Why Sewer Squad Is Toronto’s Go-To Plumbing Company
Your Best Defence Against Sewer Backups
When heavy rain overwhelms city sewer lines, sewage can surge back into your home. A backwater valve stops that cold. It’s a one-way gate that closes when water tries to flow the wrong way.
If your basement’s below street level or you’ve had a backup before, a backwater valve isn’t optional. It’s required by many cities and essential to qualify for rebate programs. We install, inspect, and maintain city-approved valves so your home stays protected and your rebate paperwork gets done right.
