How to Prevent Water Pipes from Bursting: 5 Top Tips from the Pros

Burst pipes can cause major water damage and expensive repairs, especially during cold weather. While we're not necessarily in the midst of cold weather right now, it certainly pays to know how to prevent water pipes from bursting when the temperatures inevitably drop.

When temperatures fall, pipes located in unheated areas such as crawl spaces or exterior walls are typically at the highest risk of freezing. Once water freezes it expands and increases pressure in the pipes and often causes cracks or pipe bursts.

Thankfully, there are numerous ways to protect your pipes from bursting when temperatures plummet. Here are 5 relatively simple tips to take on board for the upcoming winter.

1. Insulate Exposed Pipes to Keep Them Warm

Insulating pipes is one of the best ways to stop them from freezing during cold weather.

Exposed pipes in crawl spaces, exterior walls or unheated areas are most susceptible to freezing when temperatures drop. However, if you add insulation to your pipes – foam or rubber sleeves will often do the trick – it will keep your pipes warm and prevent freezing. You can also wrap pipes with heat tape for extra protection in extreme cold.

Focus on exposed pipes near the following areas:

• kitchen and bathroom sinks
• main water supply lines
• hot water systems

Pipe insulation prevents frozen pipes, keeps water flowing, and helps you avoid costly repairs.

2. Keep Water Flowing During Cold Weather

Keeping water flowing through your pipes during cold weather can significantly reduce the risk of freezing.

Allow a small trickle of water to flow from your taps when temperatures drop, especially those connected to pipes in exterior walls or unheated areas. This movement stops water from freezing and keeps water pressure consistent in your supply lines which lowers the risk of burst pipes.

Concentrate on high-risk areas like kitchen and bathroom sinks where pipes are more exposed to cold air. Running water may seem like a small step but it can make a big difference in preventing damage.

3. Seal Cracks and Gaps Around Pipes

The third of our “how to prevent water pipes from bursting” tips is to seal cracks and gaps around your pipes.

Check areas where pipes pass through walls, floors or ceilings, especially near exterior walls and sill plates. Use weatherproof sealants or expandable foam to block drafts and keep pipes warm. Focus on areas around bathroom sinks, water supply lines and kitchen pipes as these are more exposed to cold air.

Sealing these gaps doesn’t just reduce the risk of frozen pipes. It also improves your home’s energy efficiency and protects against avoidable property damage from burst pipes.

4. Use Heat to Thaw Frozen Pipes Safely

If your pipes freeze despite putting precautions in place, careful use of heat sources can thaw them out and restore water flow. Focus on the frozen section and apply heat gradually to avoid damaging the pipes. Safe methods include:

• Warming the area with a space heater, keeping it away from flammable materials.
• Using a hairdryer, starting at the frozen area and working toward the water supply.
• Wrapping the frozen pipe with towels soaked in warm (not hot) water.
• Keeping cabinet doors open to allow warm air to reach pipes under kitchen and bathroom sinks.

Never use open flames as they can cause serious damage or pose a fire risk. Always monitor the process closely.

5. Drain and Shut Off Outdoor Water Supplies

The final of our “how to prevent water pipes from bursting” tips is to drain and shut off outdoor water supplies. This is key to preventing pipes from freezing and bursting during cold weather.

Begin by disconnecting garden hoses and draining water from outdoor taps. Shut off the water supply to outdoor pipes at the main valve and make sure to drain the lines of any remaining water. Focus on sprinkler systems and drain them completely to avoid frozen water damaging the pipes.

These simple steps will protect your outdoor water supply lines and reduce the risk of costly repairs from burst pipes.

Why You Should Always Call a Licensed Plumber For Burst Pipes

When it comes to your water pipes, a licensed plumber has the expertise and tools to fix and prevent issues safely and efficiently. No matter what your issue is, a professional can thoroughly assess the situation to determine the best way to resolve it. That solution may be something as easy as adding insulation, or as essential as providing pipe relining services that effectively create a new layer within your existing pipe.

Licensed plumbers ensure your water supply lines meet safety standards and can find hidden problems that may blow out into highly expensive repairs if you don’t get on top of them ASAP. DIY fixes often make relatively small problems significantly worse. They are also illegal, so always call a licensed plumber to protect your home from water damage and property loss.

Signs That Your Pipes Have Burst

We now know how to prevent water pipes from bursting. But it’s worth acknowledging that you can diligently put all these tips into place and still find yourself dealing with a burst pipe at some point. Things just happen sometimes. If you do find yourself in this unfortunate position, identifying the common signs of a burst pipe can help you get on top of the problem quick smart. If you suspect an issue, keep an eye out for:

• A sudden drop in water pressure or no water flow at all.
• Unusual puddles of water that appear indoors or around your property.
• Higher than normal water bills, which could indicate hidden leaks.
• Strange noises, like banging or gurgling, coming from your pipes.
• Your water meter runs constantly, even when no one is using water.
• Damp spots, mould, or discoloured patches on walls, ceilings, or floors.

Recognising these signs early can help you prevent extensive damage and quickly restore your water supply. Always call a licensed plumber to assess and repair burst pipes safely.

Keep Your Pipes and Home Safe

Knowing how to prevent water pipes from bursting may not be difficult, but it will require some planning on your part.

By insulating exposed pipes, sealing gaps, keeping water flowing and managing outdoor water supplies you can reduce the risk of costly damage when temperatures drop. Acting early can prevent frozen pipes, water leaks and the stress of dealing with burst pipes. If you suspect a problem or need guidance always call a licensed plumber for safe and reliable solutions.

Taking these proactive steps will protect your home, water supply and wallet from the challenges of winter.
