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 Hawthorne
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 Hawthorne
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.
For a property with more than one living space, identify which fixtures share the problem and who can approve access. If a finished wall hides the line, describe the symptom first rather than opening the wall before diagnosis.

Common questions about backflow testing in Hawthorne, Portland.
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.
How do I submit backflow test results to Portland Water Bureau?
We submit test results directly to Portland Water Bureau on your behalf as your certified tester — you don't need to handle the paperwork. You receive a copy of the results for your records.
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.
