Vancouver backflow test deadline
Within 15 days of the test. That is the City of Vancouver's rule, quoted below from its own bylaw. Put in your building and your date, and you get the day it is due.
The rule, in the City of Vancouver's words
“the results of all backflow prevention assembly tests are recorded by a certified backflow assembly tester on a test report form that is approved by the Engineer, signed by the tester, and submitted within 15 days of the test”
Bylaw — Water Works By-law No. 4848, s.4.11(c) · read 26-Sep-2026
Worth knowing: $30 per report, charged to the tester and set in the by-law itself (Schedule H). This is the authority-funded pattern running in Canada: a private vendor holds the filing channel and bills the tester per report.
What happens next
- Check your date above. The answer appears on this page straight away: the day your report is due, or which date we still need.
- If you leave your email (and tick “I would like a quote” if you want a price), a person replies in writing, usually the same day. Nothing is charged and nobody calls.
- A certified tester tests every device on the notice, annually.
- The report reaches the City of Vancouver inside the window. Reports go to the BSI Online portal, which BSI runs on behalf of the City (questions: backflow@vancouver.ca). Keep the confirmation, not only your sent copy.
