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. Currently the District is working on improving backflow program efficiency and striving to go paperless by allowing testers to enter test results directly into the database. Testers are able to access the database through the DSRSD Tokay Test Entry Website.
To be included on the District’s approved backflow testers list, each tester must attend one of the two training sessions in February, and bring with them a completed Backflow Prevention Device Testing Application along with a copy of the certificate, wallet card, and equipment calibration form(s). 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.
