Take the first action that fits the water source

For sewage backing up through fixtures, stop using water: taps, toilets, laundry and dishwashers add wastewater to a system that may not be draining. For a leaking pressurized supply pipe, shut the known household water valve only if it is safely accessible. These actions solve different immediate problems; closing the supply valve will not stop a public sewer from surcharging.

For water entering around a sump pit or across a wall, report the entry point and pump behaviour without reaching into the pit. Keep children and pets away from contaminated water. Do not enter a flooded area near electrical equipment; ask the electric utility to make it safe. See sewer backup response for wastewater-specific steps.

Which emergency service may be needed?

An urgent blockage may call for emergency clearing, while a confirmed break preventing flow requires repair planning. A pump that runs without lowering the pit needs assessment of discharge and capacity as well as the motor. Report what the equipment is doing, not just that the basement is wet.

For a burst or frozen pipe, explain whether it carries incoming water or drainage. Heating, gas, electrical work and flood-restoration services require their own appropriately qualified help; a drain service request does not establish that all those trades are included. Confirm the service type before an appointment is arranged.

When the municipality should be contacted

A public main problem can affect a home even when its private lateral is intact. Follow your municipality’s reporting procedure, particularly if several properties are affected or public-side damage is suspected. Local contractor and cost-recovery arrangements differ; use the municipality directory to find the relevant guidance.

Keep the time of your report, the reference number and any instructions. Do not assume private emergency work will be reimbursed by the municipality. Municipal response and a privately requested appointment are separate arrangements. Tell each party about any work already authorized so the response is coordinated.

Safety checks still apply to urgent clearing

Before motorized or water-jet clearing of a blocked outside sewer, arrange the sewer safety inspection described by Enbridge. A gas line crossing through the sewer can be struck by clearing equipment. Do not try to force an auger through an unknown obstruction while waiting for help.

Leave backed-up cleanouts closed and avoid adding chemical cleaners. Tell the technician about any product already poured into the drain and provide its label if safely available. An active leak, unstable ground or sewage contamination may limit where the technician can work until the hazard is controlled.

What to confirm before dispatch

Ask whether a crew is available for your address, what the call-out or assessment charge covers, whether after-hours rates apply and which work requires separate approval. Give the unit number, safe access instructions and a callback number. A quoted arrival estimate should be confirmed in the conversation rather than inferred from this page.

Describe whether the problem affects one fixture or several, when it began and whether previous clearing lasted. Share any inspection report. That information helps avoid booking the wrong equipment or assuming structural failure before it has been established. No fixed response time, universal 24-hour availability or standard price is represented here.

Separate immediate relief from the permanent fix

Restoring flow or isolating a leak can reduce immediate damage while the underlying defect still needs investigation. Ask what was established, what remains unknown and which fixtures can be used safely afterward. If the line could not be inspected, record that limitation rather than treating temporary relief as a clean bill of health.

Photograph damage only from a safe position, retain invoices and ask your insurer about documentation and cleanup arrangements. A restoration contractor may be needed for contaminated materials. Once the emergency is stable, compare any proposed major repair with the evidence and a written scope.
