Backflow Testing in Downtown: where the assessment starts

Diagnosis and repair options
The tester identifies the assembly, records its make and serial number, and measures its performance with test equipment. A passing test documents the condition of that assembly on the test date; it does not certify every pipe or fixture at the property.
If an assembly fails, the next step is to identify the failed component, discuss repair or replacement, and retest the assembly. The test report and any follow-up work should identify the same device and property.
Ask which testing, reporting and repair charges are included. The water provider’s requirements and the assembly’s condition determine the work; a reminder letter alone does not mean the device needs replacement.
Backflow Testing Process in Downtown
Locate and identify the assembly
We locate the backflow preventer, record the assembly type, manufacturer, and serial number for the PWB submission.
Perform the certified differential pressure test
Using calibrated test equipment, we measure the differential pressure across the assembly to verify both check valves seat properly and the relief valve opens at the correct pressure.
Repair if the assembly fails
Failed check valves or relief valve components repaired or replaced on site when parts are available — most common repair parts are stocked on the truck.
Submit results to Portland Water Bureau
Test results submitted directly to PWB's cross-connection control program. You receive a copy and a reminder for next year's annual test.

Preparing for a visit in Downtown
Have the water provider’s reminder letter, assembly location and any previous test report ready. Tell us whether the device serves irrigation, a fire system or another connection, and whether a brief water interruption needs to be coordinated.
If the property has shared building systems, arrange a management contact, unit access and approval for any shared shutoff. A fault in one unit should be distinguished from a building-wide problem before work is authorized.

Common questions about backflow testing in Downtown, Portland.
Can a plumber perform backflow testing or does it require a specialist?
Oregon requires backflow testing to be performed by a state-certified backflow assembly tester. We hold Oregon backflow tester certification and submit results directly to the Portland Water Bureau's cross-connection control program.
Who needs backflow testing in Portland?
Portland Water Bureau requires annual backflow preventer testing for: irrigation systems connected to city water, commercial properties with cross-connection hazards, residential fire suppression systems, and any property with a reduced pressure zone (RPZ) assembly. Most residential properties without irrigation don't require annual testing.
How much does backflow testing cost in Portland?
The price depends on diagnosis, access, parts and the agreed work. Ask what is included in the assessment and request the repair scope and price before authorizing work. Additional restoration or specialist work should be identified separately.
What is a backflow preventer?
A backflow preventer is a mechanical device that allows water to flow in one direction only — from the city main into your property — and prevents any contaminated water from flowing backward into the public supply. Oregon requires them at cross-connection points to protect public water quality.
What happens if my backflow preventer fails the test?
A failed backflow preventer must be repaired or replaced and retested before the results can be submitted to Portland Water Bureau. We repair assemblies on site if parts are available, or schedule a return visit and retest.
