Understanding Ottawa's Rebate Program

Who Qualifies for Ottawa's Protective Plumbing Rebate?

Ottawa's Residential Protective Plumbing Program offers financial assistance for eligible new protective plumbing installations. Homeowners must meet the City's property, permit, inspection and application requirements.

Important: Obtain the required building permit before starting work. A qualifying new installation may still be eligible for a rebate after completion. Maintenance, repairs and replacement of existing protective plumbing devices are excluded.

Eligible Ottawa Properties

The property must be an eligible residential property within the City of Ottawa.

Property Age Requirements

Qualifying New Installations

The work must involve an eligible new installation. Maintenance, repairs and replacement of an existing device do not qualify.

Previous Rebates and Other Funding

Previous rebates for the property, including those received by former owners, may affect eligibility. Work funded through an excluded municipal or provincial program is not eligible.

Work Installed by the City

Protective plumbing installed by the City of Ottawa is not eligible for this rebate.

Approval and Available Funding

Applications are subject to City approval, program requirements and available annual funding. Funding is not guaranteed.

City Rebate Maximums

Eligible Work and Maximum Rebate Amounts

How the Application Works

Permit, Inspection and Application Steps

1

Assessment and Permit

Have the property assessed, confirm the proposed protective plumbing work and obtain the required building permit before installation begins.

2

Installation and Inspection

Complete the installation and arrange required City inspections. Underground plumbing must be inspected before being concealed, as applicable. Keep valve access covers reachable for maintenance.

3

Payment and Documentation

Keep proof of property ownership, the building permit, the applicable inspection report and a paid, itemized invoice for the work.

4

Submit the Rebate Application

Follow the City's current application instructions and submit all required documents within the deadline applicable to your permit. The City makes the final eligibility decision.

A CCTV sewer camera inspection may be recommended as an optional diagnostic service, but it is not itself a City rebate requirement. See the City's backwater valve permit guidance .

When Is the Rebate Application Due?

A City program update effective July 1, 2026 describes an 18-month period from the building permit issue date to complete the work and submit the rebate application.

However, older 12-month wording and a one-year deadline in published City materials have also appeared. Confirm directly with the City which deadline applies to your permit before relying on an extension.

What Is a Backwater Valve?

Understanding Backwater Valves

How a Backwater Valve Protects Your Home

A backwater valve is installed on your home's sanitary or storm sewer line to help stop wastewater or stormwater from flowing backward into your property during a sewer surcharge. During normal drainage, the valve remains open, allowing wastewater to flow safely away from your home.

If wastewater begins flowing back toward your property, the valve automatically closes to help reduce the risk of sewage entering through basement floor drains, toilets, showers, and other low-level plumbing fixtures. It's one of the most effective ways to help protect a finished basement from costly sewer backups.

💧 During normal drainage the valve remains open. If sewage begins flowing backwards, the valve automatically closes to help protect your home.
🏠
Professional Installation

Installing a backwater valve usually requires access to the main sewer line beneath your basement floor. Our licensed Ottawa plumbers install the correct valve in an accessible location while ensuring the work complies with Ontario Plumbing Code requirements and City of Ottawa standards. We can also assist with permit applications and available municipal program documentation where required.

🔧
Routine Inspection & Maintenance

Existing backwater valves should be inspected and cleaned regularly to ensure they operate properly when you need them most. Debris can prevent the internal flap or gate from sealing completely, while an obstructed access cover can make maintenance difficult. We inspect, clean, and service accessible components while identifying any issues that may require repair or replacement.

✅
Protect Your Finished Basement

Concerned about a previous sewer backup or simply looking to better protect your finished basement? Our experienced plumbers can assess your drainage system and determine whether a backwater valve installation or servicing is the right solution for your Ottawa home. Request a backwater valve assessment to discuss installation options for your Ottawa home.

Aaron Walker and the team provided excellent service. They set clear expectations about when they would be there, and were prompt. Their knowledge of backwater valves, and heir ability to communicate it, are excellent. The team was friendly/polite, conscientious, took great care in the prep and cleanup, and made me feel confident in the whole process and outcome. If you're considering a backwater valve to prevent basement flooding, you must call John The Plumber.

We've hired John the Plumber in the past and been super happy with those experiences. So we called them again after deciding it was a good idea to install a floor drain backwater valve. Just like in past, we were not disappointed. Garrett arrived on time and was super friendly. He even took time to warmly introduce himself to our nervous Mastiff, which made the entire visit much more enjoyable for everyone! Garrett was very personable and efficient. After he finished the floor drain installation he made sure to show me his work and also explained other plumbing features we recently had installed. Before leaving he made sure to emphasize the two-year service warranty, which I appreciated. Thanks so much Garrett! John the Plumber will definitely be our go-to plumbing company for years to come. They also have super reasonable rates. Highly recommend.

Had a mainline backwater valve installed in my basement. Connor, Miguel and Eric were very professional, courteous, clean and thorough. Everything you want when people come into your home to do a, potentially, dirty job. After the job was completed there was very little clean up required by me. Hats off to them. I would recommend them to anyone thinking of having this work done. Many thanks gentlemen!

How do I know if my Ottawa home should have a backwater valve?

Homeowners often consider a backwater valve after a basement sewer backup, when renovating a basement or when assessing sewer-backup risks.

A plumber can examine your drainage layout and determine whether a backwater valve is suitable. A properly installed valve can help reduce the risk of sewage flowing backward through the drainage system, but it cannot prevent every type of basement flooding.

How long does a backwater valve installation take?

The timeframe depends on your home's plumbing layout, access to the sewer line, required drain modifications, concrete restoration and City inspection scheduling.

We'll discuss the expected installation schedule after assessing the property.

Will my basement floor need to be opened?

For an indoor installation beneath the basement floor, a section of concrete usually needs to be opened to access the drainage pipe.

Confirm the floor-opening and concrete-restoration scope in your written quote. The valve's access cover must remain accessible for inspection and maintenance.

Do backwater valves require maintenance?

Yes. Backwater valves should be inspected and cleaned according to the manufacturer's recommendations. Debris can interfere with the valve's moving parts and reduce its effectiveness.

Our plumbers can explain the appropriate maintenance procedure after installation.

Can you assess my home for a backwater valve installation?

Yes. We can assess your existing drainage system, discuss whether a backwater valve is suitable and explain the installation options, permit requirements and proposed scope of work.

Request a backwater valve assessment to get started.

Can I apply for a rebate after my backwater valve has been installed?

Yes. A qualifying new installation may still be eligible for a rebate after the work has been completed, provided the City's requirements are met.

The required permit must be obtained before work begins, and applicable inspection, documentation and application deadlines must be satisfied.

Maintenance, repairs and replacement of an existing protective plumbing device are excluded from the rebate.
