7 Winter Plumbing Problems in Toronto Homes & How to Prevent Frozen Pipes

Toronto winters bring icy temperatures, snow, and a unique set of plumbing challenges that can leave homeowners facing expensive repairs if they’re not prepared. Frozen pipes, leaks, and drainage issues are just some of the problems we see every winter at SUPER PLUMBER. Fortunately, with local expertise and proactive care, you can prevent the most common winter plumbing problems and keep your Toronto home running smoothly all season long.

1. Frozen Pipes

One of the most notorious winter plumbing problems, frozen pipes are a frequent emergency in Toronto’s coldest months. Water inside pipes can freeze and expand, leading to bursts and major water damage.

Prevention Tips:

- Insulate exposed pipes in basements, crawl spaces, and exterior walls.

- Let faucets drip slightly during extreme cold to keep water moving.

- Keep interior temperatures consistent and warm, especially in unused areas.

2. Pipe Bursts

If a frozen pipe is left untreated, it can burst, sending gallons of water into your home within minutes. Quick action is critical, but the best solution is prevention.

Prevention Tips:

- Schedule a pre-winter plumbing inspection to identify at-risk pipes.

- Seal cracks and gaps in your home’s exterior to reduce cold airflow.

- Know the location of your main water shut-off valve.

3. Clogged Drains

Holiday cooking and increased indoor activities often lead to more food waste, grease, and hair in the drains—raising the chances of clogs just when you least need them.

Prevention Tips:

- Avoid pouring grease and oils down the kitchen sink.

- Use drain screens to catch hair and debris in bathrooms.

- Schedule professional drain cleaning before winter for a fresh start.

4. Water Heater Failure

Cold weather means increased demand on your water heater. Older or neglected units may struggle or fail entirely, leaving your family with cold showers.

Prevention Tips:

- Flush your water heater annually to remove sediment build-up.

- Insulate your water heater and the surrounding pipes.

- Consider upgrading to an energy-efficient, modern system.

5. Sump Pump Malfunctions

Melting snow and winter rains can flood basements if your sump pump isn’t working properly.

Prevention Tips:

- Test your sump pump at the start of each season.

- Keep discharge pipes clear of snow and debris.

- Have a backup power source to keep the pump running in outages.

6. Leaky Fixtures

Extreme temperatures can cause older seals and connections to fail, resulting in leaks around sinks, toilets, or tubs.

Prevention Tips:

- Check all fixtures for drips and pooling water.

- Replace worn-out washers and seals before winter.

- Schedule routine inspections with a trusted Toronto plumber.

7. Backed-Up Sewer Lines

Thawing and freezing cycles can cause cracked pipes or tree root intrusion, leading to messy and hazardous sewer backups.

Prevention Tips:

- Never flush wipes or hygiene products down the toilet.

- Ensure sump pump and backwater valves are in good working order.

- Arrange a camera inspection if you notice slow drains or gurgling sounds.
