How to Prevent Frozen Pipes: Toronto Winter Plumbing Guide

Toronto's freezing winters can cause pipes to freeze and burst, leading to costly damage. Here’s how you can protect your home:

1. Insulate Pipes: Use foam sleeves, fiberglass wrap, or heat cables for pipes in unheated areas like basements, attics, and garages.
2. Keep Your Home Warm: Maintain indoor temperatures at 17°C or higher, even when away. Use a programmable thermostat for consistency.
3. Winterize Outdoor Plumbing: Shut off outdoor water lines, drain hoses, and install foam faucet covers or frost-proof taps.
4. Handle Extreme Cold: Let faucets drip during cold spells, open cabinet doors to circulate warm air, and seal drafts around pipes.

Quick Tips:

• Inspect pipes annually for gaps or damage.
• Use space heaters in cold spots like basements or garages.
• Call a plumber if you notice water pressure drops or leaks.

Taking these steps early can save you thousands in repairs and keep your plumbing safe all winter.

How to Prevent Frozen and Burst Pipes

Step 1: Add Pipe Insulation

Protecting your pipes from Toronto's freezing temperatures starts with proper insulation. The city's harsh winters can wreak havoc on plumbing systems, so insulating at-risk pipes is a must.

Identify Pipes at Risk of Freezing

Focus on areas in your home where pipes are most likely to freeze:

• Unheated spaces: Basements, attics, crawl spaces, and garages
• Exterior walls: Pipes near outside-facing walls
• Known trouble spots: Areas where pipes have frozen in the past

During winter, feel for cold spots on pipes - these are the ones that need insulation.

Choose the Right Insulation

Pick an insulation type that suits your specific pipes and conditions:

Steps to Insulate Pipes

1. Clean the pipes: Remove dirt and moisture, and let them dry completely.
2. Measure and cut: Trim foam sleeves to match pipe lengths.
3. Wrap the pipes: Open the pre-slit seam and fit the insulation snugly around the pipe.
4. Secure the seams: Use insulation tape or duct tape to hold everything in place.
5. Cover corners and joints: Cut insulation at angles to ensure complete coverage.

After installation, check for gaps, loose spots, or exposed areas, especially at joints. True Service Plumbing advises inspecting your insulation every year before winter to ensure it’s still effective.

If you're unsure about installation, hiring a plumber can save you from potential mistakes and costly repairs.

While insulation is a key step, keeping your indoor temperatures steady also helps prevent pipes from freezing.

Step 2: Keep Your Home Warm

Best Temperature Settings

Maintaining steady indoor temperatures is key to protecting your pipes during Toronto's cold winters. Pair this with proper pipe insulation to safeguard against freezing. Always set your thermostat to at least 17°C (63°F), even when you're not home.

Here’s a quick guide to recommended temperature settings:

Using a programmable thermostat can help maintain these temperatures consistently, avoiding risky drops.

Help Heat Reach Your Pipes

Setting the thermostat is only half the battle. Ensuring warm air gets to your pipes is just as important. Here are some practical tips to improve heat distribution:

• Open Cabinet Doors: Leave the cabinets under sinks open so warm air can circulate around pipes and plumbing.
• Address Cold Spots:
  • Basements: Use a space heater in unfinished areas with exposed pipes.
  • Exterior Walls: Move furniture slightly away from walls to allow better air circulation.
  • Garages: If your garage has plumbing, consider adding a small heater.
• Seal Drafts: Block out cold air with weatherstripping around doors and windows or place draft stoppers under doors leading to unheated spaces.

For extra peace of mind, install temperature sensors in areas where pipes are most at risk. These can alert you to dangerous drops before problems arise.

While indoor plumbing needs attention, don’t forget to take steps to protect outdoor pipes from freezing as well.

Step 3: Winterize Outdoor Plumbing

Outdoor plumbing in Toronto's freezing winters needs extra attention to prevent damage. Taking the right steps before temperatures drop can save you from costly repairs.

Empty Outdoor Water Lines

Start by shutting off the interior valves connected to outdoor faucets (these are usually located inside, near the fixture). Next, disconnect and drain garden hoses, then open the outdoor faucets to let any remaining water flow out. Make sure to do this before the first frost hits.

You might also want to think about upgrading to frost-proof faucets. These have a long stem that positions the shut-off valve inside your home, keeping it away from freezing temperatures. This simple change can help prevent winter damage.

Insulate and Seal Outdoor Plumbing

To shield outdoor plumbing from the cold, use these tools:

• Foam faucet covers to protect outdoor taps.
• Pipe insulation sleeves for any exposed pipes.
• Heat cables that adjust to temperature changes, ideal for spots that face extreme cold.

Check for gaps around pipes where they enter your home, especially at the foundation or exterior walls. Seal these gaps with caulking or expanding foam.

Once you've taken these steps, your outdoor plumbing will be ready to handle Toronto's toughest winter weather.

Step 4: Handle Extreme Cold Weather

When temperatures plunge, standard insulation and maintaining steady indoor warmth might not be enough to safeguard your plumbing. Extra steps are necessary to prevent costly damage.

Extra Steps for Cold Weather Protection

When extreme cold hits, take these steps in addition to basic precautions like opening cabinet doors and letting faucets drip:

• Keep your thermostat above 13°C to avoid sudden temperature drops in areas with exposed pipes.
• Focus on unheated spaces, as pipes in these areas are more likely to freeze quickly.
• Watch for freezing signs, such as lower water pressure, and act immediately to avoid full blockages.

Safe Ways to Thaw Frozen Pipes

If you suspect a pipe has frozen, use one of these safe methods to thaw it:

Avoid open flames or high heat tools, as they can cause pipes to burst or lead to fires. Keep faucets open while thawing so water and steam can escape.

When to Call a Plumber

Certain situations require professional help. Contact a plumber if you notice:

• Water damage on walls or ceilings
• Strange noises like banging, whistling, or gurgling in pipes
• A sharp drop in water pressure
• No water coming from multiple fixtures
