FAQs: Toilet backup

Why is my toilet backing up but other fixtures are fine?

This usually points to a toilet trap or nearby branch line obstruction (wipes, paper, foreign object). Start with a closet auger; if it repeats, we’ll pull the toilet and snake the branch, then camera to confirm the line is clear. See Toilet Repair.

“Flushable” wipes caused a clog—will it come back?

Wipes often mat and re-block lines. We’ll clear the clog and, if it’s recurring, run a camera to check for rough pipe walls, offsets, or roots that catch debris. Ongoing issues may benefit from Drain Cleaning with hydro jetting for a longer-lasting result.

When do you pull the toilet instead of snaking through the bowl?

If we suspect a foreign object (toy/brush) or repeated backups after augering, we’ll pull the toilet, clear from the underside, and replace the seal. This avoids pushing the object deeper. Learn more: Toilet Repair.

Could heavy rain cause a toilet to back up?

Yes—if the main sewer surcharges, you may see bubbling at the floor drain and multiple fixtures affected. That scenario needs mainline clearing + camera and possibly a backwater valve quote. Start with our Sewer Backup — First-Hour Checklist.

How do you prevent toilet clogs from coming back?

We often start with a camera inspection to assess roots, collapse, or debris, then install the valve if the lateral is suitable.

What if my downspouts connect to the sanitary line?

Use only toilet paper, avoid wipes and hygiene items, and consider an annual branch/mainline service if you’ve had repeats. A camera inspection can spot root intrusions, bellies, or offsets that catch waste—see Plumbing Inspections & Cameras.

Can you fix this today? What areas do you cover?

Yes—same-day slots are often available. We cover Hamilton, Burlington, Ancaster, Dundas, Stoney Creek, Grimsby, Niagara Falls, Binbrook, and Caledonia. Call 905-928-6831 or Book Online via Emergency Plumbing.

Plunger didn’t work—should I try chemical drain cleaner?

We don’t recommend it. Chemicals can damage finishes and traps and are hazardous when mixed with plunging/snaking. A professional auger or power snake is safer and more effective. Book a visit via Emergency Plumbing for urgent cases.
