How To Replace A Pool Pump

Pool experts say pumps should be replaced every 8-12 years, on average. When it comes time to replace the pump as your next DIY project, use this article as your how-to guide.

Replacing A Pool Pump In 5 Steps

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

1. 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.

2. 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.

3. 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.

4. 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.

5. 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.

How To Tell If Pool Pump Is Going Bad

• Complete motor failure.
