Troubleshooting a Submersible Water Pump That Isn't Pumping Water


Submersible water pumps are invaluable devices used in various applications, from draining basements to agricultural irrigation. However, encountering a situation where your submersible water pump is not pumping water can be frustrating. Fortunately, there are several common reasons for this issue, and understanding how to troubleshoot can help you get your pump back in action.


Check the Power Supply


The first step in troubleshooting a submersible pump is to ensure it is receiving power. Check the circuit breaker or fuse box to confirm that the pump is properly connected and powered. If the breaker has tripped or a fuse has blown, reset the breaker or replace the fuse and see if the pump starts functioning again.


Inspect the Pump for Blockages


Another common reason a submersible pump might fail to operate is blockage. Debris, mud, or even sediment can accumulate around the pump intake, restricting water flow. Carefully remove the pump from the water and inspect the intake screen for any obstructions. Cleaning the screen and ensuring it is free of debris can often resolve the issue.


Check the Float Switch

Most submersible pumps are equipped with a float switch that controls the pump's activation based on water levels. If the float switch is stuck in an off position due to debris or mechanical failure, the pump will not activate. Ensure that the float switch moves freely and is not entangled with any hoses or cables. If it appears damaged, it may need to be replaced.


Assess the Impeller and Motor


If the power supply, blockages, and float switch seem to be functioning properly, the problem might lie within the pump’s motor or impeller. A locked impeller or a burned-out motor could prevent the pump from operating. Disconnect the power and carefully inspect the impeller for any signs of damage or obstructions. If the impeller is immobilized, gently clear any debris or replace it if it’s damaged. In the case of a burned-out motor, the pump may require professional repair or replacement.


Evaluate the Depth and Water Source


Finally, consider the water source and depth. If the water level is too low and the pump is no longer submerged, it will not be able to draw water. Ensure that the water level is adequate for the pump to function.


In conclusion, if your submersible water pump is not pumping water, don’t panic. Start by checking the power supply, inspecting for blockages, and examining the float switch. If these steps do not resolve the problem, look deeper into the impeller and motor, and assess your water source. By following these troubleshooting tips, you can restore your pump’s functionality and ensure it performs effectively for all your water pumping needs.
