Backflow Testing

Testing of Backflow Prevention Devices (RPZ and DCV devices only) and Filing

Testing of the backflow prevention device must be performed by a state certified tester upon installation, and annually testing must be conducted thereafter.

Each year a certified tester must test the device and file the results with the South Farmingdale Water District and the Nassau County Department of Health.  The form used must be completed in its entirety, otherwise it will be rejected.
