Routine Fire Pump Inspections and Their Importance
Fire pumps develop wear and tear over time — corrosion, fatigue, and deterioration are normal as time goes by. The worst thing that can happen is to discover your fire pump has an issue in the middle of a fire. That’s why fire pump inspections are essential.
Read on to find out how to conduct routine fire pump inspections.
The Importance of Routine Fire Pump Inspections
Regular inspections make sure your fire pumps operate as they should in the event of a fire outbreak. But that’s not all.
Fire pumps must also comply with the National Fire Protection Association (NFPA) and other regulatory bodies. NFPA 20 fire pump testing, for example, requires that you regularly inspect, test, and maintain your fire pumps in accordance with NFPA 25, which outlines the specific procedures you should conduct so that they’re always in good working condition.
NFPA 25 is a widely recognized standard, and noncompliance can have serious consequences, such as legal action, fines, and even jail time. Most local and state authorities have incorporated this standard into their own building and fire codes.
Additionally, most insurers will require compliance with NFPA 25 before agreeing to insure your business, building, or home. Noncompliance can increase your premiums or even result in a nonpayment if a fire destroys your property.
NFPA 25: Fire Pump Testing Key Components
According to NFPA 25, you should conduct weekly, monthly, and annual inspections on your fire pump systems.
Weekly
NFPA 25 requires you to perform weekly inspections, as well as a no-flow test on your pumps if you have a diesel or engine-powered system. These checks should typically include the following.
Diesel Engine System
Your diesel engine system should meet the following conditions:
- The fuel tank should be at a minimum of two-thirds full.
- The controller selector switch should be in the auto position.
- Two batteries’ charging current readings and voltage readings should be within acceptable ranges.
- Two batteries’ pilot lights should be on, while their failure pilot lights are off.
- The crankcase oil and cooling water levels should be within acceptable ranges.
- The batteries’ electrolyte levels should be within an acceptable range.
- There should be no corrosion on the battery terminals.
- Pilot lights signaling an alarm should be off.
Electric System
For these controls, check that:
- The transfer switch’s normal pilot and controller pilot lights are on.
- The normal phase rotation pilot light is on. Alternatively, the reverse phase alarm pilot light should be off.
- The oil level on the vertically aligned motor sight glass is within an acceptable range.
Pump House and Pump System
You should also make sure the pump’s assembly is free from any physical damage and in good operating condition. To do this, check that:
- The heat in the pump house with engine heaters is not less than 4 degrees Celsius.
- The heat in the pump house without engine heaters is not less than 21 degrees Celsius.
- The ventilating louvers can operate freely.
- The pump suction, bypass valves, and discharge are fully open.
- The floor is free from excess water in the pump house.
- There’s enough water in the suction reservoir of the pump system.
Monthly
Every month, NFPA 25 requires that you conduct a no-flow test of the electric pumps that aren’t listed for inspection on a weekly basis. During this test, you should turn on the pump for at least 10 minutes to observe how it functions without water.
You should check for:
- Delays in the startup time
- Unusual vibrations or noises
- The operation of the pressure relief valves
Annual
Because they can be highly technical, it’s best to let a certified professional or fire protection company perform your annual inspections and tests for you. These involve testing the full system for its ability to deliver the required water pressure and include:
- Determining the pump’s performance at different capacity levels, including 100% and 150% capacity
- Comparing the performance results with the original equipment manufacturer’s specifications
