When fire season approaches, your fire pump becomes one of the most important tools on your property. Regular maintenance is key to ensuring it operates reliably when you need it most. Whether you use your pump for bushfire protection, general water transfer, or agricultural use, proper care can extend its lifespan and improve performance.
Crommelins fire pumps are built for dependable service, but like any piece of machinery, they need routine attention to stay in top condition. Below, we’ve summarised key maintenance practices based on the Crommelins Fire Pump Operation Manuals. These steps are useful for all pump owners but always refer to your specific manufacturer’s manual for exact procedures.
Perform Pre-Operation Inspections
Before each use, take a few minutes to check over your fire pump. According to Crommelins’ guidelines, you should always inspect the engine oil level, fuel supply, and air filter before starting the engine.
Make sure the engine switch is in the ON position, the spark plug is clean and connected, and the pump is on a level surface. These quick checks help prevent startup issues and ensure smooth operation during an emergency.
Proper Priming and Water Source Management
Improper priming is one of the most common causes of pump failure. Both the single and twin impeller manuals emphasise that before starting, you must fill the pump and ensure suction pipe is submersed in water.
Ensure all pipe joints are airtight, as even small air leaks can stop the pump from priming. Never run the pump dry, as this can destroy the mechanical seal and void the warranty.
If you’re drawing water from a dam, tank, or pool, use a suction strainer to prevent gravel, leaves, or debris from entering and damaging the impeller.
Optimal Operating Practices
Running your fire pump at the right speed extends its life. The Crommelins manuals recommend operating at around 3000rpm for general use. Reserve higher speeds for active firefighting or when you need maximum pressure.
Avoid obstructions or leaks in suction lines, and keep the suction lift within 8 metres for effective priming. Before each use, check that the non-return valve moves freely to prevent air lock or backflow.
Routine Cleaning and Seasonal Servicing
After each use, clean any oil and dust accumulation on rubber and metal parts to prevent wear and corrosion. Remove any dirt or debris from around the engine and casing.
To keep your pump performing year after year, schedule an annual service with an authorised Crommelins service agent. Find your nearest agent for professional maintenance and support.
Storage Tips for the Off-Season
When fire season ends, proper storage will protect your investment:
- Allow the engine to cool completely before storing.
- Drain all water from the pump to prevent corrosion or freeze damage.
- Empty the fuel tank and carburettor chamber if storing for an extended period.
- Store in a dry, covered area to protect against dust, moisture, and UV damage.
Following these steps ensures your pump will be ready to perform at full capacity when needed again.
Troubleshooting Basics
Even with good maintenance, issues can arise. Here are some quick checks:
- Engine won’t start: Ensure the switch is ON, there’s fuel in the tank, and the spark plug is clean.
- Pump won’t prime: Look for air leaks or blockages, and make sure the water level isn’t more than 8 metres below the pump.
- Engine running rough: Clean or replace the air filter and refill with fresh fuel.
