Test Valves used for system testing must be approved.

Test Valves used for system testing must be approved.

• A. Must be listed
• B. Must be installed underground
• C. Must be remote supervisory capable
• D. Must be approved

Answer: (D)

Test valves used for system testing must be approved to ensure they are suitable for the job and won’t compromise the fire protection system during a test. Approval means the device has been evaluated and accepted for residential sprinkler use, confirming it can handle the service conditions, is compatible with the piping and materials, and won’t introduce leakage, backflow, or other failures when subjected to testing pressures. This requirement is about the general suitability of the valve for use in the system, not about being installed underground or having remote supervisory capability. Listing is related but not the sole path to approval; what matters is that the valve is approved for use in the system.
