Ottawa Residential Protective Plumbing Program

The City of Ottawa’s Residential Protective Plumbing Program provides financial assistance to eligible property owners installing approved flood-protection devices, including sanitary and storm backwater valves. These devices can help reduce the risk of wastewater or stormwater entering a home when water levels rise within the municipal sewer system.

Eligible homeowners may receive a rebate toward qualifying installation costs, but the program does not automatically cover the full cost of every project. Eligibility, available rebate amounts and documentation requirements depend on the property and the type of protective plumbing being installed.

A building permit must be obtained before work begins. Once the installation is complete, the City must inspect the work, and the homeowner must submit the required permit, inspection and paid-invoice documentation within the applicable timeframe. John The Plumber provides hands-on assistance with the permit process and Residential Protective Plumbing Program paperwork to help Ottawa homeowners navigate these requirements.

What Is a Backwater Valve?

🛡️ Flood Protection

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.

How a Backwater Valve Works
💧 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

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!

Do I need a permit to install a backwater valve in Ottawa?

In many cases, yes. Backwater valve installations often require a plumbing permit through the City of Ottawa. Our team can help you with the permit application process, coordinate the required documentation and ensure the installation meets applicable code requirements.

Can you help me apply for the City of Ottawa's backwater valve rebate?

Yes. We regularly assist homeowners applying through the Residential Protective Plumbing Program. We help with the required paperwork, supporting documentation and installation details to make the rebate application process as straightforward as possible.

Which Ottawa neighbourhoods do you install backwater valves in?

We install backwater valves throughout Ottawa, including Barrhaven, Kanata, Nepean, Orléans, Gloucester, Stittsville, Vanier, Alta Vista, Beacon Hill, Riverside South and surrounding communities. If you're unsure whether we service your area, just give us a call.

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

Many homeowners consider installing a backwater valve after experiencing a basement sewer backup or when finishing a basement. We also recommend discussing backwater valve protection if your property has experienced flooding during heavy rainfall or is located in an area where sewer backups have occurred.

How long does a backwater valve installation take?

Most residential installations are completed in a single day, although the exact timeframe depends on your home's plumbing layout, the accessibility of the main sewer line and whether additional drain modifications are required.

Will my basement floor need to be opened?

Yes, in most cases. Because the backwater valve is installed on the home's main sanitary sewer line beneath the basement floor, a section of concrete is typically removed to access the pipe. Once the installation is complete, the floor is professionally restored.

Do backwater valves require maintenance?

Yes. Like any mechanical plumbing device, a backwater valve should be inspected and cleaned periodically to ensure the flap moves freely and continues to protect your home during a sewer backup. Our plumbers can explain the recommended maintenance after installation.

Can you inspect my home to see if a backwater valve can be installed?

Absolutely. We'll inspect your existing drainage system, determine whether your home is a good candidate for a backwater valve and explain any permit requirements, installation options and available flood protection measures before any work begins.
