BACKFLOW PREVENTION FAQs

Certified Backflow Tester #10500

Why are backflow prevention devices required?

Backflow prevention devices are an important component of our drinking water protection program and are legally mandated under the New York State Sanitary Code and the Rules of the City of New York for those businesses identified as posing a risk to the public water supply.

What types of properties must install backflow prevention devices?

In general, all buildings in New York that fit into any of the following categories are required to have a backflow prevention device:

 

  • Properties with (2) or more residential dwellings, including (but not limited to) detached homes, brownstones, and apartment buildings.

  • Mixed-use properties that include at least (1) commercial space and (1) residential dwelling.

  • Properties with in-ground irrigation (ex: lawn sprinklers).

  • Most commercial use buildings, especially those that contain restaurants, food processing plants, schools, sewage treatment plants, warehouses with toxic storage, and hospitals, to name a few.

For a full list of property types required to have backflow prevention devices, please visit the FAQ of the New York City Department of Environmental Protection here.

Who is responsible for installing a backflow prevention device?

Property owners must hire a Licensed Master Plumber to install a backflow prevention device. Tenants are not responsible for managing the installation or maintenance of backflow prevention devices.

Recently, I received an order to install a backflow prevention device. The 30-day installation period has nearly expired. How can I avoid a Notice of Violation?

As long as the DEP has certification in writing from a Licensed Master Plumber that a device is in the process of being installed, you will not receive a Notice of Violation.

Can A Plus Plumbing Corp. install, inspect, and clear or help to prevent violations related to backflow prevention devices?

Yes, yes, and yes!
