How Long Do Pool Pumps Last

How Long Does A Pool Pump Last?

Pool experts say pumps should last between 8-12 years, on average. However, there are a few factors that can either increase or decrease the pump’s lifespan.

What Impacts A Pool Pump’s Life Expectancy?

Let’s take a look at three factors influencing how long your pool pump will last.


How much and how often you run your pump will undoubtedly have a direct impact on the pump’s life. Your pump experiences more wear and tear when you use it often. The type of pump can also impact the overall lifespan.

The majority of pool owners will use one of two types of pumps, including single and variable speed. Single speed pumps are less expensive, yet running at just one speed can be a design flaw. Variable speeds, meanwhile, can offer a range of speeds. This is ideal for certain situations like cleaning a green pool or running the filter throughout the night. Varaiable speed pumps are more energy-efficient than the alternative.

Pump Size

An undersized pump will overwork itself when the pool area is larger. Oftentimes, a smaller pump will need to run longer than normal in order to compensate for the area. Overuse will dramatically reduce the lifespan of the pump. Small to average-sized pools call for a 1.5 hp pump or more.


Small elements of the pump, including O-rings, screws, and sealants can wear out over time. The faster you take care of any maintenance needs, the better. Inspect your pump a few times per year for worn down sealants, missing screws, housing cracks, and broken O-rings.

How To Tell If Pool Pump Is Going Bad

A total of two elements are present in pool pumps: the pump and motor devices. Either device could end up going bad over time. Here are a few key signs that indicate it may be time for a replacement:

  • Complete motor failure.
  • The pump is not pumping water.
  • The pump is leaking.
  • Motor is making loud noises.

How To Replace A Pool Pump

If you are planning on replacing a pool pump yourself instead of hiring a professional service, then follow these steps:

Turn Off The Power

The first thing you’ll need to do when replacing a pump is to disconnect the power source to the pump. The safest way to do this is by switching the appropriate circuit breaker to the “off” position. After the power is switched off, test the pool pump to make certain the power is off.

Disconnect And Remove Pump

After turning the power off, remove the cover of the motor and disconnect all electrical wiring to the pump. Then disconnect any and all plumbing connections to the old pump. An adjustable wrench can be used to make the process easier and more efficient. Be careful, trying not to damage these connections because they are the same parts you will use for the new pool pump. Remove the old pump entirely once you have completely disconnected the old pump.

Connect New Pump

Connect the electrical wires to the new pump after removing the cover of the motor. Once all plumbing and electrical components are connected, you can turn the new pump on and start priming it.

Turn Power On

First, make sure the power switch on the pump is in the “off” position. Then you can turn the appropriate circuit breaker to the “on”position.

Prime The New Pump

The last part of the replacement process is priming the new pump. Fill the pump up with water, making sure the pump trap fills completely. Carefully monitor the water, ensuring that it moves through the suction lines of the pump once the pump is turned on. Next, open the inlet shutoff valves until the water circulates all throughout the pump. Now your new pump is ready for use!

How Much Does A Pool Pump Replacement Cost?

The average cost for a pool pump replacement is $440, with prices ranging all the way from $80 to $800. These average costs do include the price of labor, as well.

Pool ownership will always require general maintenance throughout the year, including repairs to the pool liner and heater. Of course, occasionally you may have to replace the pump, as well. The pump is a vital component of the pool’s filtration system, making a replacement necessary when the time comes. When hiring a professional to replace the pump, one can expect to pay between $80-$200 for manual labor.
