I believe the correct answer is NFPA 20 does not allow this, but NFPA 20 only governs the fire pump itself, so anything downstream of the discharge is governed by 13/14/etc and the PRV would be the correct, while maybe not preferable, solution.

The insurance inspector wants the existing pressure reducing valve to be replaced with a pressure relief valve. The pressure reducing valve is downstream of the fire pump and limits pressure on a supply to an older part of the facility. Joe C. Powell Pruett Ford & Associates, Inc.
