DSRSD Backflow Testing Info

ANNUAL TESTING

The DSRSD mandates yearly testing of backflow prevention devices on water service lines for domestic use, irrigation, and fire sprinklers. Backflow devices on fire service lines must also have regularly inspected meters to ensure they function correctly. For more details, refer to the Backflow/Cross Connection Requirements.

BECOMING A DISTRICT-APPROVED BACKFLOW TESTER

The DSRSD has a list of approved backflow testers for customers. These testers must submit their test results online through the DSRSD Tokay Test Entry Website. To be added to the approved list, testers must submit an application, a backflow tester wall certificate, a wallet card, and test kit calibration certificates by February 15 each year. If they haven’t attended before, they must join a Tokay training session. For training questions, Call 925-875-2238. Testers must also calibrate their test equipment every year and provide proof with their application. To get approved, testers need certification from AWWA, NCBPA, or another District-approved certification program.

BACKFLOW TEST REPORTS

The DSRSD Backflow Testing informs customers when their backflow prevention devices need testing. The notice provides test report due dates and a list of backflow assemblies with serial numbers and locations. A blank DSRSD test report form can be downloaded for new installations. For existing assemblies, testers must use the Tokay test entry website to submit tests.
