What is a Backwater Valve?
Also known as a backflow valve or sewage backup preventer, a backwater valve is a specialized one-way device we install on your property's main drainage line. With over 27 years serving Burlington homeowners, Canada Waterproofers has seen firsthand how these valves prevent costly sewage backups during severe rainfall events and city sewer system capacity issues.
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 Burlington Homes Need One
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
What types of Backwater Valves We Install
