BACKFLOW PREVENTION DEVICES |
 |
Nearly 700 backflow prevention device testers who
have been certified by the Cross Connection and Water
Pollution Control Program, administer the annual testing
of over 51,000 backflow prevention devices. This program
reviews all test and monitoring results while
maintaining an extensive data base of all devices.
The approved hardware utilized in the protection of
the potable water supply through backflow prevention is
based upon specifications developed jointly 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 prevention
devices. Since all mechanical devices are subject to
failure, the on-going program for the certification and
re-certification of the device testers, as well as the
data base of backflow prevention device test results are
critical in maintaining the integrity of these devices.
A listing of currently approved backflow prevention
devices, both testable and non-testable is maintained to
provide the public with the most reliable hardware
available.
