Suggestions for Irrigation Backflow Inspections
Federal and State regulations as well as District Policies require that a backflow prevention device be installed where there is the possibility of a cross connection with the public water supply. Each device is required to be tested by law annually to insure that it is working properly. These regulations are for your protection. American Backflow Inspectors would like for every customer to pass their test on the FIRST visit. By taking a few basic precautions, it will greatly increase your opportunity to have a passing result. It is the District’s responsibility to see that each device is tested. It is American Backflow Inspectors responsibility to see that the device is tested properly and it is your responsibility to see that it is READY to be tested. We take our responsibility very seriously.American Backflow Inspectors will begin testing backflow devices beginning May 1st. Prior to our arrival we will issue you a courtesy call to let you know when we will be inspecting in your area. We suggest that you take the following steps to insure that your device is ready:
- Have your irrigation contractor flush the line prior to reinstalling your winterized backflow preventer. This will help eliminate debris in the line that can go into the backflow preventer and cause a failure.
- You can have your irrigation contractor energize the system up to the number 2 shut off valve (see diagram). You do NOT have to start using the irrigation system at this time, but the water MUST be on up to the number 2 shut off valve on the backflow preventer for a test to be conducted.
- Have your irrigation contractor clean and inspect your device and check for obvious problems, such as leaks, cracks, missing parts, etc. Be sure the device meets the minimum height requirement of 12 inches above grade (mulch is considered grade). Have your irrigation contractor check your backflow internal parts thoroughly as part of their Spring start up procedure.
- If your phone number has changed, is unlisted or you would like to leave a different number where you can be reached, please call ABI at 366-8983. We cannot contact you if we do not have a valid phone number.
- Even if you do not plan to use your irrigation system, it MUST either be tested or completely removed. To be considered completely removed, the backflow device must be removed and the piping cut and capped below grade. Please let us know if you have removed your device and we will conduct a survey.
