Backwater Valve Installation in Ottawa

Ottawa Backwater Valve Rebates

Eligible new installations may qualify under the City of Ottawa's Residential Protective Plumbing Program. The property must be residential and within Ottawa, built before January 1, 2004 for storm protective plumbing or before January 1, 2012 for sanitary protective plumbing.

An eligible indoor sanitary or storm backwater valve may qualify for up to $1,000; an outdoor storm valve for up to $2,500. The plumbing building permit rebate is 100% of the current fee. Rebates cannot exceed eligible costs or the applicable City limit.

A qualifying new installation may still be eligible after completion if the permit was obtained before work began and the City's requirements are met. Maintenance, repairs and replacement of an existing protective plumbing device are excluded, as is City-installed work. Funding availability, previous rebates including those received by previous owners, and other approved municipal or provincial program funding affect eligibility.

After installation, required inspections and payment, submit the application with proof of ownership, the building permit, the Building Code Services inspection report and a paid, itemized invoice.

Deadline caveat: The City's update effective July 1, 2026 states that work must be completed and the application received within 18 months of the permit issue date. Older 12-month wording remains on the program page, and the published bylaw still says one year. Confirm the deadline for your permit with the City; do not assume how the update applies to an individual case.

Price Factors and Your Written Quote

Cost depends on the valve type and location, access and excavation, pipe depth and condition, required plumbing changes, floor restoration, and permit and inspection requirements. A site assessment is needed to define the work.

Ask the written quote to identify:

• The valve type, proposed location and plumbing work.
• Who obtains the permit and arranges inspections, and which fees are included.
• Floor opening, excavation, concrete restoration, finished-floor repairs, debris removal and cleanup responsibilities.
• How the maintenance cover will remain accessible and what care is recommended.
• Any optional diagnostics, exclusions, taxes and the approval process for additional work.
• The expected sequence, site-dependent schedule and applicable written warranty terms.
