How to Prevent Frozen Pipes in Manitoba Winters

When the temperature plummets across Steinbach and Winnipeg, your home’s plumbing system goes onto the front lines. A frozen pipe isn’t just an inconvenience; it’s a ticking time bomb. When water freezes, it expands with immense force, easily cracking copper, PVC, and PEX piping. Once that ice thaws, a single burst pipe can release hundreds of gallons of water into your home in a matter of hours.

When ice forms, it pushes water toward the closed faucet, causing immense pressure buildup that leads to a burst.

The Early Warning Signs of Freezing Pipes

Catching a frozen pipe before it bursts can save you thousands of dollars in water damage. Pay attention to these three critical warning signs when the deep freeze sets in:

  • A drop in water pressure: If you turn on your kitchen or bathroom faucet and only a trickle or a few drops come out, ice has likely formed inside the line.
  • Visible frost: For exposed pipes in your basement, crawlspace, or beneath sinks against exterior walls, physically look for a layer of white frost or condensation on the outside of the pipe.
  • Strange odors: If a pipe is blocked by ice, the normal venting process of your plumbing can be obstructed, occasionally pushing strange smells back up through your drains.

4 Steps to Protect Your Plumbing

Prevention is significantly cheaper than a middle-of-the-night emergency plumbing call. Here is how you can winterize your home right now:

1. Insulate Vulnerable Pipes

Pipes located in unheated areas—such as garages, attics, crawlspaces, and exterior walls—are highly susceptible to freezing. Wrap these lines in foam pipe insulation or fiberglass sleeves.

Ensure all exposed pipes in unheated areas are tightly wrapped with foam insulation, securing the seams completely.

2. Let the Faucet Drip

If the forecast predicts extreme negative temperatures, turn on your faucets just enough to allow a slow, steady drip. Moving water is much harder to freeze, and leaving the tap open slightly relieves the pressure inside the system if ice does begin to form.

3. Open Cabinet Doors

Plumbing housed under kitchen and bathroom sinks is often completely cut off from your home’s heating system. Open those cabinet doors to let the warm air from your house circulate around the pipes.

4. Seal Drafts and Cracks

Take a walk around your home’s exterior and basement. Look for any cracks or gaps near where pipes run and seal them with caulk or expanding foam. Even a tiny draft of -30°C air hitting a pipe directly can freeze it in hours.

⚠️ Never Do This to a Frozen Pipe

If you discover a frozen pipe, never use an open flame, blowtorch, or propane heater to thaw it. Not only is this a massive fire hazard, but boiling the water inside the pipe too quickly can cause the pipe to explode from steam pressure. Instead, use a hair dryer on a low setting, a space heater kept safely away from flammable materials, or wrap the pipe in towels soaked in warm water.

What to Do When a Pipe Freezes (Or Bursts)

If you turn on your faucet and nothing comes out, do not wait for the situation to resolve itself. Leave the faucet turned on so that as the ice melts, the water has somewhere to flow.

The Golden Rule of Plumbing Emergencies: Know exactly where your main water shut-off valve is located. If a pipe does burst, turning this valve off immediately is the only way to stop the flooding.
