Get to Know the Parts of Your Swimming Pool – Clean & Clear Pools

Written by Lisa Hallett Taylor and published on

Anyone who’s ever taken a dip in a creek or lake might think that a swimming pool is a reasonably simple apparatus. However, it is a very complex system that must be correctly assembled by a qualified pool builder to work precisely.

Before you even get started with a pool project, you should understand a little more about the construction of your new favorite hangout. This will shed some light on the various expenses associated with the installation and upkeep of the pool. Beyond the actual pool, the parts we’ll address are involved in the filtration, circulation, and heating of water.

Getting to Know the Parts of Your Swimming Pool

How intimately do you know your swimming pool? If you maintain it yourself—even part-time—then you should know about some of the inner-workings of that big body of water in your yard. Let us help you take the mystery out of some of the main components of your swimming pool, so at least if the pool repair person is explaining something, you won’t have a spacey, far-off look in your eyes as he/she uses terms like surface skimmer and filtration system.

First, you may have heard of the term backwashing. You can’t go to a pool supply store and ask to buy a backwasher. They might know what you’re talking about, but you’ll give away that you don’t know the correct terms for the parts of your pool. Whether you buy your pool equipment from a local retailer or shop online, this is an important word to know for general pool maintenance.

What Is Backwashing?

The backwashing process reverses the flow of water to flush out contaminants from a swimming pool filter. It should be carried out until water runs clear through the waste line.



Without coping, the steel projecting from the pool’s walls would be exposed, and water could get behind the pool shell. Discover other functions of pool coping.


DE Filter

Not surprisingly, DE, aka diatomaceous earth, is the main ingredient in a DE pool filter. Discover why many pool owners consider DE filters to be the best kind of pool filter.


Gas Heater

While solar has been grabbing all the attention, gas heaters still account for most of the heaters in residential pools. Discover why they are still a good idea for heating small pools and spas.


Main Drain

In most residential pools, two main drains are located at the bottom — the deepest part of the swimming pool. Discover which one the main drain is, and it’s primary purpose.


Pumps and Motors

Working in tandem with the motor, the pool pump draws water from a pool or spa and somehow returns it back to the pool or spa. Find out how this happens and why it’s an integral part of your pool.


Sand Filter

 What? Another type of filter for your pool? Too many choices. Learn the pros and cons of this type and why it might be the right type for your particular swimming pool.



Most residential pools have skimmers, which help with debris collection. Find out the other functions of a skimmer and the types of debris it collects (ick alert!).



Weirs are best friends to skimmers and you rarely see one without the other. Find out why.
