Does the City of Delta require annual backflow testing?

Backflow prevention assemblies subject to City of Delta requirements must be tested annually by a qualified certified tester. Testing is also required immediately after an assembly is relocated, replaced, repaired, cleaned internally, or affected by alterations to its supplying piping.

Do you submit the required reports to the City of Delta?

Yes. After completing the certified backflow test, 123 Backflow prepares and submits the applicable test report through the City of Delta's online reporting process.

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

Yes. 123 Backflow provides certified services for warehouses, logistics centres, industrial and manufacturing facilities, farms, irrigation systems, commercial buildings, strata corporations, restaurants and other Delta properties.

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?

Applicable backflow prevention assemblies in Delta must be tested annually and immediately after relocation, replacement, internal cleaning, repair or relevant alterations to the supplying piping.

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 manufacturer-approved 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 components are available and the repair is straightforward.
