Complete Guide & Expert Installation
Prevent costly sewage backup damage with professional backwater valve installation in Burlington. Expert technicians with 15+ years of proven experience. City rebates help offset installation costs.
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
Normally Closed Valve
Opens only when water flows out, providing maximum protection against backflow.
Normally Open Valve
Stays open during normal use, closes when backflow is detected. Most common type.
Full-Port Gate Valve
Premium option with manual override and clear access cover for inspection.
Benefits of having a Backwater Valve Installed A small investment that provides significant protection for your home, health, and finances.
Sewage Backup Protection
Protects your basement from sewage backups during storms or overwhelmed sewer systems, keeping your home cleaner and your family healthier.

Common Sewage Backup Causes in Burlington Recognizing the dangers helps you see why countless Burlington residents are investing in backwater valve protection.
Heavy Rainfall Backups
Halton Region's municipal sewer network can exceed capacity during heavy rainfall events, pushing wastewater back up into your property's drainage system.
Our Solution ✅
A backwater valve automatically closes your sewer line during surges, preventing sewage from backing up into your home.
Municipal System Overloads
Even on dry days, city sewer maintenance, blockages, or capacity problems can lead to backups.
Our Solution ✅
Your home stays safe no matter what’s happening with the city’s sewer system.
Aging Infrastructure
Many established Burlington neighborhoods operate with 50-100 year old sewer lines susceptible to deterioration and backup events.
Our Solution ✅
Don’t leave your home at the mercy of old city infrastructure—take protection into your own hands.
Tree Root Intrusion
Tree roots can clog neighborhood sewer lines, leading to backups that impact several homes.
Our Solution ✅
A backwater valve shields your home from sewage issues caused by your neighbors’ plumbing.
