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://www.usc.edu/dept/fccchr/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 Drinking Water Program at (916) 449-5600.
