Backflow test report for Canada (CSA B64.10)
Municipal backflow forms in Ontario, BC and Alberta share the CSA B64.10.1 readings: the check valve pressure drop (A), the relief valve opening point (B) and the buffer C = A − B. This report records all of them, works out the buffer for you, and has room for the owner’s signature many cities ask for.

What the report records
Type of test, municipality, facility or device ID, hazard level (severe, moderate or minor) and protection type. Then the device: make, model, type, serial, size, install date, location and orientation. The test covers static line pressure and both shut-off valves, then CV1 pressure drop (A), relief opening (B) and buffer C for RPs; check valve readings, spring tension loss and sight tube confirmation for DCVAs; and the air inlet and check for PVBs and SVBs. A failed test adds repairs and a re-test. It closes with your certifying body (OWWA, BCWWA or AWWA), certificate number, test kit calibration, and tester and owner signatures.
Deadlines differ by city
Toronto, Calgary, Edmonton and Vancouver each set their own submission window, from about 5 business days to 15 days, and several take reports only through a portal. Use your municipality’s form or portal for filing. This report is the customer’s signed copy and your own record, with the next annual test on your call list.
Built from the published forms
The field list comes from municipal forms published in Ontario and BC that follow CSA B64.10.1. It isn’t a municipal or CSA document, and the CSA standard itself isn’t reproduced.

About this template
Will my municipality accept this report?
Many require their own form or portal, so check with yours. This report contains the readings those forms ask for, which makes filing a copy-over job, and the owner gets a signed copy on site.
Does it calculate the buffer?
Yes. Enter the CV1 pressure drop (A) and the relief valve opening (B), and buffer C = A − B appears on the report, for the initial test and the re-test.
Can I use kPa?
Readings print in psi by default. You can rename a unit in your template, and a kPa option is planned for Canadian accounts.
