Understanding Your Swimming Pool Equipment and Parts

Understanding Your Swimming Pool Equipment and Parts

Learn about the different components of your pool’s anatomy.

Just like the human body, your pool is a precision system — with every part working together to keep it running smoothly. Similar to how your heart pumps, keeping your circulation moving, your pool’s filtration system circulates the water in your pool to make it comfortable, clear, and ready for hours of enjoyment.

This system’s responsibility: To keep that large body of water you use each day sparkling clean (and a good system will also do so while conserving energy).

And just as you need regular checkups to maintain your health, your pool requires regular maintenance as well.

To simplify pool maintenance and operation, a swimming pool must have properly working equipment along with the right chemical balance. Everyone wants a pool with clear, clean water. Water clarity refers to how it appears, while water quality is how clean it is. Water quality is maintained through a proper balance of chemistry, circulation, and filtration—if water is properly “balanced” you should clearly see the bottom of the pool.

Pool Equipment and Parts: The Basics

The filtration system is made up of several parts, just like the human circulatory system. There’s a pump, a filter, a chlorinator, and possibly a heater. The filtration system’s primary purpose is to remove dirt and debris by filtering water and distributing the chemicals that will keep your pool sanitized.

Whatever type of in-ground pool you might have, its equipment should be made of quality, non-corrosive materials. Whether you are building a new pool or remodeling an older one, it’s important to use high-quality, durable and energy-efficient equipment to conserve energy and maintain reasonable electricity bills.

Pool Equipment: The Pump

A pool pump is a type of centrifugal pump, that circulates the water through the filtration system where it will be cleaned and heated (if it’s equipped with a heater). A pump is usually located on the intake side of the filter, which allows it to push pool water through the filter, heater, and other components. There are a few options when choosing a pump — single speed, two speed and variable speed. Compared to single and two speed pumps, variable speed pumps provide the highest energy savings by allowing the motor to automatically adjust to operate at lower, energy-efficient and cost-saving speeds, depending on the immediate needs of the filtration system.



pool filter options

Pool Equipment: The Filter

Working in conjunction with the pump, the filter traps debris, hair, dirt, sand and other fine particles that you can’t see. Basically, pool water enters the filter, moves through the filter medium, and is comes out clean as it leaves the filter tank.

There are three types of pool filters:

  • Diatomaceous Earth (DE) are able to trap the finest particles and provide the best filtration resulting in clear, glassy water.
  • High-rate sand filters are popular because they are easy to install and maintain, and don’t need frequent replacing.
  • Cartridge filters are a cost-effective and popular choice, cartridge filters require no backwashing.


When selecting a filter, make sure it’s appropriate for the number of gallons per minute that the pump is equipped to deliver. Your filter selection may depend on city or regional code requirements, the preference or recommendation of your builder or the specifications of the manufacturer of the pump and/or filter. Filters won’t remove bacteria or other organisms (that’s where your balanced chemicals come in).


swimming pool chlorinator

Pool Equipment: The Chlorinator

Speaking of chemicals, the job of the chlorinator is to add these sanitizing agents to your water. There are different options for chlorinators that either require you to replenish chlorine with chlorine tabs, liquid chlorine, or ones that actually create the chlorine through a natural process using salt technology (Salt Chlorinator).






swimming pool heater

Pool Equipment: The Heater

A heater can extend the swim season and allow you to swim comfortably early in the morning or at night. Pools can be heated by gas, electricity, or the sun in some areas. Gas Heaters and Electric Heat Pumps are the most common types of heaters, and each has it’s own advantages based your specific application. Your builder or pool pro will help you determine the appropriate heater type and size for your pool. Jandy’s heaters are designed to lower plumbing costs and increase energy efficiency; the JXi™ series comes in natural gas and propane models and offer optional integrated flow bypass technology, allowing you to bypass the heater for increased energy savings.




cleaning the skimmer ogden pools

Pool Equipment: The Skimmer

Another important part of the pool support system is the skimmer, which is usually built into the pool and is designed with a basket to easily remove debris. A skimmer connects to the pump intake and draws debris into the filtration system. Skimmers can be sold as extra parts or adaptors for automatic or robotic pool cleaners.

These basic pieces of equipment are vital parts of your swimming pool. Maintain them, treat them well, and they’ll work together to give you a beautiful, healthy pool.
