  • Who must test. Backflow prevention assemblies must be tested once a year on the anniversary of the device's installation date. Irrigation, boilers, solar collectors, fire sprinklers, spas and pools typically need added protection. Source.
  • How the report is filed. The property owner is responsible for having the test done and making sure a copy of the test report is sent to the Public Works Department. No portal or deadline in days is stated. Source.
  • Tester registration. Devices must be tested annually by an Oregon Health Division certified tester. No separate city registration is stated. Source.
  • Approved testers. The program page links a city-hosted list of Certified Backflow Testers in the area. Format not confirmed. Source.
  • If a test is missed. If annual testing is not completed, Public Works notifies the owner; if the owner does not test, the City may turn off water service, and state law requires discontinuing service until testing is complete. Source.
