Buyer’s Guide

To help you choose the best suitable pool pump, we created a brief buyer’s guide. Read on to find out what to look for in the perfect filtration equipment.

Size/Flow Rate

Accurate pool pump size calculation is crucial for maintaining clean water and maximizing energy savings. The general rule is that a pool pump should filter all the water in under eight hours. However, an overly powerful pump may consume unnecessary amounts of energy.

Pool pump size is closely related to its flow rate and is measured in gallons per minute (GPM). To determine how large a pump you need, calculate your pool’s volume.

Next, multiply the width, length, and depth of the pool. Then, multiply that result by 7.5 (the number of gallons in a cubic foot). The result is your pool size in gallons.

If you have a round pool, treat it as square or use this formula:

  • First, take its radius and multiply it by two and then by 3.14.
  • Then multiply the result by your pool’s depth to get the volume.

Finally, you should convert the result into the minimum required GPM. Here’s how to do that:

  • One turnover may not be enough for saltwater pools, so it’s recommended to multiply the pool’s volume by two to get the total water volume a pump must filter in a day.
  • Divide the total amount of water in gallons by 24. The result will be how many gallons the pump needs to filter in an hour. Then, divide this number by 60 to get the minimum required GPM rating.

For example, you have a 20-ft. wide, 40-ft. long, and 6-ft. deep pool. The pump running time is eight hours. Thus, 20 x 40 x 6 x 7.5 = 36,000 gallons. Assuming it’s a saltwater pool, two turnovers are needed, so we multiply this number by two: 36,000 x 2 = 72,000 gallons. Then, we calculate the GPM:

72,000: 24 = 3,000 gallons per hour

3,000: 60 = 50 gallons per minute

So, the minimum pump flow rate for a 20 x 40 x 6-feet pool is 50 GPM.

The maximum flow rate is determined by the plumbing. The plumbing flow rates are fixed:

  • 1.5-inch plumbing handles up to 43 gallons per minute
  • 2-inch plumbing handles up to 73 gallons per minute
  • 2.5-inch plumbing handles up to 120 gallons per minute

If you have several pipelines, multiply the flow rate by their number. For instance, the maximum pump flow rate for a pool with two 2-inch lines would be 73 x 2 = 146 GPM. If your pool’s plumbing system differs from the industry standard, we advise contacting a professional for a consultation.

Installation Requirements: Wired vs. Plug-In

Although professional help is never wasteful when it comes to electrical wiring or plumbing, some pool pumps can be installed without an expert hand. This mainly relates to plug-in options. If you choose a plug-in pump, make sure the receptacle is GFCI-protected to prevent electrocution. Power outlets located within 10 feet of the pool must also have a twist-lock style plug to avoid exposure to splashes.

Wired pool pumps are connected to your house’s electrical system. The electrical supply must be compatible with the pump’s voltage, phase, and cycle. Wiring installation is a hazardous and complicated process. We highly advise hiring an experienced contractor to perform any electrical work.

Pool Compatibility: Inground vs. Above-Ground

Most modern pool pumps are designed for compatibility with in-ground pools. Technically, pumps for in-ground and above-ground pools don’t differ much.

Many of them are suitable for both pool types. However, if you have an above-ground pool, we advise checking the characteristics in advance to avoid installation issues. Furthermore, above-ground pools are generally smaller than in-ground options and require an appropriately sized pump.

Speeds and Settings

The more speed settings your pool pump has, the higher your energy savings will be because energy consumption can be tailored to your needs.

Higher speeds are perfect for extensive water filtration and are required when many people use the pool simultaneously. However, for daily use, a slower pace is preferable. It has numerous benefits, such as:

  • Significant energy savings. Due to the pump affinity law, savings grow disproportionately to the decrease in pumping speed. In other words, it’s cheaper to run the pump slower and longer than faster for a short period
  • Slower speed helps to maintain your pool equipment in good condition. Fast water flow may increase the wear and tear of your filtration system and pipes
  • Improved sanitization. Chlorine necessary for pool sanitization is usually unstabilized. Sunlight causes it to dissolve faster. When chlorinated water runs through the pump, it’s preserved from the sun. In other words, the longer the pump runs, the more chlorine remains in the water, and the cleaner your pool is.

Overall, variable-speed pumps are the best option. However, they also have a higher initial cost than double-speed and single-speed pumps. If you don’t use your pool frequently or it isn’t large, purchasing a single-speed pump may be a better idea. They’re much more affordable and don’t have any complicated settings.

Double-speed pumps are an optimal choice for pools with attached spas. You can use higher speeds for the pool and lower ones for the spa, which usually is smaller.

Be aware, though – as the flow rates can’t be adjusted, the lower speed may be insufficient for your pool. So before getting a double-speed pump, conduct all the necessary calculations to ensure that both settings are suitable for your pool.

Horsepower

Although previously we sized pool pumps in gallons per minute, most manufacturers don’t advertise their product power in such measurements. Instead, the pump power is measure in horsepower. The flow depends on a scope of factors beyond the product itself, including plumbing, filter, the elevation of the pump, and others. These factors may create head resistance.

The average head resistance of most pools is 40 feet. Thus, a typical 1-horsepower motor can move 100 gallons of water per minute. But, considering a 40-feet resistance, the actual amount of water may be lower by half.

With that in mind, 0.5-horsepower pumps are the best fit for small pools with up to an 11,000-gallon capacity. A 1-horsepower pump is suitable for medium-sized pools with up to a 26,000-gallon capacity. Larger pools require at least 1.5-horsepower pumps.

Although the general recommendations are pretty straightforward, your pool’s heat resistance may differ from the average in practice. For example, if the pump is located further than 40 feet from the pool or is on a lower level, the resistance will be greater.

Consequently, you may need a stronger pump. Hiring a professional to calculate your pool’s heat resistance may be highly useful for correct pump sizing.

FAQ

If you still have some uncertainty regarding choosing and operating a pool pump, we’re here to help. In this section, we’ll provide answers to the most common questions related to the topic.

What Does a Pool Pump Do?

As the name suggests, a pool pump moves water. Technically, pool pumps are called centrifugal pumps as they use centrifugal force, circulating water from inlet to outlet. This single action serves an essential purpose, though.

First, a pump pulls water from your pool through drains and skimmers. Then, it circulates the water through filters and returns clean water into the pool.

A pool pump is the heart of a pool’s filtration system. Its main components are a strainer basket, motor, and impeller. The latter is the only moving part of a pump, propelling water at high velocity with fan-like blades. Closed face impellers are the most energy-efficient type of impeller and, therefore, the most common in modern pool pumps.

The pump basket collects debris to prevent clogs and damage to the impeller. It also helps to keep your pool clean from any floating material. This basket can later be removed and emptied.

As with many other mechanisms, a motor is the pump’s power source. Modern pool pumps typically have one of the following motor types:

Variable Speed Motor

It’s designed to operate at different speeds to reduce energy usage and perform specific tasks. As a result, it’s the most cost-effective in the long term and is ideal for frequently used pools.

Double-Speed Motor

This type of motor keeps the pump working either low or fast. Thus, it often offers a perfect balance between versatility and cost. However, the motor speed can’t be adjusted, and you must make sure both settings are suitable for your pool size in advance.

Single-Speed Motor

It’s the simplest and initially most inexpensive motor type. However, such motors consume more energy than variable speed options. As a result, they’re a perfect fit for a pool that is used rarely.

Is It Better to Run a Pool Pump at Night or Day?

In many areas of the U.S., running electrical appliances at night is more cost-effective due to lower energy rates. Plus, it’s nice to have a pool clean and ready for swimming from early morning. So, it would seem that running the pool pump at night makes more sense, though, in practice, it isn’t that straightforward.

Generally, it’s best to run your pool pump during the hottest times of the day. That’s due to the chlorine contained in water, which is necessary for fighting bacteria and algae.

If the chlorine is unstabilized (a common occurrence), sunlight can cause depletion, rendering sanitization useless. Water moving around prevents chlorine from getting burnt out as fast, consequently saving your pool from contamination. Chlorine doesn’t deplete during the night, and running a pump will only decrease sanitization effectiveness.

Running your pump during the day will also ensure that pool users don’t wreak havoc on the water’s quality. People inevitably contaminate the pool with dirt, sweat, sunblock, and other matter, changing the water’s chemical balance.

Overall, running your pump for eight hours during the day is the best practice to maintain a clean and safe environment.

For pool owners for whom energy savings are a significant concern, it may be wise to split the pump running times. It’s a widespread practice in Southern states, where the cost of electricity is relatively high, but the sun’s heat is plentiful. For instance, it could run for four hours during the day and the same time during the night. This way, a significant part of chlorine is preserved, but the energy bill doesn’t skyrocket.

Should I Run Pool Pump on High or Low?

The question any owner of a double-speed or variable speed pool pump asks when first starting it up is, ‘Which speed do I choose?’ Naturally, every speed has its pros and cons, otherwise providing different options wouldn’t make sense.

However, your pool pump should be able to filter all the water in eight hours or less. Generally, any speed is suitable so long as it meets this requirement.

High speeds are great for pools that are used extensively. If many people are using the pool at the same time, running the pump on maximum settings will ensure that water remains clean. It may seem that energy consumption evens out if you run the pump at twice the speed for half the time.

However, in practice, high speeds consume significantly more energy, resulting in increased energy bills. It happens due to a pump affinity law, which states that energy consumption grows disproportionately larger the more you increase the pump speed. Thus, high speeds are better for specific occasions rather than for daily use.

Electricity savings aren’t the only reason for choosing low speeds for daily use. The slower the pump runs, the less noise it makes. This may seem like a minor advantage, but pools are made for relaxing, and some high-speed pumps can be extremely noisy.

Lower speed also reduces the wear and tear of your pool equipment, including filters, heaters, and chlorinators, extending their lifespan.

Finally, when the pump runs at a slower pace, it filters water for longer periods. Consequently, it distributes chemicals more evenly and captures more contaminants. This helps to achieve cleaner water and fight algae buildup.

Should You Run Pool Pump in Rain?

Yes. Rain contains different elements than your pool water, so it causes numerous chemical changes. Usually, rain is more acidic than pool water. Consequently, the overall pH level may drop. This may cause skin irritation or damage your pool’s heating and filtration system.

Rainfall also provides perfect conditions for breeding algae, as it’s enriched with nitrogen. Thus, an algaecide is of great help here, though it may be insufficient during heavy rainfalls.

Plus, rain often comes side by side with the wind that brings twigs and leaves to the pool. Additional debris may clog the filtration system and lead to serious issues if untreated.

Optionally, you can run it right after the rain stops, but it’s necessary to do so before your next pool use. Running your pool pump during rain helps to deal with chemical changes right away. It’s also easier to filter contaminants gradually rather than in one go, and you can start swimming earlier after the rain ends.

How Much Does a Pool Pump Increase Your Electric Bill?

There’s no universal answer to this question. It depends on the pump type and running speed, size of your pool, frequency of use, and energy cost in your area. However, we can estimate based on the national average energy cost of 11.8 cents per kilowatt-hour (KWh) of power. Therefore, a typical pool pump used daily may add about $50-150 to your monthly energy bill.

Of course, you can decrease energy consumption by implementing a wise pump running approach. For instance, if your state offers cheaper energy at night, you may run the pump partially at night. However, we don’t advise shifting to night-time filtration entirely as it may affect the pool’s cleanliness.

Pump efficiency also plays a significant role in energy savings. Invest in smaller, more efficient equipment. If you only use the pool occasionally, don’t run the pump every day. A regular pool cover will ensure that no debris, leaves, or other matter gets into the pool when it’s not in use. When needed, you can shock the pool and use the high pumping speed to get it ready for swimming faster.

As for the running time, six hours is the recommended minimum. An automatic timer will ensure that your pump always starts on time and never works longer than required. Some modern pumps even have a built-in timer. Finally, choose a slower pumping pace for daily use. The pump affinity law states that energy savings grow disproportionally as pump speed decreases.

Invest in Efficiency

Hopefully, our guide has helped you understand which pump your pool requires. Investing in efficient, modern pool equipment pays off in the long term. Combined with a wise use strategy, a new pump may significantly decrease your energy bill. Most importantly, the best pool pump will ensure your pool is safe and clean at all times.
