Approved Backflow Prevention Devices

Title 17 of the California Code of Regulations requires public water systems to use backflow prevention devices that have been laboratory and field tested by a recognized testing organization that has demonstrated its competency to the Department. The University of Southern California's Foundation for Cross-Connection Control and Hydraulic Research is one such organization. USC's Foundation maintains a list of approved devices on its website at: http://fccchr.usc.edu/list.html.

Please note that USC's approved device list includes those devices certified as "lead-free", as well as those aren't. Pursuant to Health and Safety Code Section 116875, if the water flowing through a backflow prevention device is ultimately provided for human consumption, the device must be lead-free. Those selecting a device should be cognizant of this requirement and choose accordingly.

If you need additional assistance, please contact the Division of Drinking Water at (916) 449-5577.
