Release time:2021.11.09

As the heart equipment of the pool filtration system, a healthy pool pump keeps the pool water flowing and stays the pool clean and safe. However, if there’s any problem on your pool pump, your pool will have to shut down. Here are some common pool pump problems and useful simply ways to fix them. Keep reading for the pool pump troubleshooting skills below.

  • Pool pump not turning on

If your pool pump is not able to turn on or quickly shuts off after it’s started, there is usually an electrical problem. It is commonly seen as loose connections, a bad capacitor or overloaded voltage, here is some simple ways for quick fixes:

  * Pool pump repair tips:

    a) Check the breaker box for blown fuses.

    b) Check the electrical connections and make sure nothing is loose, especially on the frayed or broken power cords.

    c) Check the power and the timer to make sure your pool pump is on.

    d) Make sure the pool pump gets the proper voltage with the right wire size.

  • Pool pump not working

If your pool pump does turn on but loses power, there could simply a jammed motor or the pool pump is overheating.

  * Pool Pump repair tips:

    a) Check the motor to see if it’s jammed with debris.

    b) Check the motor’s vents to make sure nothing is blocking the fan.

    c) Run the pool pump during the night to avoid overheating, or simply replace your old pump with an inverter pool pump that can automatically run at 30-100% capacity.

    d) Check your capacitor, which starts the pump by giving it a jolt of electricity, but it is best done by a professional since it can still store power.

    e) If the motor is totally shut down, you may need to replace the motor or the pool pump. The permanent magnet synchronous motor that applied in the inverter pool pump has longer durability and higher efficiency, which should be your first consideration.

  • Pool pump leaking

If your pool pump is leaking water, in most cases it is caused by a pressure-side leak. There could be a damaged o-ring in the impeller housing, bad shaft seal, or a bad thread sealant.

  * Pool Pump repair tips:

    a) Check the o-ring, the rubber ring that forms a seal where the pipes are connected, in the pool pump housing.

    b) Bend the o-ring all around and check if there’s cracks, if no cracks are found, you can use the o-ring lube to help create a better seal and keep the o-ring lasting longer.

    c) Replace the worn o-rings and seals.

  • Pool pump runs with low waterflow

If the flow rate of your pool pump has dropped low, there could be something blocking the water flow in the pool pump or the filter. For example, the filter or pool pump basket could be clogged, or there is too much air in the system.

  * Pool Pump repair tips:

    a) Clean the filter and pool pump basket and impeller.

    b) Check the water level of your swimming pool and make sure it isn’t low.  

    c) Fill your strainer basket with water and reseal it.

    d) Replace your leaky o-ring.

    e) You’ll probably need to prime the pool pump with improved hydraulic system in volute structure design by inverter pool pump InverPro.

  •  Pool pump sucking in air

If your pool pump is sucking in air, it is usually caused by a bad thread sealant, crack in the pump, an air leak in the suction line, a plumbing issue on the suction side of the pump, or a leaky valve stem.

  * Pool Pump repair tips:

    a) Test the leaky place with shaving cream.

    b) Check the pump lid.

    c) Replace the defective part.

    d) Call a professional or a local pool supply store to check.

  • Pool pump humming or making noise

If your pool pump is making loud noise, the reason could be caused by a bad motor in high-pitched screeching sound, or the cavitation in a vibrating sound.  

  * Pool Pump repair tips:

    For cavitation, you can

    a)    Check the pool water level or see if there’s any clog in the plumbing line

    b)    Check if there’s an air leak in the system.

    c)     Learn more from How to Quiet Your Noisy Pool Pump

Maybe it’s time to get it replaced with an inverter pool pump that operates at 36 dBA certified by TUV Rheinland, which is 30 times silent than an on/off pool pump.
