Testing of Backflow Prevention Devices

In all cases, irrigation systems require an approved backflow prevention device 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 protecting the water supply. Failure to comply can result in fines and shut off of service.
