Does Langley require annual backflow testing?

Properties equipped with testable backflow prevention assemblies are generally required to complete certified annual testing under the requirements of the City of Langley or Township of Langley.

Do you submit reports to the City of Langley and Township of Langley?

Yes. After completing the certified backflow test, 123 Backflow prepares and submits the applicable test documentation to the appropriate Langley municipality.

Do you provide backflow testing for warehouses, industrial buildings and agricultural properties?

Yes. 123 Backflow provides certified services for warehouses, industrial facilities, agricultural operations, irrigation systems, commercial buildings, strata corporations, restaurants, retail businesses and other properties throughout Langley.

How long does backflow testing take?

Most backflow preventer tests take approximately 20 to 45 minutes per device, depending on the assembly's type, size, location, accessibility and condition.

How often should a backflow preventer be tested?

Testable backflow prevention assemblies are generally tested when installed and annually afterward. Additional testing may be required following repair, replacement, relocation or other corrective work.

What happens if my backflow preventer fails?

A failed assembly does not always require complete replacement. Depending on its condition, it may be repaired using suitable replacement components and then retested to verify proper operation.

Can you repair the device during the same visit?

In many cases, repair and retesting can be completed during the same visit when the required parts are available and the repair is straightforward.
