What documentation is required when a fire pump system is modified or repaired under NFPA 20?

• A. Updated drawings, revised hydraulic calculations if needed, test data, and verification that the installation still complies with NFPA 20.
• B. Only the dates of work.
• C. Only a warranty form.
• D. No documentation is required.

Answer: (A)

Documentation when a fire pump system is modified or repaired is required to confirm continued performance and compliance. Updating the drawings ensures the as-built configuration is accurately reflected. If the modification changes how the system delivers water, revised hydraulic calculations are needed to prove the pump can still meet the required head and flow under design conditions. Post-modification test data demonstrates the actual performance of the pump and system after the change. Finally, a verification that the installation still complies with NFPA 20, typically reviewed and approved by the authority having jurisdiction, confirms that all applicable requirements are still satisfied. This documentation creates a traceable record for future maintenance and inspections, ensuring the system remains reliable in an emergency. Dates of work alone don’t prove that the system’s performance or compliance has been maintained, a warranty form doesn’t address operational adequacy, and no documentation at all would leave the installation unverified and non-compliant.
