Backflow prevention devices protect a building's drinking water supply from being contaminated by wastewater or non-potable water flowing in the wrong direction, and many commercial properties in Toronto are required to have these devices tested on a regular basis under the city's cross-connection control requirements. We test and inspect backflow prevention assemblies for restaurants, offices, medical units, and other commercial properties across Scarborough.
Backflow testing is a straightforward process for us, but it needs to be done correctly and documented properly so the results can be submitted where required. We work with property managers and business owners to schedule testing with as little interruption to water service as possible, and we explain any deficiencies found so they can be addressed promptly.
Whether your property is a stand-alone retail unit on Lawrence Avenue or part of a larger plaza near Kennedy and Ellesmere, we approach every backflow test the same way: methodically, with clear documentation of the results.
Signs You Need Backflow Testing
Reasons a Scarborough business typically needs backflow testing:
Annual testing requirement
Many commercial properties with backflow prevention assemblies are required to have them tested on a yearly basis to confirm they're functioning properly.
New or replaced device
A newly installed backflow preventer should be tested before it's relied on to confirm it's operating as intended.
Property management or insurance request
Property managers or insurers sometimes request current backflow test documentation as part of routine building compliance.
Change in water use or fixtures
Adding equipment such as irrigation systems, boilers, or specialized kitchen fixtures can introduce new cross-connection risks worth reviewing.
Visible signs of a failing device
Leaking, dripping, or unusual noise from the backflow assembly can indicate internal components aren't sealing properly.
No record of recent testing
If a property doesn't have documentation of a recent test, it's worth having the device checked to confirm its condition.
How We Do It
How we carry out backflow testing:
Step 1: Reviewing the device and location
We locate the backflow prevention assembly and confirm the make and model before beginning the test.
Step 2: Isolating the water supply
We shut off water to the section being tested, coordinating timing with staff so the interruption is as brief as possible.
Step 3: Performing the test
Using calibrated test equipment, we check each check valve and relief mechanism within the assembly for proper operation.
Step 4: Documenting the results
We record the test results in writing, noting whether the device passed or if any component needs repair or replacement.
Step 5: Restoring water service
Once testing is complete, we restore water flow and confirm the assembly is holding properly under normal pressure.
Step 6: Providing paperwork
We provide the completed test report so it can be kept on file or submitted to the property manager or relevant authority as needed.
Backflow testing for Scarborough businesses
Commercial properties along Victoria Park, Eglinton, and Kingston Road often include a mix of restaurants, medical offices, and light industrial units, each with different backflow prevention needs depending on the fixtures and equipment connected to the water supply. We take the specific setup of your property into account rather than treating every test the same way.
The City of Toronto has cross-connection control requirements that apply to many commercial and industrial properties, and testing is generally expected to be carried out periodically by someone qualified to do so. We're happy to discuss what applies to your specific property and help keep your testing on a regular schedule.

Backflow Testing FAQs
How often does a backflow device need to be tested?
Most commercial properties with these devices are expected to have them tested annually, though the exact requirement can depend on your property type and the city's current bylaw.
Will testing shut off water to my whole building?
Typically only the section of plumbing served by that specific backflow assembly needs to be isolated during testing, which we coordinate with you in advance.
What happens if my device fails the test?
We'll explain what component isn't functioning correctly and discuss repair or replacement so the device can be brought back into proper working order.
Do I need to submit the test report somewhere?
Depending on your property and any requirements that apply to it, you may need to keep the report on file or submit it to the city or your property manager; we provide the documentation either way.
Can you test multiple devices in one visit?
Yes, if your property has more than one backflow prevention assembly, we can test them all in the same visit to save time.
