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 for you.
