What is commercial backflow and why my business needs it?

Ottawa’s backflow expert

What is a backflow?

Backflow is the unwanted flow of contaminated water reversing into your clean potable water supply system.

What causes backflow?

Backflow is typically caused when there is an abnormal drop in water pressure coming from your home or commercial/ industrial business and contaminate water is siphoned back into your clean water supply. This is typically referred to as back-siphonage and/or back pressure.

There is no doubt that backflow is extremely dangerous because it can allow drinking water in plumbing systems to become contaminated and unusable.

Why my business needs It?

Have you ever imagined not being able to use water in your business? What would you do?

If the water on your property is contaminated, you may have to close until the pipes are repaired. But every day that passes from being closed is a blow to your profitability and prevents you from serving your customers.

To avoid a headache, make sure you have a commercial backflow prevention plan.


  • At Tourangeau Mechanical, we test all our backflows in compliance with the B64.10-11/B64.10.1-11 (CSA Standards).
  • We are registered with Ontario Water Works Association (OWWA).
  • We have 3 to 5 backflow testers at all times.
  • Our testing gauges are calibrated every year as per  Canadian Standards Association (CSA) Standard requirements.

2. Repairs

  • Every device is inspected thoroughly by our experienced tester to confirm its failures.   
  • Failure is often cause by debris. Sometimes the devices can simply be cleaned to get a passing result. However, debris and water hammer can damage the internal parts causing failure.

3. Installation

  • All installations are done as per CSA and Local Standards.
  • Every installation is different due to site conditions and must be looked at to provide a proper quote.

The backflow prevention program keeps Ottawa’s drinking water safe

City of Ottawa

Under the new Ottawa bylaw or what municipalities across Ontario are calling the Backflow prevention program, owners will be needing to install backflow device and perform annual backflow testing and maintenance to ensure water the City’s potable water supply is safe from contaminants.
Backflow prevention programs are already mandated across many Ontario municipalities, including Toronto, Hamilton, London, Markham and Waterloo.

Approximately 14,000 commercial, and industrial buildings and homes in Ottawa will require an assessment (backflow prevention survey) to determine the level of risk. Severe and moderate risk buildings will be required to install a backflow prevention device.

Tourangeau Mechanical has 20+ years of Backflow Testing experience and currently tests over 700 backflows annually in the Ottawa area. We will work with owners across the Ottawa valley to test and install backflow prevention devices.

Complying with the new Ottawa backflow prevention program bylaw

City of Ottawa

The City of Ottawa’s Backflow Prevention Program protects drinking water quality by ensuring the appropriate installation and inspection of devices that prevent contaminated water from flowing back into the City’s water distribution system.

The City of Ottawa Backflow Program came into effect on June 28, 2017.

The program will effect around 15,000 industrial, commercial properties in the Ottawa area that are at risk of backflow incidents.

  • Owners with severe backflow incidents will have 1 year to complete a site survey and 1 year to install backflow devices.
  • Owners of moderate backflow incidents will have 1 year to complete a site survey and 2 years to install backflow devices.

Backflow Prevention Survey

If you receive a letter from the City of Ottawa, you must hire a certified backflow surveyor to perform a building survey. Once this has been completed the City will confirm and approve the survey.

Depending on the outcome of the survey, the City of Ottawa will determine what device, if any, needs to be installed within a certain time frame.

A survey will be required every 5 years to make sure the building does not change classification.

Tourangeau Mechanical can help every step of the way, from the backflow survey, installation of a new device to annual backflow testing.
