Troubleshooting a Submersible Water Pump That Isn’t Working


Submersible water pumps are essential tools for draining water from wells, pools, and flooded basements. However, like any mechanical device, they can sometimes fail to operate properly. If you find yourself in a situation where your submersible water pump is not working, there are several potential issues that you can troubleshoot before seeking professional help.


Understanding Your Submersible Water Pump


Submersible pumps are designed to operate underwater, which allows for efficient water removal from various locations. They consist of several parts, including the motor, impeller, and seals. The motor is located at the bottom and is immersed in the water, helping push water to the surface through a discharge pipe. When a submersible pump fails, it usually falls into one of three categories electrical issues, mechanical issues, or clogs.


Common Issues and Solutions


1. Electrical Problems

First and foremost, ensure that the pump is receiving power. Check the power source, such as the circuit breaker, fuses, or power cord. A tripped breaker or blown fuse can easily prevent your pump from starting. If you are using an extension cord, ensure it is rated for use with submersible pumps and is not damaged.


Once you've confirmed power is reaching the pump, inspect the switch. Submersible pumps often have a float switch that detects water levels. If the float is stuck or damaged, the pump may not turn on. Manually lifting the float can test this; if the pump activates, the float needs repair or replacement.


2. Mechanical Issues

If the pump has power but still does not work, the problem may be mechanical. A common issue is the pump motor burning out. If you hear a humming sound when attempting to turn on the pump, it’s possible that the motor is seized or damaged. If this is the case, the motor may need to be replaced, which can be a complicated and costly procedure.


Another mechanical issue could be with the impeller. Impellers can become clogged with debris, which can block water flow. If you suspect this is the case, disconnect the power and carefully remove the pump from the water. Inspect the impeller for signs of blockage and clean any debris that you find. For more serious damage or wear and tear, you may need to purchase a replacement impeller.


3. Clogs and Debris


Debris in the pump or discharge line is another common issue that can prevent operation. Ensure that the discharge line is free of obstructions. You can do this by detaching the line and flushing it out. Additionally, check the intake screen of the pump for clogs. A dirty or blocked intake can prevent water from reaching the impeller, inhibiting the pump’s function.


4. Environmental Factors


Lastly, environmental factors can affect pump operation. If the well or the area around the pump has significantly low water levels, the pump may not be submerged deep enough to operate effectively. Conversely, extremely high water levels can lead to flooding and affect the stability of the pump. Ensure that the conditions are suitable for the pump's operation and adjust its depth or location as needed.


Conclusion


If your submersible water pump is not working, there are various issues that could be at play, ranging from simple electrical problems to more complex mechanical issues. By systematically checking each aspect of your pump and addressing any found problems, you can often restore it to working condition without the need for a professional. However, if you’ve exhausted all troubleshooting methods and the pump still does not function, it may be time to consult with or hire a qualified technician to address the issue comprehensively. Maintaining your pump through regular checks and cleaning will help keep it in good working order and prevent future issues.
