How Long Do Pool Pumps Last? Your Guide to Pool Pump Life Expectancy

Pool pumps are the workhorses that keep pool water clean and balanced. They should last at least eight years, but when yours starts to wear down, you could end up with murky, algae-filled water. Before you dive head first into how to replace a pool pump, here’s everything you need to know about how long pool pumps last.

How Long Do Pool Pumps Last?

Pool pumps last between eight and 15 years on average. The pump's size, variety, and brand all factor into its life expectancy.

You can prolong the lifespan of a pool pump by:

• Pairing it with the proper filter

• Choosing the correct pool pump size (if the pump is too small, for example, it may have to run for longer and could burn out more quickly)

• Replacing the motor every eight to 10 years

• Changing your pool filter every two to three years

• Addressing early signs of a pool pump leak

• Opting for a variable-speed pump that runs only when necessary

Signs It's Time to Replace Your Pool Pump

Your pool pump will certainly let you know if it's time to call in a local pool repair team. Strange sounds, weak suction, and an overheating motor are all signs it either requires repair or is on its last legs. Knowing how long a pool pump lasts overall, however, can help you avoid a costly replacement.

Frequent Leaks

A leaking pool pump can create puddles around your pump or air bubbles shooting out into your pool. In some cases, tightening the connections of your pool pump will do the trick. If your pump is past its prime, it could be a sign the valves are no longer secure enough to function.

Odd Noises

Never ignore strange sounds coming from your pool pump. Anything above a low hum—including popping sounds, screeches, or grinding—is likely a sign that you either have a broken motor or a leak.

Shutting Off

Like all machines with a motor, a pool pump will shut off if something persistently keeps it from cooling down or running smoothly. If your pool pump frequently turns off, it could be a sign that it is overheating. A pool pump should never be too hot to handle with your hands. If you're concerned that it has heated to this level, avoid touching it and speak with a professional for guidance.

Low Filter Pressure

The gauge dial on top of your filter tank notes the pressure inside the system. The appropriate PSI will depend on your model. If the pressure is lower than it should be, it could be a sign of a clog or a leak in your pump. If the issues persist, it could be helpful to hire a pool electrician to ensure everything is hooked up properly.

Murky Water After Shocking

Shocking a pool is the process of adding chemicals to keep unwanted organic material in your water at bay. If you find that your water quickly turns murky or grows algae, it could be a sign your pool pump needs a look.

Higher Electricity Bills

While it can be hard to pinpoint that it is coming from your pool motor, a sudden uptick in your utility bills can also indicate a problem. The price to run a pool pump should range from $30 to $150 a month. If your bill is significantly higher than that, it may be that your pool pump is working overtime to function.

Pool Pump Replacement Costs

If replacement is the best option, the cost of a new pool pump averages about $1,750, but you'll find some budget-friendly brands for as little as $300. If you can, opting for pool pump repairs can save you a lot of money. Pool pump motor repairs, for example, range between $250 and $650. Additional pool repair costs, such as filter and pipe replacement, are often necessary investments to prolong your pool pump's life expectancy.
