Annual Testing

The District requires annual testing of backflow prevention devices installed on water service lines for domestic use, irrigation, and fire sprinklers.  Backflow devices on fire service lines also are required to have meters that are inspected regularly to ensure proper working order.  See Backflow/Cross Connection Requirements for more information.

Becoming A District-Approved Backflow Tester

The District provides customers with a list of approved backflow testers. Testers are required to enter tests electronically and can access the database through the DSRSD Tokay Test Entry Website

To be included on the District’s approved backflow testers list, each tester must turn in their application, backflow tester wall certificate, wallet card, and test kit calibration certificates annually by February 15, and attend a training session to use Tokay if they have not attended before.  Please contact Florence Khaw at khaw@dsrsd.com or 925-875-2238 regarding training.

Testers are required to have their test gauge equipment calibrated annually and submit proof of calibration with their application form. Approved testers must be certified by AWWA, NCBPA, or a similar certification program that is approved by the District.

Backflow Test Reports

The District sends notices to customers when their backflow prevention devices are due for testing. The notice includes test report due dates and a list of backflow assemblies with serial numbers and locations. For tester's use, a blank DSRSD test report form is available to download for any new backflow assembly installations.  For all existing backflow assemblies, the Tokay test entry website must be used to submit tests.
