Tacoma Water (Tacoma Public Utilities): backflow test rules

  • Who must test. Tacoma Water requires a Washington-certified backflow assembly tester (BAT) to inspect assemblies after installation and test them every year, and requires a copy of each test report. Source.
  • Notices and deadlines. Customers can join a free reminder program; Tacoma Water then tells the customer's preferred BAT when the annual test is due and handles results with the BAT directly. Source.
  • How the report is filed. Tacoma Water publishes a downloadable backflow assembly test report and instructions for completing it; customers in the reminder program do not have to send results themselves. Source.
  • Tester registration. Any Washington-certified BAT may test. A BAT not on Tacoma's list must provide current state certification and test equipment calibration certificates, or Tacoma will not accept the reports. Source.
  • Approved testers. Tacoma Water shows its authorized backflow assembly tester list on the program page, and testers join through a participation form. Source.
