BACKFLOW VERIFICATION
Annual backflow-preventer verification
Coordinated annual testing, a clear record, and a known next due date.
WHY IT MATTERS
Protect the network. Document the verification.
A backflow preventer helps stop contaminated water from returning to the potable water network. In Quebec, certain devices must be tested at installation, after certain work or relocation, and then annually.
The owner must retain proof of testing. Norméo organizes the request and record; regulated testing is assigned to a backflow tester whose status is active in the provincial registry.
References checked August 19, 2026: RBQ, CMMTQ and Réseau Environnement’s VDAr registry. Exact application depends on the building and device.

WHO THE SERVICE IS FOR
Scope confirmed for the building and installation.
Requirements notably cover institutional, commercial and industrial buildings, as well as certain residential buildings. Specific equipment can also create a cross-connection risk.
You do not have to determine alone whether every device is in scope. Send the address and what you know; scope will be checked before scheduling.
IF A DEVICE FAILS
A clear result. A separate next action.
A failed result is not presented as compliant. The deficiency is documented. If plumbing work is required, it must be assigned separately to an authorized contractor; retesting follows correction.

What is a backflow preventer?
A backflow preventer helps stop contaminated water from returning to the potable water network.
Is annual verification required?
Certain in-scope devices are tested at installation, after certain work or relocation, and annually thereafter. Exact application must be confirmed for the building and device.
What if I do not know the device count?
Send the address and what you know. Type, serial number and exact count can be confirmed during scoping.
Who performs the testing?
Regulated testing is assigned to a backflow tester with active status in the provincial registry. Norméo coordinates the request and maintains the building record.
What happens if a device fails?
The result and deficiency are documented. Required plumbing work is a separate scope assigned to an authorized contractor, followed by retesting.
Do I receive a report?
Yes. Norméo service includes the available report, device history and next due date in a protected digital record.
Is the portal included?
Yes. It accompanies Norméo service and is not a separate software subscription.
How long does verification take?
Duration varies with device count, accessibility and installation condition. It is estimated when scope is confirmed.
