Backflow is unwanted flow of water in the reverse direction. It can be a serious health risk causing contamination of drinking water supplies with foul water.  Annual backflow testing, installation and service is provided by our Plumbing division.

Steps for Device Installation and Inspection Procedure from the New York City Environmental Protection Agency website are as follows:

To install, operate and maintain a proper backflow prevention device, follow the steps below as advised by the EPA:

  1. First, you must hire a Professional Engineer (PE) or Registered Architect (RA) to prepare two sets of backflow prevention plans for your property. These must be submitted with two application forms to DEP’s Cross Connection Control Unit for approval. If approved, DEP will notify you via mail and return a copy of the plans to your PE or RA.
  2. The backflow prevention device must then be installed in accordance with the DEP-approved plans. Installation must comply with NYC Department of Buildings regulations and requirements.
  3. Once installed, the device must be tested by a New York State Certified Backflow Prevention Device Tester.
  4. Once testing is completed, a test report must be filed immediately with DEP (within 30 days of device installation). In the event of an improper installation, DEP will notify you or your PE/RA. The device will need to be fixed and then resubmitted for inspection and certification.
  5. Your backflow prevention device must be properly maintained, and will be subject to annual testing and inspection by a certified tester.
