Annual Backflow Testing in NYC: When It's Due and How to Prepare

For NYC properties with covered backflow prevention devices, testing is not a one-time responsibility.

After installation and initial testing, NYC DEP requires these devices to be tested every 12 months.

Property owners may receive a DEP notification when an annual test is due, but maintaining an organized compliance schedule remains important.

For buildings with multiple devices, keeping accurate records of each assembly can help avoid confusion.

A practical backflow compliance record should include the device location, identifying information, previous testing documentation, and upcoming testing dates.

Properties with multiple mechanical rooms, commercial tenants, or complex water systems may require additional coordination to ensure the correct device is tested.

Accessible records also make it easier to respond to DEP correspondence or questions from a new property manager.

Before scheduling, confirm which assembly needs testing and whether the testing location is accessible.

Make sure the appropriate building personnel know when access will be required.

If the device is in a restricted mechanical room or tenant-controlled area, coordinate access in advance.

A clear understanding of the device's location and previous testing history can make the process more efficient.

Annual testing must be performed by a New York State certified tester.

The appropriate annual test report must be completed and signed according to DEP requirements, including the required Licensed Master Plumber signature.

Property owners should ensure that the required documentation is submitted through an accepted DEP process.

Keep copies for your records.

Waiting until a deadline is close can make scheduling and documentation more difficult.

An organized annual testing process gives property owners time to address access issues, questions about device information, or unexpected test results.

If a device does not pass, additional steps may be necessary before compliance can be completed.
