City of San Diego Public Utilities Department: backflow test rules
- Who must test. All 1.5-inch and larger meters for multi-family and commercial or industrial service, and dedicated irrigation meters of any size, must have a backflow prevention assembly at each meter. Source.
- Notices and deadlines. Courtesy reminders go out 30 days and 15 days before the due date, and a five-day notice of water service termination is mailed on the due date. Source.
- How the report is filed. Approved testers submit and certify test reports in the C3 Tester Portal (Salesforce based); no paper copies are needed after a successful submission. Source.
- Tester registration. Testers certified by AWWA (CA-NV) or ABPA must attend a City Tester Orientation (held January and July) and provide current gauge calibration and tester certification copies. Source.
- Fees. There is no fee to be on the City's tester list; anyone with AWWA or ABPA certification can apply. Source.
