Current program amount
For eligible work completed on or after November 12, 2025, the City offers up to 80% of invoiced cost to a maximum of $1,600 per device, for up to two backwater valves.
Key process
The City requires a building permit and inspection for backwater-valve installation. The property, contractor, invoices and other program conditions must satisfy the official requirements.
What our documentation support can include
- Clear itemized scope and valve location.
- Permit and inspection coordination information.
- CCTV or plumbing-assessment records when part of the project.
- Paid invoice and installation photographs.
- Manufacturer and maintenance information.
Verify before work: amounts, deadlines and eligibility can change.
Questions
Does the contractor approve the rebate?
No. Only the responsible municipality or region can determine eligibility, approve the application and issue payment.
Should work begin before reading the program rules?
No. Some programs require pre-approval or technical review, and the chosen valve location may affect eligibility.
What records should I keep?
Keep the quote, permit, CCTV or drainage records, paid itemized invoice, inspection approval, photographs and any program forms requested by the authority.
