BACKFLOW PREVENTION DEVICES

The Cross-Connection and Water Pollution Control Program administers the annual testing of approximately 50,000 backflow prevention devices by nearly 700 backflow prevention device testers certified by this program. This extensive record keeping system on backflow prevention device testing, reporting, and data retrieval is monitored by an intricate data processing program.

The hardware approved and employed in the protection of the potable water supply from backflow of contaminants is based upon specifications developed in concert with regulatory agencies, plumbing officials and the manufacturing industry. The laboratory and field approval process of the Foundation for Cross-Connection Control and Hydraulic Research at the University of Southern California and the Mechanical Testing Laboratory of the City of Los Angeles, Department of Building and Safety are essential in developing a reliable listing of approved backflow preventers. Since all mechanical devices are subject to failure, the on-going program for the certification and recertification of backflow prevention device testers and a program of electronic data processing of backflow prevention device test reporting are critical in maintaining the integrity of these devices.

A listing of approved backflow preventers, both testable and non-testable is maintained to provide the public with the most reliable hardware available.
