Troubleshooting Submersible Pump Not Lifting Water


Submersible pumps are essential devices used in a variety of applications, such as draining water from flooded areas, providing water supply for irrigation, and supporting residential water systems. However, there can be scenarios where a submersible pump fails to lift water, leading to inconvenience and potential damage. Understanding the common issues associated with this problem can help you troubleshoot effectively and restore functionality.


Common Causes of Failure


1. Power Supply Issues The first step in troubleshooting a submersible pump is to check the power supply. Ensure that the pump is properly connected to a power source and that the circuit breaker hasn’t tripped. A faulty power cord or an issue with the outlet can also prevent the pump from operating.


2. Clogs and Obstructions Over time, debris can accumulate in the pump, clogging the inlet screen or impeller. If a pump is submerged in a murky water source, particles such as leaves, mud, and stones can obstruct the flow of water. Regular maintenance to clean the intake and ensure that the pump is free of obstructions can help prevent this issue.


3. Pump Damage Physical damage to the pump itself is another common reason for failure. This could be due to wear and tear, corrosion, or manufacturing defects. Inspect the pump for any visible damage, such as cracks in the casing or wear on the impeller. If internal components are damaged, it may require repair or replacement.


4. Incorrect Depth Installation The installation depth of a submersible pump is crucial for optimal performance. If the pump is installed too deep, it might not have adequate pressure to displace water. Conversely, if it is situated too close to the surface, it may be drawing air instead of water. Always ensure that the installation depth is within the manufacturer’s specified range.

5. Air Lock In certain situations, an air lock can occur within the pump or the piping system. This happens when air enters the system and prevents water from flowing. To resolve this, check the discharge hose for kinks or bends and ensure that it is properly positioned. Bleeding the system to release trapped air can also help restore functionality.


6. Electrical Issues Faulty electrical components, such as the pressure switch or capacitors, can affect the pump’s performance. A malfunctioning pressure switch may fail to trigger the pump to operate, while electrical shorts can cause the pump to stop working altogether. A qualified technician should assess and repair these electrical components to ensure safe operation.


Preventive Measures


Preventing future issues before they arise can save time and money. Regular maintenance is key. This includes routine inspections, cleaning the pump and associated plumbing, and ensuring that the pump is properly lubricated as per the manufacturer’s guidelines. Additionally, investing in a surge protector can safeguard your pump against power surges that could lead to electrical failure.


Conclusion


A submersible pump that won’t lift water can be frustrating, but understanding the possible causes allows for effective troubleshooting. By methodically checking each aspect of the power supply, the pump’s integrity, and the surrounding environment, you can identify the problem and address it swiftly. Regular maintenance and vigilance can further ensure that your submersible pump continues to perform at its best, providing reliable service for years to come. Should problems persist despite troubleshooting, consulting a professional may be necessary to prevent further damage and ensure the longevity of your pump.
