Backwater Valve Installation in Toronto

A backwater valve is the single most effective fix for a home that has flooded from sewer backup before. We install, permit, and inspect it properly the first time.

24/7 Emergency Service Licensed & Insured Same-Day Appointments Camera Inspections Financing Available

If your basement has ever flooded because the municipal sewer backed up into your home, a backwater valve is the fix that actually prevents it from happening again. The valve sits on your main drain line and allows wastewater to flow out — but closes automatically the moment flow tries to reverse.

The City of Toronto offers a subsidy program to help homeowners cover the cost of backwater valve installation, and we handle the permit application and inspection requirements as part of the job, not as an extra hassle for you.

What's included in our installation

  • Camera inspection to confirm the ideal valve location on your main line
  • Excavation and installation of a code-compliant backwater valve
  • Permit application handling with the City of Toronto
  • Final inspection coordination so your subsidy application goes through cleanly

Who should install one

  • Homes with a history of sewer backup during heavy rain
  • Older homes on combined sewer systems in low-lying areas
  • Homes recently finished or renovated in the basement
  • Anyone renewing home insurance that requires flood-prevention measures
