Important Info:

Any individual in Los Angeles County engaged in the business or occupation of testing, repairing or installing backflow prevention devices must become a Certified Backflow Tester. The certification process and monitoring of testers is performed by the Cross Connection and Water Pollution Control Program.

To become a Certified Backflow Tester, an individual must take and pass a practical examination every two years. They are required to demonstrate their ability to test double check valve assemblies, test reduced pressure principle backflow prevention devices, inspect pressure type vacuum breakers, and evaluate spill resistant pressure vacuum breakers. Upon successful completion of the examination, the certification is valid for a two year period. To qualify for the examination, an applicant must have the necessary knowledge to test backflow prevention devices and either be employed by a California State Licensed Contractor or possess a State Contractor’s License.

Upon receipt of backflow tester application and fee payment, an examination date will be scheduled. Exams are administered approximately three times per month, on Wednesdays, in the Backflow Testing Laboratory at the Environmental Health administrative headquarters in Baldwin Park.

The fee for taking the Certified Backflow Tester Examination is $296.

The biennial review fee is $296.
