How should backflow prevention devices be integrated within NFPA 13E guidelines?

• A. Not required for any system.
• B. Installed only on the main supply.
• C. In accordance with code requirements to protect the public water supply while ensuring proper operation of the protected system.
• D. Only necessary for residential systems.

Answer: (C)

Backflow prevention devices are required whenever a fire protection system is connected to a public potable water supply to prevent contamination of drinking water. NFPA 13E guidance emphasizes protecting the public water supply by installing the appropriate backflow prevention device in accordance with code requirements and the water utility’s rules, while still ensuring the protected system can operate reliably. In practice, this means placing the device on the supply line to the fire protection system before any cross-connection to non-potable sources, selecting the appropriate type based on the risk and local requirements, and maintaining/testing the device on the prescribed schedule. This approach aligns with the goal of NFPA 13E to safeguard public health without compromising the effectiveness of the sprinkler or standpipe system. The other options fall short because they either imply no protection, restrict installation to the main only in all cases, or limit protection to residential systems, which is not accurate for typical fire protection applications.
