Pool Pump Problems? Try These Time-saving Hacks

Pool pump problems can be frustrating and time-consuming to deal with. A malfunctioning pool pump can disrupt your swimming routine and lead to costly repairs if not addressed promptly. Fortunately, there are several time-saving hacks that can help you troubleshoot and resolve common pool pump issues. In this comprehensive guide, we will explore five common pool pump problems and provide you with practical solutions to save you time and effort. Whether you are a pool owner or a professional pool technician, these hacks will help you keep your pool pump running smoothly.

1. Low Flow Rate

One of the most common pool pump problems is a low flow rate. If you notice that the water flow in your pool is weak or inadequate, there are several potential causes to consider:

  • Clogged Skimmer Basket: A clogged skimmer basket can restrict water flow into the pump. Check the skimmer basket and remove any debris or leaves that may be blocking it.
  • Blocked Impeller: The impeller is responsible for drawing water into the pump. If it becomes blocked or clogged, it can reduce the flow rate. To check the impeller, turn off the pump and remove the pump lid. Inspect the impeller for any debris or obstructions and clean it if necessary.
  • Dirty Filter: A dirty or clogged filter can also restrict water flow. Check the filter and clean or replace it if needed.
  • Leaking Suction Line: A leaking suction line can introduce air into the system, causing a decrease in flow rate. Inspect the suction line for any leaks and repair them if necessary.

By addressing these potential causes, you can improve the flow rate of your pool pump and ensure proper circulation of water.

2. Noisy Operation

If your pool pump is making unusual noises, such as grinding, squealing, or rattling sounds, it may indicate a problem that needs attention. Here are some common causes of noisy pool pump operation:

  • Loose Motor Mounting: A loose motor mounting can cause vibrations and noise. Check the motor mounting bolts and tighten them if necessary.
  • Worn Bearings: Over time, the bearings in the motor can wear out, leading to noise. If you suspect worn bearings, it is best to consult a professional technician to replace them.
  • Debris in the Pump: Debris, such as rocks or leaves, can get stuck in the pump and cause noise. Turn off the pump and inspect the pump housing for any debris. Remove any obstructions carefully.
  • Impeller Issues: A damaged or misaligned impeller can also cause noise. Inspect the impeller for any signs of damage or misalignment and replace or realign it if necessary.

By identifying and addressing the source of the noise, you can restore quiet operation to your pool pump.

3. Pump Not Priming

If your pool pump is not priming properly, it may struggle to draw water and operate efficiently. Here are some steps you can take to troubleshoot and resolve this issue:

  • Check the Water Level: Ensure that the water level in the pool is sufficient for the pump to prime. If the water level is too low, add water until it reaches the appropriate level.
  • Inspect the Pump Lid O-ring: The pump lid O-ring creates a seal that prevents air from entering the system. If the O-ring is damaged or worn, it can cause priming issues. Inspect the O-ring and replace it if necessary.
  • Check the Valves: Ensure that all valves in the system are in the correct position. If a valve is partially closed, it can impede the priming process. Open any closed valves to allow proper water flow.
  • Prime the Pump Manually: If the above steps do not resolve the issue, you can try priming the pump manually. Consult your pump’s manual for specific instructions on how to prime it manually.

By following these steps, you can improve the priming process and ensure that your pool pump operates efficiently.

4. Pump Motor Not Starting

If your pool pump motor fails to start, it can be a frustrating problem to deal with. Here are some potential causes and solutions:

  • Check the Power Supply: Ensure that the pump is receiving power. Check the circuit breaker or fuse box to make sure the pump’s circuit is not tripped or the fuse is not blown.
  • Inspect the Motor Capacitor: The motor capacitor provides the initial boost of power to start the motor. If the capacitor is faulty or worn out, it can prevent the motor from starting. Consult a professional technician to test and replace the capacitor if needed.
  • Examine the Motor Switch: The motor switch controls the on/off operation of the pump. If the switch is faulty, it may prevent the motor from starting. Consult a professional technician to test and replace the motor switch if necessary.
  • Check for Motor Overheating: If the motor overheats, it may have a built-in safety feature that prevents it from starting until it cools down. Allow the motor to cool and check for any signs of overheating, such as a burning smell or hot motor casing.

By addressing these potential causes, you can troubleshoot and resolve the issue of a non-starting pump motor.

5. Pump Leaking Water

A pool pump that is leaking water can lead to water loss and potential damage to the pump and surrounding equipment. Here are some common causes of pump leaks and their solutions:

  • Inspect the Pump Lid O-ring: A damaged or worn pump lid O-ring can cause water to leak from the pump. Inspect the O-ring and replace it if necessary.
  • Check the Shaft Seal: The shaft seal prevents water from leaking out of the pump motor. If the seal is worn or damaged, it can cause leaks. Consult a professional technician to replace the shaft seal.
  • Examine the Pump Housing: Inspect the pump housing for any cracks or damage that may be causing leaks. If you notice any issues, consult a professional technician for repair or replacement.
  • Inspect the Plumbing Connections: Check all plumbing connections around the pump for any signs of leaks. Tighten any loose connections or replace faulty seals.

By addressing these potential causes, you can prevent water leaks and ensure the proper functioning of your pool pump.


Dealing with pool pump problems can be time-consuming, but with the right knowledge and troubleshooting techniques, you can save time and effort. In this guide, we have explored five common pool pump problems and provided practical solutions to resolve them. By addressing low flow rates, noisy operation, pump priming issues, non-starting pump motors, and water leaks, you can keep your pool pump running smoothly and enjoy a clean and well-circulated pool. Remember to consult a professional technician if you are unsure or uncomfortable with any troubleshooting steps. Regular maintenance and prompt repairs will help extend the lifespan of your pool pump and ensure optimal performance.
