In-ground pools need high-HP pumps with 1.5” to 2” plumbing. Almost all in-ground pools have PVC pipes, which means your pump needs to have the proper fittings. You can choose from a variety of brands, speeds, and many other features to decide which pump is the best for you. However, some pumps are much better than others.
The best pool pump for in-ground pools is the Hayward MaxFlo VS Pump. This 1.65HP pool pump saves up to 80% of energy compared to single-speed pumps. It has multiple speed settings, boasts up to 160 gallons per minute, and includes unions for almost any in-ground swimming pool.

In this post, I’ll cover everything you should know about choosing an in-ground pool pump. I’ll also include reviews of each of the best in-ground pool pumps on the list. Let’s get started!

What to Look For in an In-Ground Pool Pump
Finding the right inground pool pump in a sea of pumps can be difficult. There are countless specifications, brands, and other features to consider. However, I’ve narrowed it down to three must-have factors. If you want to know which pool pump is best for your inground pool, look for these three specs:
- Gallons per minute: Every pump has a label with its gallons per minute or gallons per hour. This measurement shows how many hours it’ll take for the pump to cycle all of the water in the swimming pool. Above-ground pools should go through two full cycles every day if possible.
- Horsepower: A pump’s horsepower determines how much power it provides. If you have a 2.5HP pool pump, it can move multiple water features, vacuums, and water through the system. However, large pools take up a lot of horsepower, so it’s important to find the right balance.
- Speed options: You can choose between single-speed, two-speed, and variable-speed pool pumps. VS pumps are the best choice for energy efficiency, low-noise output, and versatility. However, they tend to be a bit pricier than the other others. Two-speed pumps are quite rare these days.
I’ll dive further into each of these essential details below.
Gallons Per Minute (GPM)
Your new pump’s gallons per minute is one of the most crucial parts of the specs sheet. Every pool pump should have a similar GPM to the filter. For example, if your pool filter can operate with 150 gallons per minute, the pump should be around 120 to 180 gallons per minute. Too much of a deviation can cause the pool pump to make loud noises and overheat.
The best way to determine the gallons per minute that your pump needs are with the following formula:
- Multiply the (length x width x depth) x 7.5. This number will tell you how many gallons are in the pool. Write it down so you can know how much of each chemical you’ll need and what size equipment the pool calls for.
- Multiply the potential pump’s GPM by 60 to get the GPH (gallons per hour). This number will show you how many hours it takes to cycle the whole swimming pool. Aim for a total of three to four hours if possible.
- Find a pool pump that cycles the gallon total one to two times within 6 to 8 hours. For example, a 150 GPM pump cycles 9,000 gallons per hour. This means that you can cycle a 27,000-gallon swimming pool in three hours or twice in six hours.
Most inground pool pumps range between 70 to 200 GPM. Keep in mind that you don’t always need a higher GPM, so it could be a waste of money and energy. Instead, use the aforementioned formula for accurate results.
Keep in mind that using the incorrect or unlabeled plumbing size will alter the GPM. For example, if the pump is designed for 2” plumbing and you use a 1.5” adapter, you’ll reduce the GPM. Furthermore, the headway (also known as the space between the pump’s suction and the skimmer) can affect the GPM.
Some people prefer a lower GPM if they have a variable-speed pump. You can run the pump at slower speeds to reduce the GPM and keep the water moving longer. This process provides two benefits:
- It reduces your pump’s energy consumption.
- It prevents algae because algae has a harder time growing when the water is moving.
Horsepower
The next most important statistic is your pump’s horsepower. The horsepower is a measurement that shows how much power your pump can supply. You need more horsepower based on these two metrics:
- Your pool’s gallon total
- The number of water features and vacuums your pool uses
If you don’t have water features or vacuums, you can rely on a basic HP (1.5 to 2.5) for almost any inground swimming pool. Choosing the wrong horsepower can cause a lot of pool pump problems, such as not enough water flow, impeller cavitation, and shredding the filter media.
Review the following table to know which horsepower is right for your inground swimming pool.
Pool Gallon Total | Recommended Pump Horsepower |
Below 5,000 gallons | 0.5 horsepower |
5,000 to 10,000 gallons | 1 horsepower |
10,000 to 15,000 gallons | 1.5 horsepower |
15,000 to 25,000 gallons | 2.5 horsepower |
Over 25,000 gallons | 3 horsepower |
Pro Tip: If you have a lot of water features and heavy-duty pool vacuums, you could get a higher horsepower. For example, a 13,000-gallon pool with water features and a suction-side pool vacuum could jump to a 2.5-horsepower pump instead of the recommended 1.5-horsepower pump.
Speed Options
Inground pool pumps come in the following speeds:
- Single-speed pumps: Single-speed pool pumps are the most common type of pump on the market. They’ve been around longer than any pump type. These pumps have one speed, which is typically around 3,000 RPMs. While they’re great for vacuums and water features, they tend to use more energy.
- Two-speed pumps: Two-speed pumps were the low-energy answer to single-speed pump problems. You can set a two-speed pump to a lower RPM (around 2,000 RPMs) or the traditional 3,000-RPM range. Every pump has unique speeds, but you can cycle between two options for the occasion.
- Variable-speed pumps: Variable-speed pumps are the best option on the market. The best variable-speed pumps let you change to any RPM whenever you want. You can run a VS pump 24 hours a day at a lower speed or switch it into high gear for water features and vacuums. They also save tons of energy and produce less noise.
Single-speed pumps have the advantage of being much cheaper than VS and 2S pumps. However, they’re louder and don’t last as long. Furthermore, they use up to 80% more electricity, which means they cost more in the long run. Since two-speed pumps are overshadowed by VS pumps, there aren’t too many worthy options available these days.

One of my favorite parts of this design is the bolted lid. Two threaded knobs secure the lid. Loosen them to remove the lid and reveal the debris basket. The basket is significantly bigger than most pump baskets I’ve seen in the field. It can catch and hold leaves, algae, sticks, hair, and more. The larger basket prevents you from having to empty it too often.
The Hayward Super series is an easy choice for beginners and those who want a low-maintenance pool pump.

Perhaps one of the best features is the simple display. Those who haven’t used VS pumps will enjoy the SuperFlo’s user-friendly interface. There are very few buttons, all of which provide optimal control. You can quickly cycle through the time, speed, duration, and watt consumption with the menu button on the display.
This pump also includes an optional bolted base. The base platform limits vibrations and prevents the pump from cracking during an earthquake. You can use cement bolts to secure the pump’s motor to the ground. I highly recommend using the base, whether or not you use bolts. It’s worth reducing the noise output.
Bottom Line: The Pentair Superflo has been one of the most popular variable-speed pumps in the industry. It’s the affordable, widely used version of the Pentair Intelliflo (the 2.5 HP variant).
