What is a Backwater Valve?
A backwater valve (backflow prevention valve) blocks sewage from backing up into your home during heavy rain or sewer system overloads.
How it works?
Installed in your basement floor on the main sewer line
Contains a flap that opens to allow wastewater to flow out
Automatically closes when water tries to flow backward
Prevents city sewer backup from entering your home
Why Oakville Homes Need a Backwater Valve
Aging combined sewer system prone to overflows
Increasing frequency of heavy rainfall events
Many older homes lack backflow protection
Insurance may require or reward having one installed
Types of Backwater Valves We Install

Opens only when water flows out, providing maximum protection against backflow.
Normally Open Valve
