Diesel fire pumps are required to be test ran weekly for how many minutes?

• A. 30
• B. 15
• C. 60
• D. 45

Answer: (A)

Regularly exercising a diesel fire pump is essential to ensure it will start and deliver the required fire flow when needed. For diesel pumps, the weekly test run should last 30 minutes. This length is chosen to thoroughly exercise the engine, governor, lubrication and cooling systems, and the pump itself under load, so you can verify that the pump can maintain the necessary discharge pressure and flow. The test also checks the automatic start function and confirms there are no latent issues like air leaks, fuel contamination, or overheating. Shorter runs might not reveal problems, while longer runs aren’t the standard weekly requirement.
