Stop using water now. Do not flush toilets, run taps, shower, start laundry or run the dishwasher. If sewage is coming up through a basement floor drain, tub or shower, keep people and pets away from it and stay clear of wet electrical areas. If you are in Kingston and the backup is active, call an emergency sewer and drain specialist at (613) 328-6600. TAP TECH answers 24/7 for backups and flooding, and you get the exact flat-rate price before any work starts.
A sewer backup usually means wastewater has nowhere to go. In many cases, the problem is in the main line, the main pipe that carries wastewater from the house to the municipal sewer. Until proven otherwise, treat it as a whole-house drain issue, not a single clogged fixture. For a basement-specific first response, TAP TECH also explains why you should stop using water immediately when sewage is in the basement.
What to do in the first 10 minutes during a sewer backup
Should you use water during a sewer backup?
No. During a sewer backup, any water you send into the system can come back through the lowest open drain. For a Kingston home, an emergency sewer and drain response is safest when everyone in the building stops adding flow right away. Wait until the line has been cleared and checked before normal water use starts again.
Use these steps first:
- Stop all water use: Do not flush, shower, wash dishes, run laundry or use any appliance that drains water.
- Tell everyone in the home or building: One accidental flush can push more sewage onto the floor.
- Keep people and pets away: Sewage can contain bacteria, viruses and other contaminants.
- Avoid wet electrical areas: If water is near outlets, panels or cords, stay back and wait for qualified help.
- Do not pour in drain cleaner: Chemical drain cleaners can sit in the backed-up line and create a hazard for anyone opening the drain.
- Call for emergency drain service: If more than one fixture is affected, or sewage is visible, treat it as urgent.
If every drain in the house is slow but sewage has not surfaced yet, the same rule applies. Stop using water and read TAP TECH’s guide on what to do when every drain is slow before help arrives.
Why emergency sewer and drain crews tell you to stop all water use
When a main line is blocked, water cannot leave the property normally. Every flush, shower or sink full of water adds pressure behind the blockage. That pressure often finds the lowest exit point, which is why a Kingston basement floor drain, tub or shower may be the first place sewage appears.
A true emergency sewer and drain problem is not solved by “testing” the drain with more water. Testing can spread contamination, increase odour and make cleanup harder. If you searched for Emergency Drain Cleaning Kingston because wastewater is already backing up, the safest test is no test at all. Stop flow and get the line assessed.
| Water use during a backup | What can happen | What to do instead |
|---|---|---|
| Flushing a toilet | Sewage may rise from a floor drain, tub or shower | Leave toilets unused until the line is cleared |
| Running a shower | Several litres can enter the blocked line quickly | Wait for confirmation that the main line is open |
| Starting laundry | A washer can discharge a large volume fast | Turn the machine off and leave it off |
| Running a dishwasher | Warm, dirty water may add to the backup | Pause the cycle if safe to do so |
| Opening taps “just to check” | More water may come back into the home | Let a drain specialist inspect the line |
What can you safely check before help arrives?
You do not need to diagnose the whole sewer line yourself. The goal is to gather useful information without making the backup worse. A cleanout is an access point into the drain or sewer line, often found in a basement, utility room or outside near the foundation.
- Look from a dry area: Note whether the backup is coming from a floor drain, shower, tub or another low fixture.
- Check how many fixtures are affected: Multiple slow or backing-up drains point toward the main line.
- Do not open a cleanout under pressure: If wastewater is already pushing up, opening a cap can release more sewage.
- Think about recent warning signs: Gurgling toilets, sewer odour or repeated backups help the specialist understand the pattern.
- Ask others to stop water use: In a multi-unit or rental property, one person using water upstairs can worsen a lower-level backup.
Sewage exposure is not a fitness or toughness issue. Even people who invest in personalized health testing and coaching should treat contact with wastewater as a contamination risk, wash exposed skin well and avoid handling contaminated material without proper protection.

What TAP TECH does when we arrive
TAP TECH is not a general plumbing company. Drains and sewers are all we do. It is the equipment many plumbers and contractors call for when a drain or sewer line needs cleaning, jetting, descaling or camera inspection.
A trained emergency sewer and drain specialist focuses on stopping the backup, finding the cause and explaining what the pipe condition shows. The process is clear and practical:
- Confirm the symptoms and safe access: The specialist checks where sewage is appearing, which fixtures are affected and where the drain can be accessed safely.
- Quote the flat-rate price before work begins: There is no meter running and no surprise hourly billing.
- Inspect before recommending: A sewer camera inspection uses a small waterproof camera to show the inside of the pipe, including roots, scale, grease, sags or offset joints.
- Clear the line with the right method: Cabling uses a rotating cable to open a blockage. Hydro jetting uses controlled high-pressure water to clean heavier buildup. Descaling removes hard internal scale from older cast iron or galvanised lines.
- Show what was found: You see the condition of your own pipe, so the recommendation is based on evidence, not guesswork.
If the camera shows a condition that requires pipe repair or replacement, TAP TECH explains what is visible and refers that work out. Our role is to clear, clean and inspect drains and sewer lines.
When can you use water again?
Do not restart normal water use just because the water level drops. A partial blockage can let water seep past slowly, then back up again once another large volume enters the line. Wait until the main line has been cleared and the specialist confirms that water is moving properly.
Once the line is open, water use usually restarts in a controlled way. The specialist may run a fixture briefly while watching flow, then confirm that the drain is carrying water as expected. If roots, scale or grease caused the blockage, you may also be shown why cabling alone may not hold for long on that line.
For Kingston homes with repeated backups, especially older properties connected to municipal sewer, a camera inspection can help separate a simple blockage from a pattern that needs maintenance cleaning, hydro jetting or descaling.
Frequently asked questions
Can I flush the toilet just once during a sewer backup? No. One flush can add enough water to push sewage out through the lowest drain. Leave every toilet unused until the line has been cleared.
Can I shower if the backup is only in the basement? No. The shower water still drains into the same system. If the main line is blocked, that water can return through the basement floor drain, tub or shower.
Is it safe to pour drain cleaner into the backed-up drain? No. Chemical drain cleaner may sit in the pipe, mix with sewage and create a hazard for the person clearing the line. It also will not remove roots, heavy scale or many main line blockages.
What if the sewage goes down on its own? Treat that as temporary relief, not proof the problem is gone. A partial blockage can drain slowly, then back up again when laundry, showers or toilets add more water.
