Winter in Canada is a time of beauty, but it’s also a season when frozen pipes become a serious concern for homeowners. When temperatures plummet, frozen water in pipes can lead to burst pipes, causing expensive damage and frustration.
In this guide, we’ll share expert advice on how to prevent frozen pipes, address common questions like “What temperature will pipes freeze?” and provide actionable steps to keep your plumbing safe throughout the cold weather.
At What Temperature Do Pipes Freeze?
Pipes begin to freeze when the temperature reaches 0°C (32°F). However, in poorly insulated areas or where pipes are exposed to cold drafts, freezing can occur at slightly higher temperatures. Burst pipes are especially likely when temperatures drop below -6°C (21°F).
Why Do Frozen Pipes Burst?
When water inside a pipe freezes, it expands, causing immense pressure on the pipe walls. If the pressure becomes too great, the pipes burst or crack, leading to water damage once the ice thaws.
Signs of a Frozen Pipe
Spotting a frozen pipe early can save you from costly repairs. Look for these warning signs:
- No water flow: A common sign of frozen pipes is restricted or no water flow from faucets.
- Frosty pipes: Visible frost on exposed pipes is a clear indicator of freezing.
- Unusual smells: Strange odours coming from faucets or drains may signal a partially frozen pipe.
How to Avoid Frozen Pipes
- Insulate Pipes: Pipes in unheated spaces like basements, garages, and attics are most at risk. Wrap these pipes with foam or fibreglass insulation to keep them warm.
- Seal Gaps and Drafts: Inspect your home for any gaps around windows, doors, or where pipes enter walls. Seal these gaps with caulk or weatherstripping to prevent cold air from reaching your pipes.
- Maintain a Consistent Temperature: Keep your home warm, even when you’re away. Set the thermostat to at least 15°C (59°F) to prevent frozen pipes. Avoid lowering the temperature too much at night.
- Allow Faucets to Drip: On extremely cold nights, let your outdoor faucets drip slightly. The running water reduces the chances of a completely frozen pipe.
- Open Cabinet Doors: In areas like kitchens and bathrooms, opening cabinet doors lets warm air circulate pipes, especially if they’re near exterior walls.
- Disconnect Outdoor Hoses: Remove and drain garden hoses before winter. A frozen hose can back up water into the pipe, leading to potential damage.
What to Do If Your Pipe Freezes
If you suspect a pipe is frozen, follow these steps:
- Shut off the water: If the pipe bursts, turn off the main water supply to prevent further damage.
- Thaw the pipe gradually: Use a heating pad or warm towels to thaw the frozen pipe. Never use an open flame.
- Call a professional: If you can’t locate the frozen pipe or safely thaw it, contact a licensed plumber immediately.
Long-Term Solutions to Avoid Frozen Pipes
- Install Pipe Heating Cables: Heat cables or heat tape are excellent for pipes in extremely cold areas. These cables keep the pipes warm during harsh winter conditions.
- Add Home Insulation: Proper insulation in your walls, attic, and basement can help keep your entire home warmer and protect pipes from freezing.
- Upgrade to Weather-Resistant Pipes: If you’re renovating or building a home, consider using freeze-resistant pipes designed to withstand extreme temperatures.
The Cost of Ignoring Frozen Pipes
Ignoring frozen pipes can lead to burst pipes and costly repairs, often running into thousands of dollars. Taking preventive steps, such as insulating pipes and maintaining your home’s temperature, is far less expensive and more effective. By taking these steps, you can keep your home safe from frozen water pipes.
