The Ultimate Guide to Choosing a Swimming Pool Water Pump

Swimming pools are a fantastic addition to any home, providing endless hours of entertainment and relaxation. While it’s easy to focus on the visual elements of your pool, such as the color or design, selecting the right equipment is crucial. The swimming pool water pump is a vital component in your pool’s overall function, ensuring that your pool water circulates correctly, remains clean, clear, and safe for swimmers.
In this article, we will discuss just how crucial it is to choose the right swimming pool water pump, as well as how a pool pump works, and the factors you should consider when purchasing one. With the information in this guide, you can make an informed decision and select a pool pump that will keep your pool functioning at its best, all summer long.

Understanding Pool Water Pump Basics

Types of Pool Water Pumps

There are mainly two types of pool water pumps, single speed and variable speed pumps. Single speed pumps are designed to run at a constant speed and operate at full power throughout the day. They work by pulling water from the pool through the skimmer and main drains, and then pushing the water through the filter and back into the pool. Variable speed pumps, on the other hand, are equipped with advanced technology that allows them to adjust their speed according to the pool’s needs. They can operate at a lower speed which eventually generates less noise, and consume less power.

Factors to Consider when Choosing a Pool Water Pump

Before purchasing a pool water pump, there are some critical factors you should consider. Firstly, you have to consider the size of your pool, the desired flow rate, and the type of filter you are using. Secondly, you have to consider the pool’s plumbing system, including the diameter of the pipes, the length of the existing piping, and the number of inlets and outlets. You should also consider the noise level of the water pump, as well as its energy consumption, and maintenance requirements.

Size and Horsepower Requirements

The size and horsepower of a pool water pump depend on the size of your pool and the desired flow rate. If your pool’s volume is more significant than 20,000 gallons, you will need a 1.5 HP or two-speed 1 HP pump. But, if your pool’s volume is less than 20,000 gallons, you can get by with a 1 HP or below pump. The pump’s size will also determine how much water it can move in a given period. You will have to calculate how much water you need to circulate per hour to maintain a clean pool, and then choose a pump with the appropriate horsepower and flow rate to achieve that amount. Generally, a pump should circulate water through the filter at least once every eight hours.

Evaluating Your Pool’s Needs

Pool size and capacity

A swimming pool pump’s size is determined by the size and capacity of the pool it’s pumping water for. The size of the pump must produce enough flow to filter all the water in the pool in 8-10 hours. When considering the appropriate pool size, they are usually categorized by gallon capacity, such as small, medium, and large pools. Larger pools generally require more pump horsepower, while smaller pools can use less. A good rule of thumb when choosing a pool pump is to select one that produces a flow rate of about 1 gallon per minute per 10 sq. ft of pool surface area.

Type of pool and usage

The type of pool and intended usage also plays an important role in choosing the right swimming pool pump. For example, a pool that is used frequently with high traffic will require a more substantial and durable pump than a smaller pool only used occasionally. An above-ground pool frequently requires a smaller pump with lower horsepower since they usually hold less water than in-ground pools. Indoor pools will require a quieter pump than an outdoor pool, where noise might not be a significant issue.

Water features and accessories

The different accessories and features in your swimming pool may affect the type of pump needed. Water features such as waterfalls, fountains, and slides will require larger pumps with more horsepower to maintain adequate flow. Similarly, pool cleaners, vacuum heads, and other similar accessories will require a powerful pump to work efficiently. If you have solar pool heating, you may require a bigger pump with a variable speed motor to make sure the system maintains efficient heating. All these factors must be assessed to select the most appropriate model for the swimming pool.

Energy-efficient pool pump options

Variable Speed Pumps

The variable speed pumps are the most energy-efficient option for the swimming pool. These pumps are designed to adjust the speed of the motor according to the pool’s needs and reduce the energy consumption significantly. Variable speed pumps use up to 80% less energy than single-speed pumps, resulting in substantial energy savings and a lower electricity bill.

Two-Speed Pumps

Two-speed pumps have two-speed options, low and high, and are more energy-efficient than single-speed pumps. They allow the user to switch between speeds depending on the pool’s requirements, which helps in saving energy. Two-speed pumps use up to 50% less energy than single-speed pumps.

Single Speed Pumps

Single-speed pumps are the most common and least energy-efficient pool pump. They run at a constant speed, which can lead to high energy consumption and increased electricity bills.

Energy Consumption and Savings

Energy Efficiency Ratings

When choosing a pool pump, make sure to check its energy rating. The higher the rating, the more energy-efficient the pump is. Energy efficiency ratings range from 1 to 4, with 4 being the most energy-efficient option.

Proper Sizing

Choose a pump that is the correct size for your pool. An oversized pump will result in higher energy consumption, while an undersized pump will not be able to clean the pool thoroughly. A correctly sized pump will operate more efficiently, saving both energy and money.


Regular maintenance of your pool pump is essential in reducing energy consumption. Clean the pump basket, replace worn-out parts, and check for leaks regularly to ensure that the pump is running at optimal efficiency.

By choosing an energy-efficient pump that is correctly sized, regularly maintained, and has a high energy rating, you can significantly reduce energy consumption and save money on electricity bills.
