By When temperatures plummet and suddenly start to rise, frozen or burst pipes can ruin just about anything as a homeowner in Ontario’s worst nightmare – especially when it’s your water heater. Left untreated, the problem can lead to severe water damage, expensive repairs, and days without hot water.
We can appreciate how immediate and unpredictable these circumstances can be at Aire One Peel Brampton. This guide will lead you through the vital emergency steps to follow if your water heater pipes freeze or burst, as well as how to keep your plumbing system from freezing when the weather turns icy.
Why Water Heater Pipes Freeze in Winter
Even a working water heater can have pipes that bring cold water into the unit—or hot water throughout the house—that are prone to freezing when it’s cold outside.
Common causes include:
- Poorly insulated pipes
- Sudden temperature drops
- When long periods of no or low water use occur
- Basements or utility rooms with cold gusts.
When water inside the plumbing freezes, pressure builds — and that can lead to burst pipes, leaks or even a failed whole-house water heater.
Emergency Steps If Your Water Heater Pipes Freeze
1. Turn Off the Water as Soon as Possible
- At the first sign of freezing, shut off the building’s main water valve.
- This reduces the risk of overflow if the piping thaws and cracks.
2. Shut Off the Electricity to the Water Heater
- Electric: turn off the circuit breaker for the water heater
- Gas: Turn the gas valve to “OFF.”
Wrestling with a hot-water heater with no water flow can burn out the heating elements or damage the tank.
3. Locate the Frozen Section
Familiar places to check:
- Basement walls
- Crawl spaces
- Attics
- Areas near exterior walls
- Pipes near open windows or vents
If the pipe is frosted or bulging, that could be a sign of additional freezing further down—stop and call in a professional.
4. Warm the Pipe Gradually
Never use an open flame. Instead, try:
- A space heater
- A hair dryer
- Warm towels
- Heating pads
Gradually and evenly warm until water flows out. Too much heat too soon, and the pipe can crack.
How to Prevent Frozen or Burst Water Heater Pipes
Insulate Exposed Pipes
The simplest system uses foam sleeves that slip onto water pipes, but these won’t work if the temperature drops well below freezing.
Keep the Utility Room Warm
A tiny space heater or slight improvement in airflow can be the difference between a full screen of data and black bars.
Let Faucets Drip in Extreme Cold
A slow dribble can prevent water from stagnating and freezing.
Seal Drafts
Inspect around windows, doors, and wall-fastened pipes.
Schedule a Winter Tune-Up
A pro will check whether your water heater is ready for action this season!
