What causes pipes to freeze and burst?

Why Pipes Freeze: Understanding Freezing Temperatures

Pipes are prone to freezing and bursting when temperatures plummet to 20°F or below due to the expansion of water within them. At these frigid temperatures, water inside your pipes expands as it turns to ice, causing tremendous pressure on pipe walls. If this pressure becomes excessive, the pipe can burst under the strain.

Blacktown’s winters are generally mild, with temperatures infrequently reaching freezing levels. However, water pipes freezing in certain areas of your home remains a risk during an unusual cold snap. Pipes located in certain vulnerable areas of your property, such as on an exterior wall or in uninsulated basements, attics, and crawl spaces, are the ones likely to freeze.

Water expands by over 9% upon freezing, which increases pressure inside pipes leading to potential bursts if the ice pushes forcefully against the pipe walls. Copper and PVC pipes freeze burst at pressures exceeding 1,000 pounds per square inch.

To effectively prevent your pipes from freezing:

• Insulate pipes in unheated areas
• Seal cracks and holes near water pipes, which can permit cold air that enters your home
• Drain water from your drain line and sprinkler/irrigation lines before winter
• Letting your faucet drip during freezing weather is advisable
• Maintain adequate heating to protect your water pipes at risk within your home

If you find a frozen pipe, it’s imperative to immediately shut off your main water valve. Never do use an open flame to thaw pipe sections frozen by cold weather, as this can cause a fire hazard. Instead, use a hair dryer or space heaters to gently heat the frozen area of the water pipe allowing trapped water to escape.

Where Pipes Are Most Vulnerable to Freezing

Pipes located in unheated areas like an attic crawl space and along the exterior walls are often guilty of permitting cold air into your home. The risk extends to potential pipe freezing in areas such as:

• Uninsulated exterior walls
• Attics
• Basements
• Crawl spaces
• Garages
• Sheds

Outdoor water supply lines, such as hose bibs and sillcocks, are also highly susceptible to freezing temperatures:

• Hose bibs and sillcocks
• Irrigation systems
• Pools equipment

In commercial buildings, pipes servicing fire suppression systems in unheated equipment rooms or loading docks are at high risk as well.

To mitigate the risk of your pipes freezing:

• Insulate pipes in unheated areas
• Seal air leaks allowing little to no intrusion of cold air
• Drain/winterize outdoor plumbing fixtures
• Keep your home adequately heated to protect your water supply line from the cold

Key Risk Factors for Frozen Pipes

There are several key risk factors that can lead to frozen pipes in your Blacktown home or business:

• Inadequate insulation - Exposed pipes or those near uninsulated exterior walls, attics, basements or crawl spaces is a signal to consider what to do with increased freezing risk.
• Sudden cold snaps - Quick drops in temperatures below freezing do pipes harm by catching them off guard before protective measures can be taken.
• Your thermostat set too low - Allowing indoor temperatures to drop below ideal settings puts nearby pipes at risk of cold water becoming ice.
• Leaks and water leaks - Gaps that allow frigid air from outside your dwelling to encircle pipes.

Ensuring proper insulation is key to safeguarding your pipes throughout prolonged cold periods. But additional precautions can help prevent problems when polar vortexes or other arctic fronts cause extreme or sudden temperature drops.

Preventative measures such as sealing leaks and cracks, allowing indoor taps to slightly drip in sub-freezing temperatures, and maintaining heating can mitigate the risk of freezing. Insulating vulnerable pipes, draining sprinklers/hoses, and shutting off main valves can make them less likely to freeze as cold weather approaches.

Preventing Frozen Pipes

There are several key steps you can take to help prevent pipes from freezing in your Blacktown home:

1. Insulate pipes effectively to guard against freezing in cold conditions. Use insulation wraps or heat tape on pipes in unheated areas like attics, basements, attic crawl spaces, and garages.
2. Seal air leaks and cracks allowing cold air inside near pipes. Use caulk and weatherstripping to close gaps along windows, doors, electrical outlets, etc.
3. Maintain your home’s temperature at a minimum of 13°C at all times, including when you’re away. Pipes located on exterior walls are especially vulnerable to freezing.
4. In cold weather, allow taps to drip overnight to keep water flowing and prevent pipes from freezing. Allowing a trickle of water through your plumbing system helps to avert freezing.
5. In extreme cold, consider opening kitchen bathroom cabinet doors to allow warm air to surround pipes under sinks.
6. Shut off water to and properly drain lawn sprinkler systems. Shut off and drain any isolated outdoor faucets.

Our licensed Sydney plumbers can assess your property in Blacktown, checking for at-risk pipes, insulation requirements, and other preparations to thwart pipe bursts. Contact us at 1300 349 338.

Detecting Frozen Pipes Before They Burst

Catching issues promptly is crucial to prevent frozen pipes burst and subsequent water damage. Be proactive during cold snaps by checking these areas for frozen pipes:

• Pipes along exterior walls, where ice can form or lacking insulation
• Isolated pipes in unheated rooms like attics, basements and crawl spaces
• Outdoor hose bibs and pool equipment

Early signs of frozen pipes include:

• Reduced water flow from fixtures
• Noisy pipes or sounds of expanding ice
• Sections of pipe feeling much colder than surrounding areas

If you suspect a frozen pipe, call our 24/7 emergency plumbing line immediately at 1300 349 338. We can evaluate for damage and showcase thawing methods using heat and compressed air. Understanding how to thaw frozen pipes promptly can greatly reduce the likelihood of bursting and water damage.

Thawing Frozen Pipes Safely

If you discover a frozen pipe, it is crucial to thaw it safely to avoid burst pipes, flooding, and water damage.

1. Shut off the main water supply valve. It’s important to know where your main water shutoff valve is located and turn the water off to the entire home to alleviate pressure in the pipes.
2. Open a faucet downstream from the frozen section. Opening a faucet ensures the liquid water that comes out from the melting ice can flow through, easing water through pipe sections.
3. Apply heat with a hair dryer, heat lamp or space heater directly around pipe sections suspected of freezing. Continue until normal water pressure resumes. Never use any open flame.
4. Consider pipe insulation after thawing. Uninsulated pipes that have frozen once are likely to freeze again.
5. Should a pipe burst, immediately turn off the water and contact a plumber. Significant flooding can happen quickly.
