How often does NFPA 20 require a diesel fire pump to be run?

Explanation:
NFPA 20 requires weekly exercise of the diesel engine–driven fire pump. Running the pump on a regular weekly basis keeps the engine, fuel system, cooling, lubrication, and batteries in good condition so the unit will start and deliver water when needed. It also helps prevent issues like wet stacking and fuel degradation that can occur if a diesel sits unused for long periods. In addition, NFPA 20 calls for a more thorough full-load test at least annually, but the routine weekly run is the standard ongoing readiness check. Options calling for daily, monthly, or quarterly runs don’t align with this continuous-preparedness requirement.
