FAQ
Backflow testing FAQs — Oregon & Washington
Common questions from property managers and facility directors.
Is backflow testing required for fire sprinkler systems in Oregon?
Yes. Portland Water Bureau and most Oregon water authorities require annual backflow testing for all fire sprinkler system connections to the potable water supply. Failure to test can result in service interruption or fines from your water purveyor.
What is the difference between an RPZ and a double check valve assembly?
An RPZ (Reduced Pressure Zone) assembly provides the highest level of backflow protection and is required for high-hazard connections like those in healthcare or industrial settings. A DCVA (Double Check Valve Assembly) is used for lower-hazard connections. Your water authority determines which device is required for your specific connection.
Who receives the backflow test report in Oregon?
PDX Fire Protection submits test reports directly to your local water purveyor — Portland Water Bureau, Tualatin Valley Water District, Clackamas River Water, or Clark Public Utilities in Washington. We also provide a copy for your property records.
What happens if a backflow device fails testing?
A failed device must be repaired or replaced and re-tested to restore compliance. Your water authority may place a hold on water service if the failure isn’t addressed promptly. We complete repairs and re-test as quickly as possible to minimize that window.
How often does backflow testing need to be performed?
Most backflow prevention devices require annual testing. Some jurisdictions or high-hazard systems may require more frequent testing. We track your schedule and send reminders so you’re never out of compliance.
