What Should You Do When Your Pond Pump Impeller Stops Spinning?

August 14, 2020

Pond owners truly know the importance of pond pumps. These pond pumps promote the movement and circulation of water in the pond, preventing it from getting stagnant. These pumps can also introduce more oxygen into the water, sustaining the oxygen supply needed by all the living things underwater.

One specific component of pond pumps that help increase the water flow is the pond pump impeller. Pond pump impeller typically spins and helps move and draw water into it. Without a fully functional impeller, the water movement will stop, cutting off a huge amount of oxygen supply that would lead to the loss of aquatic plants and animals. The liveliness of the pond will also deteriorate significantly since its movement will become inactive.

Causes of Faulty Pond Pump Impeller

All the components of a pond pump require frequent repairs and maintenance since they are being used regularly. Sporadic assessment and maintenance of the components will certainly result in the decline of their performance and functionality. Pond pump impellers, at this point, will not be spared from getting damages and issues.

Pond pump impellers that have become faulty would suddenly stop spinning. One of the most common causes of this phenomenon is due to debris blockages and obstructions. Weeds, waste products, stones, and other materials may have prevented them from functioning. And as the obstructions continue, the motor of the pump will just run even though the impellers do not spin anymore. This situation will ultimately result in the overheating of the pump, which can be difficult to repair.

Another reason why pond pump impeller becomes faulty is due to the problem with either other pump components or the pond’s power supply. The impeller would not spin if the pump does not power on. If the pump trips the ground fault of an outlet, then the problem would lie on the pump itself. On the contrary, a pump that does not respond with the pond’s power supply but responds to others means that the power supply at the pond is faulty.

Solving Pond Pump Impeller Issues

The very first thing that you must do when checking your pond pump impeller is to look for any damages or cracks on its barrel. If there are no visible damages, then you must hold the barrel of the impeller between your fingers and rotate its fins. The rotation of the fins, or lack of it, will determine the current condition of your impeller. The fins must be able to rotate for at least a half turn before they get locked into place. The position on which the fins get locked will depend on their manufacturer.

Alternatively, if the fins of the impeller rotate without stopping, then they might need to be replaced right away. Fins that do not stop typically indicate that they have worn out already. Switching on and off the pumps regularly may have caused the damages received by the fins.

Another thing that you can do to resolve the pond pump impeller issue is to clean out everything around it. Large pieces of rocks and other types of debris can hamper the ability of the impeller to spin. Once you have cleaned it, you must now try to plug it in and see if it will spin. If the impeller is spinning but does not reach the recommended water flow, then you may want to check other pump components and your plumbing system. If the impeller does not spin, then your power supply must be checked.

Ultimately, if the impeller spins optimally, then you must reinstall it to the whole pump system and give it another try. Once everything is running smoothly, then you can install it again at your pond.
