What to do right now
Open every tap and flush every toilet
Turn on all your taps and flush each toilet. EPCOR says that if water isn't flowing and there is no known water main break in your area, you likely have a frozen service line.
Frozen service line? Call EPCOR
EPCOR treats a frozen service line as a water emergency. Call 780-412-4500 at any hour.
EPCOR's published fee for thawing a frozen water service is nothing for the first visit and $300 an hour for a second visit.
Don't leave it frozen
EPCOR says it's important to act quickly and thaw your pipes. Freezing spreads further along the line over time, which makes it harder and slower to thaw. The longer a pipe stays frozen, the more likely it is to burst.
Thaw with gentle heat only
Never use a torch, lighter or any open flame to thaw a pipe. Keep hair dryers and heaters away from water.
EPCOR suggests gentle heat from a hair dryer, space heater or heat lamp on a narrow pipe, kept away from water and anything that can burn. Don't try this in a tight space without room to move and fresh air.
Watch for a burst
As the pipe thaws, watch for water where it shouldn't be. If a pipe bursts, follow the burst pipe steps.
Won't thaw? Get a pro
EPCOR's advice: if you're not sure what to do, or the pipe won't thaw, contact a plumbing or heating company.
Heat off in the house?
If your furnace or heat pump breaks, the Insurance Bureau of Canada advises shutting off the water supply and draining the pipes. In a power outage, Alberta suggests turning off the main water supply and letting the taps drip slightly.

Frozen pipes signs in an Edmonton winter
The sign EPCOR names is no water, or just a trickle, from your taps.
Environment and Climate Change Canada's 1991 to 2020 normals for Edmonton put the January daily average at -10.3 °C and the January daily low at -14.7 °C. They also count about 24 nights a year below -20 °C.
Frozen pipes, exterior wall or crawl space
EPCOR points to the cold spots: basements and crawl spaces, especially where the water line enters the home. Outdoor hose taps can freeze and burst too, and EPCOR says that can cause water damage inside your home.
How to prevent frozen pipes from bursting
- Keep your home heated at normal levels so there are no cold spots.
- Let a tap drip. EPCOR says even a slow drip of hot or cold water can help prevent freezing.
- Disconnect outdoor hoses and turn off the outdoor taps.
- Keep EPCOR's curb stop valve clear. EPCOR needs to reach it in an emergency such as a frozen service line, and the property owner must keep it accessible.
Away for the winter? The Insurance Bureau of Canada says most policies exclude frozen pipe damage while a home is vacant.

Questions
Can frozen pipes thaw on their own?
Don't count on it. EPCOR says freezing spreads further along the line over time, making it harder to thaw.
Can frozen pipes burst?
Yes. EPCOR warns that a pipe is more likely to burst the longer it stays frozen. Outdoor hose taps can burst too.
Frozen pipes: should I turn off the water?
If a pipe has burst, yes, at the main valve, if you can reach it dry. If your furnace breaks, the Insurance Bureau of Canada advises shutting off the water and draining the pipes. In a power outage, the Government of Alberta advises turning off the main water supply and letting the taps drip slightly.
Frozen pipes: leave the water running?
As prevention, yes. The Government of Canada suggests running a trickle of water when pipes can't be kept above freezing. EPCOR says even a slow drip helps.
Are frozen pipes an emergency?
A frozen water service line is. EPCOR names it as a water emergency and takes calls about it at 780-412-4500. A frozen pipe inside the house needs action too, because the longer it stays frozen, the more likely it is to burst.
