While doing a sprinkler inspection it was found that the main check valve for the system failed. The system was installed before backflows were mandated on sprinkler systems.
I know that a backflow preventer needs to be installed in its place, but have been unable to find any code that says it does.
Anyone able to help?

This will be part of the plumbing or heath code not from NFPA 13. Check your state or local building code for backflow prevention requirements.

As Anthony noted it will be in the plumbing code or health code you may also want to check to see if the municipality has a backflow prevention program, they might be able to force them to install one/repair.

agreee 100% with Anthony. AWWA and UPC requires these, not the fire code. Is your sprinkler connected to Potable water system (public drinking water)- than yes a BFD is required. if connected to a private fire main -and not cross conencted to the city or campus water mains - than not required.

Here in Metro NY backflow devices are initiated by the local Water District for their review and then forwarded if required, to the County Health Department.

This is part of the plumbing code. You won't find it in 13.

The system was installed with a check valve and assumed approved with that installation, its failure during a 25 inspection means repair or replace like for like not add a backflow and potentially change the hydraulics of the system.

NFPA 1 (2018) contains the following:

The type of system wasn't stated. If this is a dry system then only the single check in addition to the dry riser should be needed. Also is there a fire service main with a pit where the backflow device could already be located?

Agree that plumbing codes and water suppliers are where you will find the requirements. But think they are trying to conform to the EPA Safe Water Drinking Act of 1974 but as I recall fire sprinkler systems came into play with the 1986 amendments.
