becomes too high, it can result in a rupture. Regular maintenance and proper waste disposal can help prevent clogs.


Tree Root Intrusion

Tree roots are naturally drawn to the moisture found in underground pipes. Root intrusion can lead to pipes cracking or breaking as the roots grow and apply pressure. This problem is common in older homes with clay or concrete pipes.


Poor Installation

Ensuring that your plumbing system is installed by qualified professionals can mitigate this risk and recognize indications of immediate plumbing services requirements. Improper installation of your plumbing system can result in weak joints and fittings, increasing the risk of bursts. 


Ground Movement

Ground movement caused by natural events such as earthquakes, shifting soil, or heavy construction nearby can cause pipes to move and break. While this is less common, it can still be a significant factor in certain areas.


How to Prevent Burst Pipes

Insulate Your Pipes

One of the most effective methods for preventing pipes from freezing and bursting is to insulate them. Use foam insulation sleeves or heat tape on pipes located in unheated areas like attics, basements, and crawl spaces. This extra layer of protection helps to maintain the temperature inside the pipes, even when the outside temperature drops.


Maintain a Steady Temperature

Maintaining a consistent indoor temperature, especially during the colder months, is crucial. Keep your thermostat set to at least 55°F (13°C) even when you are away from home. This helps ensure that pipes do not freeze.


Seal Leaks and Openings

Inspect your home for any cracks or openings near pipes. These can let in cold air, increasing the risk of freezing. Use caulk or insulation to seal these gaps and prevent cold air from affecting your pipes.


Keep Faucets Dripping



During extreme cold spells, allow a slight drip from your faucets. Running water is less likely to freeze. This small trickle can relieve some of the pressure within the pipes and prevent them from bursting.


Install a Pressure Regulator

A pressure regulator can ensure that your home’s water pressure remains at a safe level. This device reduces the risk of high water pressure that can damage pipes. If you are unsure about your home’s water pressure, consider having it checked by a professional plumber.


Monitor Your Water Hardness

Understanding the mineral content and hardness of your water can help in preventing corrosion. Water softeners can be installed to reduce the levels of minerals like calcium and magnesium that contribute to corrosion and rust in pipes.


Regular Inspection and Maintenance

Regularly inspect and maintain your plumbing system. Look for signs of wear, corrosion, or potential issues. Early detection can save you from extensive damage, including signs you need experts for water heater problems. Schedule annual check-ups with a professional plumber to ensure everything is in good condition.


Safe Landscaping Practices

Plant trees and shrubs away from your home’s sewer lines and water pipes. Be mindful of where roots can grow and potentially cause damage. If you're planning to plant new trees, make sure to choose species with less aggressive root systems and position them at a safe distance from underground utilities.


Proper Waste Disposal

Never pour grease, oil, or other substances that can clog pipes down your sinks. Use a strainer to catch hair and debris in bathroom drains. Educate all household members about proper disposal methods to prevent clogs and potentially burst pipes due to pressure buildup.


Ground Movement Precautions

If you live in an area prone to earthquakes or soil movement, consider installing flexible pipe connectors. These connectors can absorb some of the movement and reduce the risk of your pipes bursting.


Upgrade Old Plumbing Systems

If you live in an older home, consider upgrading your plumbing system. Replacing old, corroded pipes with new, more durable materials can significantly reduce the risk of bursts. Consult with a professional plumber to assess the condition of your current system and recommend any necessary upgrades.


Install Leak Detectors

Installing leak detectors in key areas around your home can provide early warnings of pipe issues. These devices can alert you to small leaks before they become significant problems, allowing you to address them promptly.


Conclusion

Preventing burst pipes is an essential responsibility for homeowners and property managers. Understanding the common causes, such as freezing temperatures, corrosion, high water pressure, and improper installation, is the first step in safeguarding your property. By implementing preventive measures like insulating pipes, maintaining a steady temperature, conducting regular inspections, and practicing safe landscaping, you can significantly reduce the risk of burst pipes and the extensive damage they can cause.

Remember, proactive maintenance and early detection are vital. If you suspect any issues with your plumbing system, it's always wise to consult with a professional plumber to ensure the safety and longevity of your pipes. Investing time and resources into prevention today can save you from substantial repairs and headaches in the future.
