One major component, the pool pump, is called the “heart” of your swimming pool. When this component is acting up, it can put a grinding stop to your summer fun. But how do you know if it’s time to replace your pool pump?

How long does a pool pump last?

Your pool pump should be replaced anywhere between 8 to 15 years depending on the quality, and a full replacement may cost over $800.

Your pool pump is the “heart” of your swimming pool as it circulates water throughout, bringing water through the filtration and heating systems. It’s made up of a motor, impeller, and a hair and lint trap with a basket.

Often when there’s a problem, you can simply replace one of the mechanisms, such as the motor, without replacing your whole pool pump. Select’s qualified technicians would help you through this process.

Common pool pump problems and solutions.

When there’s a problem with your pool pump, you’ll notice many immediate issues. Once your pool pump is down for a few days, you’ll quickly notice algae scum building up.

Take care of these problems right away before your pool requires serious maintenance to re-open.

1. Your filter shows a high pressure on the gauge.

Your pool pump could be clogged, or it’s not strong enough to fit the requirements of your pool.

Be sure to check the impeller, which circulates water, for debris. Anything caught in the impeller will prevent water from pulling through. Be sure to also change the hair and lint trap in case it’s overloaded and causing debris to pull into the impeller. The basket should be changed at least once every two weeks.

2. The pool pump is overheating.

This problem could be occurring for a few reasons and might even result in a fire, so be very careful when handling the machine. Many swimming pools are located in direct sun, so it’s normal for your pool pump to become very hot – but not so hot that you cannot touch it.

When your pool pump is clogged for an extended period of time, it begins to pull air instead of water, causing the impeller to spin rapidly. This problem is called “loss of prime” and causes the motor to burn out. You’ll need to discuss the damage with a technician to see if the whole motor must be replaced.

On the inside of your pump, there could be excessive friction due to the motor’s bearings wearing down, and this might even lead to a leak in the pump. Parts must be replaced within the motor before it’s too late.

You may also want to look into what’s called a “variable speed” pump. This type of pump helps reduce the cost of electricity and lessens the load on your motor. It’s required by pool owners in some states to conserve energy.

3. The pool pump is making strange noises.

A loud screech, steady hum, or quick and repetitive pops are all signs there is a serious mechanical issue. These problems all involve the pump’s motor and require a technician to assess if the motor can be saved by replacing individual pieces within the motor instead of replacing it.
