A swimming pool is a precisely calibrated ecosystem where every component functions flawlessly to maintain the water’s cleanliness and freshness.

The human body is the ideal comparison to illustrate how each component is essential to the pool’s overall health. Half-naked human beings may be seen swimming laps and performing cannonballs in swimming pools worldwide.

Let’s examine each of these components individually.

The Pump: the heart 

Let’s begin there since the pump is the pool’s beating heart. Like how the human heart sucks in all the deoxygenated blood and pumps out fresh blood to the rest of the body, the pump’s role is to suck in all the dirty water and then pump out fresh, clean water.

An impeller, a motor-powered component of the pool pump, spins quickly enough to generate a vacuum that draws the water into the filtration system.

Our comparison to the human heart is somewhat flawed here because the pump’s power is expressed in horsepower, but you get the idea. The majority of pumps fall between 3/4 and 3 horsepower.

The bigger the pool, the more horsepower you will need.  

The Skimmers: the mouth

The contaminated water is drawn in by the pump’s suction strength to be filtered, but how does it get there? The skimmers or the mouths of the pool are where it starts. All in-ground pools have small to medium-sized rectangular apertures on the inside walls. You might fall into the ones you feared as a child.

They consume all the floating microorganisms, including germs, insects, dust, hair, trash, dust, and murky water. A comparable function is performed by the drain or drains at the bottom of pools.

Suction lines: the veins

Water that has been through the skimmer enters the suction lines, which are essentially PVC pipes that carry the contaminated water to the pump. It’s comparable to how your veins deliver anaemic blood to your heart.

Filter: the kidneys

Although they collaborate closely, the pump and the filter are very different objects some people mistakenly believe to be the same.

The filter handles all the dirty work by capturing all the dirt and particles and cleaning the water. Imagine it as your kidneys, which are responsible for removing waste from the blood.

Return lines: the arteries

Similar to the suction lines, but pointing in the other direction, The pump returns the purified water to the pool through these PVC pipes once it has been filtered. You could say they are the arteries of the pool.

Return: the eyes

These tiny motorised jets can be seen on the pool’s inside walls. The filtered water is sent back into circulation throughout the pool after they give it a little extra kick. Additionally, they assist in rerouting the contaminated water to the skimmers.

Although they are unlikely to allow your pool to see, they are frequently called “eyeballs” because of how they appear.
