What is a Backflow Valve?

Also called a backflow prevention or sewer backup valve, a backwater valve is a one-way valve in your main sewer line that keeps sewage out of your home during storms or sewer surges.

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 Brampton 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

Types of Backwater Valves We Install

Normally Closed Valve

Opens only when water flows out, Best used for branch lines and not main line sewer.

Normally Open Valve

Stays open during normal use, closes when backflow is detected. Most common type.

Full-Port Gate Valve

Most Common Sewage Backup Causes in Brampton Understanding the risks helps you see why thousands of Brampton homeowners are installing backwater valves.

Heavy Rainfall Backups

Municipal System Overloads

Even on dry days, city sewer issues like maintenance, blockages, or capacity limits can cause basement backups.


Our Solution

Even if the city sewer system fails, your home remains safe and secure.

Aging Infrastructure

Some older parts of Brampton have aging sewer infrastructure, which can be more prone to failures and sewer backups.


Our Solution

Protect your home independently instead of relying on old city sewer systems.

Tree Root Intrusion

Roots from nearby trees can clog sewer lines, leading to backups that affect your home and your neighbors’.
