Testing of Backflow Prevention Devices
In the case of a residential or commercial irrigation
system, a reduced pressure principle backflow preventer (RP device or
RPZ) is required between the potable water supply and the irrigation system.
These devices are not only required by law, but also due to the requirements
of the backflow prevention program the devices are required to be tested
annually by a certified backflow prevention tester. The annual test is
to ensure that the device is working properly and is a requirement of
the areas' cross connection control program.
Most licensed plumbing contractors have one or more
certified testers in their employ and will be happy to provide this service
