Approved Backflow Prevention Devices: Fact Sheet



The purpose of this Fact Sheet is to provide a list of approved backflow prevention devices/assemblies for containing potential contamination as required by Section 5-1.31 of the State Sanitary Code.


The New York State Department of Health (DOH), Bureau of Water Supply Protection, will only accept those backflow prevention devices/assemblies which appear on the current edition of the List of Approved Backflow Prevention Assemblies generated by the University of Southern California Foundation for Cross-Connection Control and Hydraulic Research (FCCCHR). Please note that along with double check, double check detector, reduced pressure and reduced pressure detector assemblies, the FCCCHR list includes atmospheric and pressure vacuum breakers which do not satisfy Section 5-1.31 of the State Sanitary Code.

The FCCCHR list is copyrighted and therefore may not be freely distributed by DOH. However, backflow prevention device/assembly manufacturers may be contacted to provide documentation of FCCCHR approval for specific device models, sizes, configurations and shut-off valves. Manufacturer provided documentation (i.e., catalog cut sheets) which indicates FCCCHR approval will satisfy Section 5-1.31 of the State Sanitary Code during the review of plans and specifications for the installation of backflow prevention devices/assemblies.

The following backflow prevention device/assembly manufacturers are currently included in the FCCCHR list and provide FCCCHR approval status on their respective web sites: Ames, Apollo/Conbraco, A.R.I., Cla-Val, Febco, Flomatic, Hersey, Watts and Wilkins.

If the required documentation cannot be obtained via a device/assembly manufacturer, individuals with questions regarding the approval status of a device/assembly can contact their local County Health Department, DOH District Office or the DOH Central Office (518-402-7676).

Devices/assemblies which are out of production, or have only spare parts available, may not appear on the FCCCHR list. If such devices/assemblies are currently installed, they may remain in service provided that they are appropriate for the degree of hazard. When these assemblies demonstrate repeated test failures, require frequent maintenance or if spare parts cannot be readily obtained, they must be replaced by a currently approved device/assembly.
