Here is a list of approved backflow testers.
If you are interested in being certified as a backflow prevention device tester, the backflow written exam is offered Monday through Friday in our downtown Riverside office located at 3880 Lemon St., Suite 200. Testing times are 8:30am or 1:30pm.
You may fill out the Backflow Tester Application and fax your application to (951) 955-8988 or email it to the Land Use Department, then call (951) 955-8980 to make your payment (MasterCard or Visa only). Payment and application can also be brought on the day of the test. Please arrive at least 20 minutes prior to the scheduled testing time in order for us to process your application.
Written exams must be completed at least 3 weeks prior to the next hands-on exam. Once a new tester's application is received, the written exam must be completed within 30 days or the application will expire. Fees are non-refundable.
