Canadian winters are brutal – and your plumbing system often takes the hardest hit. As temperatures drop, your home becomes more vulnerable to a range of plumbing emergencies that can lead to costly damage if not addressed quickly. In this post, we’ll cover the top 5 winter plumbing emergencies in Canada and provide practical tips to help you prevent them before they turn into disasters.
1. Frozen Pipes
Why it happens: When temperatures plunge below freezing, exposed or poorly insulated pipes can freeze, blocking water flow and potentially bursting due to pressure buildup. Consequences: Burst pipes can cause extensive water damage, mold growth, and thousands of dollars in repair costs. How to prevent it:- Insulate pipes in unheated areas like basements, attics, and crawl spaces.
- Keep the thermostat set to a consistent temperature (at least 15°C).
- Let faucets drip slightly during extreme cold to keep water moving.
2. Burst Water Heater
Why it happens: Cold weather forces your water heater to work overtime, increasing pressure and strain on the tank. Consequences: A burst heater can flood your home, destroy flooring, and leave you without hot water in sub-zero temperatures. How to prevent it:- Flush your water heater yearly to remove sediment buildup.
- Schedule a professional inspection before winter hits.
- Consider upgrading to a modern, energy-efficient model if yours is over 10 years old.
3. Clogged Drains and Sewer Backups
Why it happens: Cold weather solidifies grease and debris, making drains more prone to blockages. Snowmelt and ground freezing can also affect sewer lines. Consequences: Clogged drains can lead to water backups in sinks, tubs, and toilets – and even dangerous sewer overflows. How to prevent it:- Avoid pouring fats, oils, or grease down the drain.
- Install drain screens to catch hair and debris.
- Have your sewer line inspected and cleaned annually.
4. Sump Pump Failure
Why it happens: A frozen discharge line or power failure can stop your sump pump from doing its job – pumping out excess water from your basement. Consequences: Water accumulation can lead to basement flooding, structural damage, and mold infestations. How to prevent it:- Install a backup battery for your sump pump.
- Insulate or heat the discharge pipe to prevent freezing.
- Test the pump monthly during the winter season.
5. Outdoor Hose Bib Damage
Why it happens: Leaving hoses connected to exterior faucets can trap water in the pipe, which freezes and expands, causing cracks. Consequences: This can burst pipes inside the wall, causing slow leaks that are hard to detect until major damage occurs. How to prevent it:- Disconnect all garden hoses before winter.
- Shut off the indoor valve connected to the outdoor tap and drain the pipe.
- Install frost-proof hose bibs if possible.
