Fire pump diversion time and how to polish the fire pump

It seems there might be a confusion in the terms used. "Fire pump diversion time" is not a commonly known term in the context of fire pumps. However, "fire pump churn time" might be a more relevant term.

1. Fire Pump Churn Time: The churn time of a fire pump refers to the time it takes to test the pump's readiness and functionality without flowing water. During this test, the pump remains connected to the water supply, but water is not discharged. Churning the pump periodically is essential to ensure it is in proper working condition and ready to function when needed.

2. Fire Pump Polishing: The term "polishing" is not commonly associated with fire pumps. However, it's possible that you might be referring to "flushing" or "exercising" the fire pump.

   • Flushing: Flushing the fire pump involves running water through the pump to remove any accumulated debris, rust, or sediment. This helps to prevent clogging and ensures that the pump's internal components remain clean and functional.

   • Exercising: Exercising the fire pump means running the pump regularly (often at least weekly or monthly) to ensure it remains operational and prevent components from seizing due to prolonged inactivity. Regular exercising helps maintain pump efficiency and can identify potential issues before they become critical.

Fire pump maintenance and testing procedures are essential to ensure the reliability and effectiveness of the fire protection system. Proper maintenance, including regular inspections, churning, flushing (if necessary), and exercising, should be performed according to the manufacturer's guidelines and relevant fire safety standards. It's crucial to involve qualified personnel or fire protection experts to carry out these activities to ensure the fire pump is always ready for emergency situations.
