5. Who can install a backflow device?: Anyone can install a device; however, District approved Riverside County Certified Testers are responsible for performing accurate tests, and repairing or replacing devices that fail. Additionally, testers must report all repairs and test results to Rancho Water. The tester is required to give a copy of the completed test report to the customer and fax it to (951) 296-6865 or send the original to Rancho California Water District: 42135 Winchester Road, Temecula, CA 92590.

6. How can I protect the backflow device against theft and vandalism?: By installing cages, decorative rock covers, or blending it with shrubbery around the device. Be sure to leave 24 inches of clearance for annual testing. Painting the device may be an option. This can deter thieves since it devalues the metal.
