Backwater Valve Installation · Burlington
Backwater Valve Installation for Burlington homeowners.
Halton currently supports eligible interior backwater valves at 50% of eligible costs up to $1,600; exterior installations are not eligible.
A backwater valve is designed to close when wastewater reverses direction in the sewer lateral. The valve must be placed on the correct pipe, remain accessible and be installed as part of a system that accounts for stormwater connections upstream.

What we review
Fit the installation to the home and the local rules.
- Review of the sanitary and storm drainage layout
- CCTV inspection or verification where required by the programme
- Indoor or outdoor installation planning based on local rules and site conditions
- Permit, inspection and product documentation
Halton Basement Flooding Prevention Subsidy
Current enhanced limits include up to $6,500 for eligible weeping-tile disconnection with sump-pump installation, $1,600 for an eligible interior backwater valve and $900 for eligible downspout disconnection.

Does backwater valve installation qualify for the Burlington programme?
Eligibility depends on the property and current programme rules. Halton currently supports eligible interior backwater valves at 50% of eligible costs up to $1,600; exterior installations are not eligible. The municipality or region makes the final decision.
Do permits or inspections apply?
They may. We review the relevant municipal requirements and keep permit and inspection records when they are part of the project.
What is the first step?
Call Flood Ready and describe the home, past flooding and existing equipment. We can then determine whether an assessment or programme review should come first.
