Backwater Valve Installation
Protect Your Basement from Sewage Backups
Storms, clogged sewers, or blockages can cause wastewater to back up into your home — damaging your basement, belongings, and air quality.
Installing a backwater valve is one of the smartest ways to prevent that.
At UPR, we specialize in professional, code-compliant backwater valve installations for both new builds and existing homes across Toronto and surrounding areas.
What Is a Backwater Valve?
Also known as a backflow preventer, sewer backup valve, or mainline backwater valve, this device is installed in your home’s main sewer line to stop wastewater from flowing back into your home.
How It Works:
Under normal conditions, the valve flap stays open, allowing water to flow out of your home.
During heavy rain or a backup, the flap is lifted by flotation devices and seals the pipe.
Once the pressure drops, the flap reopens, allowing flow to resume normally.
This simple but powerful mechanism prevents sewer water from flooding your basement, saving you thousands in cleanup and repairs.
