Do you need a new pool pump? You’ll know when your current one is going bad because it will make these loud and annoying sounds. These are sounds that’ll probably wake you up in the morning too. The only way those noises will go away is if you turn off the pump. However, it isn’t good for your pool water to leave the pump off for a long time. So, the only way to remedy the situation is to replace the pump with a new one.

When you go shopping for a new pool pump, you must select one that accommodates your budget and the type of pool that you have. This should be considered a long-term investment because you’ll be using this pump for a long time. That is why you need to understand the needs of your pool and the best pump features which will satisfy those needs. After you purchase the pump, try educating yourself on the various problems that may arise.

The Function of a Pool Pump

The pump is the main component of the plumbing system of your pool. If you don’t have a good pump, then the water in your pool will not circulate well. If the water doesn’t circulate well, then it won’t reach the filtration system and get a thorough cleaning. If the water is not cleaned, then it is left dirty, foggy, and loaded with bacteria and other nasty contaminants. This is not the kind of water that you should ever swim in.

Basic Features of Pool Pumps

Pool pumps have certainly evolved over the years. There used to be 1 type of pool pump only; not there are 3 types. They are as follows:

1) Single-Speed Pumps

The single speed pump is the original type of pool pump. It is called “single speed” because the impeller spins at only one speed. The motor’s horsepower determines this speed.

If you already have a single-speed pump and you need to replace it with a new pump, then this is the perfect time to upgrade to a dual-speed pump. Then you can have more efficient circulation and filtration in your pool.

Be aware that if you still decide to use a single-speed pump, it may be illegal in the state that you’re in. California and Arizona are just two states which have outlawed the use of single-speed pumps for pools. Research the laws of your state to see if single-speed is acceptable there.

2) Dual-Speed Pumps

Dual-speed pumps can be set to high or low speed. If you set it to high speed, it acts like a single-speed pump. If you set it to low speed, the water turnover in your pool won’t be as efficient. However, it will consume a lot less energy too. The volume of your pool will determine which speed is right for you.

3) Variable-Speed Pumps

Variable-speed pumps are the most expensive pool pumps, but they’re also the best. These pumps don’t use an induction motor. They use a permanent magnet motor, which is what you’d find in an electric car. There is less friction generated from a magnet motor too. This is what makes them more efficient.

You won’t consume as much power from a variable-speed pump either. Meanwhile, water turnover will be fast and efficient. And if you’re worried about loud noises, the variable-speed pump has fewer RPM than a dual-speed or single-speed pump. This means it is the quietest pump you could buy. Some utility companies may even give you a rebate for using this pump too.

Features of a Swimming Pool Pump

At this point, you may have some idea on which type of pool pump you’re going to get. Don’t run out and buy it just yet, though. You still need to think about the features of the pool pump first.

For instance, the horsepower of the pool pump is very important. If it has a lot of horsepower, then it will do a better job of turning over the water. That way, you don’t need to run the pump as often or for very long.

Of course, you need to consider the size of your pool, the pipes of your filtration system, and the filter size itself. If your filter is small, then having too much horsepower in your pump would be overwhelming for it. If you have 3-inch pipes, then a 3-horsepower pump would be good. But again, if your pool is small, then you’ll be paying more money on electricity with this setup. It is important that your pump isn’t too much for the filtration system to tolerate. At the same time, the horsepower should be powerful enough to turn over the volume of water in your pool at a consistent rate.

Another feature to consider is the voltage amount of the pump motor. Some pool pumps need 220 volts while others can use the standard 110 volts. If you have an above-ground pool, then it probably needs a pump that is only 110 volts. But if you have an above-ground pool, it likely needs 220 volts if it is big enough.

Some pool pumps must be plugged into an electrical outlet while others need to be hardwired. If you need it hardwired, this will require you to hire an electrician to integrate the pump into your electrical system.

Selecting the Best Inground Pool Pump Size

If you want your pool water to stay clear, it must all pass through your filtration system at least one time every day. The turnover rate refers to how much water is filtered. The entire volume of water in your pool must get pumped into the filtration system throughout the course of one day.

To determine the turnover rate of your pump, you must know the volume of your pool. A pool calculator can help you figure this out. Just search for one on Google.

After you’ve calculated the volume of the pool, divide the volume amount by 8. This will give you the number of GPH (gallons per hour) of water that gets pumped into your filtration system.

A lot of pool pumps nowadays use gallons per minute (GPM) instead of gallons per hour. To figure out the GPM, you just take the GPH and divide it by 60. Once you have the answer, this is the total GPM which must get pumped into the filter for a complete turnover of the pool’s volume.

Here are the formulas:

Volume / 8 = GPH

GPH / 60 = GPM

After you’ve performed these calculations, choose a pump size which is suitable for the GPM that your pool needs. If done correctly, the water turnover should be able to finish in 8 hours. It is okay to select a pump that has a slightly higher GPM than needed. But don’t choose one that has a lower GPM.

Pool Pump Troubleshooting

Pool pumps do not run well forever. There will come a point when a problem arises with your pump. If you learn about the most typical problems that a pool pump could face, you will be better prepared to deal with them whenever they present themselves.


The number one problem that occurs is pool pump leakage. This can happen if you have a damaged or worn impeller O-ring, shaft seal or thread sealant. The discharge pipe may also have shrunken threads which are causing this problem too.

In many situations, you can buy these parts at cheap prices and install them yourself if you need to replace your existing ones. This will save you money from having to hire a professional. Just find out where the leak is coming from, disassemble the system, replace the necessary part, and reassemble. Then your pump will work well again.

No Water is Being Pulled

If the pump isn’t pulling water into it, then the water won’t flow through the filter and get cleaned. Check to see if your system is clogged. This may be the reason why you’re having this problem.

Start by investigating both the pump baskets and the skimmer. If they’re not clogged, inspect the impeller and see if there is debris caught in it. If there is, then remove the debris so that the blade can be free to move fast again. Now check the pump by opening it up and remove any debris inside it as well.

If this still doesn’t fix the problem, then your suction line may have an air leak in it. Since air doesn’t have as much mass as water, then air gets sucked into the pump rather than the water. If there are leaks in any of the lines, patch them up.

Failure to Start the Motor

If the motor doesn’t start, check to see if the breaker has been tripped or not. If the pump doesn’t turn on when the breaker is on, then you’re having some kind of electrical issue. The only thing to do in this case is to replace the motor.

You may want to call a professional electrician to deal with the electrical system. This will ensure your safety.

Motor Shuts Off Extemporaneously

When the motor shuts off on its own, then it may be overheated. Inspect the air vents of the pump to see if they’re being blocked by anything. Try placing something over the pump to shade it from these obstructive outer elements.

If this still doesn’t fix the problem, you should call an electrician because there is probably an electrical problem there.

Noisy Motor

You can always expect some noise to come from your pump motor. But if you start hearing a lot of strange noises that you don’t normally hear, then it probably means there is a problem.

Sometimes it may just be a vibration issue. If that’s the case, put a rubber pad under the pump. But if you hear growling noises after doing that, then your pump isn’t sucking up enough water. Instead, it is sucking in air.

To address this problem, try to prime the pump. If the noise continues, inspect the intake lines to ensure they’re not leaking or clogged. If they are, then fix the leak or remove the debris that is clogging the lines. After that, the noises should go away.

If you hear a screaming sound coming from the pump, then the bearings are probably no good. Replace the bearings to fix this issue.

Replacement parts are very cheap. Just be prepared to spend a lot of time on the labor because you need to turn off the motor, detach it from the pool, and then take it apart. You need the right tools for the job, so make sure you have those.

Calling a Professional

If you’re comfortable repairing the pump yourself by disassembling the motor and configuring the electrical system, then go for it. You’ll certainly save a lot of money if you do the job yourself.

However, you need to have the necessary skills to do this job. This isn’t something where you can get “on-the-job” self-training. If you’re not experienced at these kinds of tasks, then hire a professional to do it for you.

The plumbing of your pool depends on a functional pool pump. If you don’t have the confidence to fix it, then you might end up making it worse. Have peace of mind by hiring a professional to repair it instead.

If you want to learn, perhaps you can watch the professional as they work on the pump. Take notes on what they’re doing so you can do the same thing yourself next time.
