Backflow Prevention Testing in Burnaby & Metro Vancouver: What Property Owners Must Know
The short version — Across Metro Vancouver, properties with backflow preventers must have them tested at least once a year by a certified tester, with the test report filed to the municipality (often within 10 days). Programs are administered locally — Burnaby, Vancouver and other cities each run a Cross-Connection Control Program and may charge an annual review fee. Missing a test can mean penalties or a water shut-off.
Backflow prevention is one of those requirements most homeowners never hear about — until they get a notice from the city. If your property has a backflow preventer (common with irrigation systems, boilers, fire lines, and many commercial and multi-family connections), annual testing is almost certainly mandatory. Here is how it works in Metro Vancouver.
What backflow prevention actually does
A backflow preventer stops contaminated water from being siphoned backward into the clean drinking-water supply when pressure drops — for example, during a water-main break or heavy fire-line draw. Municipal Cross-Connection Control Programs exist specifically to protect the public water supply from these “cross connections.”
How often must it be tested?
Backflow assemblies must be tested at least once per year, no later than the anniversary date of the previous test. Many municipalities mail the property owner a notice shortly before the due date, but the legal responsibility to test on time rests with the owner.
Who can test it — and the reporting deadline
- Testing must be performed by a certified backflow assembly tester (certification in BC is managed through the BC Water & Waste Association).
- The tester completes the municipality’s official test report form and submits it to the city’s Cross-Connection Control department — in Burnaby, within 10 days of the test.
- Cities such as Burnaby may charge the property owner an annual review fee for processing the report.
What happens if you skip it
Municipalities keep records of every registered device and its due date. Miss the test and you can face penalties, repeated notices, and — in persistent cases — disconnection of the water service until compliance is restored.
