A Professional Engineer (PE) or Registered Architect (RA) must prepare and submit two sets of plans and two applications originals (form GEN-236 New York City Version) for the installation of Backflow Prevention Device(s) to the Bureau of Water and Sewer Operations, Division of Permitting and Inspections for approval. All submissions must have original ink signatures and original ink or impression seals. Plans and applications must be corrected and resubmitted as necessary until acceptable.
When the plans are approved, the Division of Permitting and Inspections issues a plan approval letter to the customer and returns one copy of the approved plans to the PE or RA of record.
The device(s) must be:
- Installed by a New York City Licensed Master Plumber in accordance with the approved plans (installations must also meet the Building Department’s and the Bureau of Customer Service’s requirements).
- Tested by a State Certified Backflow Prevention Device Tester who is either a Licensed Master Plumber or employed by one.
- Inspected by a PE or RA and certified that they have found the installation to be in accordance with the approved plans.
Finally, a completed “Report on Test and Maintenance of Backflow Prevention Device” (form GEN-215B), certifying the job, must be submitted to DEP within thirty days of installation of the device.
Annual Inspection: At least once a year, the device must be inspected, maintained and tested, by a state certified tester. The results of the test must be reported to the department by filing Form GEN 215B with parts A & B properly completed
