Why Does a Swimming Pool Pump Need to be Replaced Early?

My pool pump is not working and I just replaced it two years ago.   Shouldn’t it last longer?   This was a question that a former customer said to us on the phone.   We had replaced his motor only two years ago.

Swimming pool pumps are work horses but they need to be cared for in order for them to work for their normal “life span.”

A swimming pool pump that is properly cared for should last a few years.   That is a reasonable life span.   Many pool pumps last even longer than that.

Why would a swimming pool pump need to be replaced earlier?

This is a question that people ask us when they call to tell us that their pump died.

Here are the main reasons that cause a pool pump to die early.

Water Chemistry not Properly Maintained
Maintaining pool chemistry is essential to increasing the life span of pool equipment.   Over time when the pool chemistry is not maintained, it can cause corrosion on the pool equipment.   This corrosion decreases the effectiveness of the pool equipment and it will eventually break down.

Pool chemistry has three main components,  Chlorine, PH and alkalinity.   If chlorine levels are not maintained properly, then the pool will get algae.
If the PH and the alkalinity levels are not maintained properly, then it will cause corrosion on pool equipment, specifically the pool pump motor.
This is a common problem that we see with people who do not employ a good pool service or take care of the pool themselves.   Most people just don’t have a correct understanding of the importance of good pool chemistry.
When maintaining your pool, it is easy to let the PH and alkalinity slide and focus solely on proper chlorine levels in the pool.   But, maintaining these two chemical levels in a pool is very important.   They work in tandem with chlorine levels.  All of them need to kept in proper balance in order for the chlorine to properly do its job.
Pump Working too Hard or Getting Too Hot
A pool pump is designed to work at a specific speed and temperature.   If you touch the pool pump motor, it should feel hot like a frying pan.

You don’t leave your hand on it or it will get burned.   You can check the temperature of a pool pump by using a temperature gage for electrical equipment.

A pool pump motor will heat too quickly when the pool pump is working too hard.   A pool pump will work too hard when the pool pump is not properly sized for the filter that not properly sized for the pool filter.
A properly sized pool pump will have the right amount of horsepower for the pool filters that it is attached to.

If the pool pump is too small for the filter than it will have to expend more electrical energy in order for it to keep up with the demands of the pool filter.

Also, a pool pump will have to work harder when the pool pipes are not properly sized for the pool and the pool equipment.   Properly sized pool pipes will allow the water to flow efficiently to the filter so that it can be filtrated, cleaned and recirculated back into the swimming pool.
Keeping your Pool Open Year Round
We are located north of Atlanta.   A large percentage of our customers keep their pools open year round.   This means that the pumps are having to work even through the cold winter months.

Good pool pumps are designed to work year round.   But, if the chemicals are not properly maintained and the pool is neglected in the off season months, this will contribute to the pool pump motor going out early.

Water Damage and Debris Clogging
Northwest Georgia is very hilly.   We often service pools that are at the bottom of hills.   When there is significant rain, the water flows to the bottom of the hill and can damage the pool equipment.   Having the pool equipment flooded repeated times will cause it to go out.
Also, if the pool pump is not kept free of leaves and other yard debris, this can also cause it to die and quit before it’s manufactured life span.   The debris clogs up the vents and the pool pump will quit before it’s time.
Solution to Pool Pump Quitting Early
The average life span of a pool pump is only a few years.   You can amage (ie flood, mud, debris around motor, not keeping leaves away from vents)
In the last five years, there have been advancements in variable speed pool pump technology.   A variable speed pool pump solves the problem and increases the life span of your pool pump from 3-5 years and sometimes even longer.
A variable speed pool pump allows the operator to program the pool pump to operate and higher speeds during the hot summer days.   And, when it’s colder in the winter, the pool pump can operate at a lower speed.   The saves the motor and increases the lifespan of the equipment.
It is an investment to purchase a variable speed pool pump but the money saved on electrical costs in the first year will almost cover what was spent on the pool pump.
