What we cover
Sewage in the basement floor drain
Most common sign — black or brown water bubbling up from the lowest drain in the house.
Multiple toilets backing up
Especially with foul odour. Almost always a main-line blockage downstream of all fixtures.
Gurgling drains across the house
Air being pushed up through traps as water tries to back up — a sewer backup is starting or imminent.
Sewage smell with no visible water
Could be a dry trap or a venting problem; could be a slow main-line leak. Worth diagnosing before it gets worse.
What to do before the plumber arrives
- 1
Stop using all water in the house.
No flushing, no laundry, no dishwasher, no showers. Every litre you put down a drain ends up on your basement floor.
- 2
Keep people and pets out of the affected area.
Raw sewage is a biohazard. Don't let kids near the standing water; don't stand in it yourself without rubber boots.
- 3
Open windows for ventilation.
Sewer gas is unpleasant and, in concentration, dangerous.
- 4
Move what you can salvage.
Anything porous in the affected area is going to be a write-off — get the rest to higher ground.
- 5
Photograph everything for insurance.
Most Alberta homeowner policies require sewer-backup endorsement riders — document the damage now to support your claim.

Frequently asked questions
- Why does this require a licensed plumber specifically?
- Sewer-line work in Edmonton requires a plumbing permit (Bylaw 18965) and that means a holder of a valid Alberta plumber's license. OnCall Pros only dispatches sewer calls to verified license-holders — that's enforced in the trade module.
- Will I need to dig up the line?
- Not always. Most backups clear with an auger from the basement clean-out. If the line is collapsed or root-infested past saving, the plumber will scope it with a camera and quote a dig or trenchless repair.
- Does the City of Edmonton cover any of this?
- Only if the blockage is on the city's portion of the line (past your property line). The plumber's camera scope tells you which side it's on, which is the document you'll need for an EPCOR / city service request.
- What about cleanup?
- The plumber clears the cause; they don't typically do the biohazard cleanup. Once the line is flowing, call a restoration company (your insurance can usually recommend one) for the actual mitigation work.
Edmonton-specific notes
Edmonton's older neighbourhoods (especially north of the river — Westmount, Inglewood, Norwood) have clay-tile sewer laterals that are vulnerable to root intrusion and shifting. If you've had two sewer backups in five years, your lateral likely needs replacement. Backups also climb sharply during spring melt (late March to mid-April) when frozen ground keeps surface water from draining and the city sanitary main runs near capacity — that's when a marginal lateral that handled the dry months gives up. Backwater valves are now mandatory on new builds in Edmonton; if your home pre-dates 2007 and doesn't have one, ask the responding plumber to quote retrofit during the cleanup visit.
