A fire pump boosts water pressure so sprinklers and standpipes work on upper floors, in large warehouses, and at industrial sites. If it doesn't start when needed, the sprinkler system above it may not control a fire.
NFPA 25 requires a no-flow (churn) test weekly for diesel pumps and monthly for most electric pumps. The pump runs without discharging water while the operator checks pressures, packing, temperature, and controller operation.
Once a year, a full flow test measures the pump's output at churn, rated, and peak flow, and compares it to the manufacturer's curve. This is how you find worn impellers, failing drivers, and controller problems before a real fire does.
Skipping tests has real consequences: insurance carriers can deny or limit claims for impaired systems, the fire marshal can cite the property, and diesel pumps that sit idle develop fuel and battery problems that leave them unable to start.
Lake Charles' petrochemical corridor, plus warehouses and high-rises across Louisiana, depend on fire pumps. InspectBlaze performs annual flow tests, documents the results, and can set up the weekly and monthly test logs your staff needs.
