Swimming pool pumps are responsible for circulating the water in your pool, and they typically run on a timer. The size of your pool, the type of pump you have, and how often you use your pool will determine how often you need to run your pump.

The process of a swimming pool pump is quite simple and we have broken it down into easy steps:

Suck The Water

You can think of your pool pump as a giant straw. It is constantly sucking water from one end and spitting it out the other. The first step in understanding how do swimming pool pumps work is to look at how it draws water into the system.

The vast majority of residential swimming pools have what is called a suction-side pool pump. This type of pump is connected to the skimmer basket and main drain of your pool.

As water splashes around in your pool, small particles of dirt and debris are pulled into these drains. The suction created by the moving water causes these particles to be drawn up into the pump basket where they are trapped.

The pump basket works like a strainer and is typically clear so you can see when it needs to be emptied. Some pool pumps have a float switch that will automatically turn the pump off when the basket is full, while others will require you to manually turn the pump off.

Filter The Water

Once the water has been drawn into the pump, it then passes through the filter. The type of filter you have will determine how effective it is at removing dirt and debris from the water.

The most common type of pool filter is a sand filter. Sand filters use a bed of sand to trap dirt and debris as the water passes through. The sand needs to be replaced every few years, but they are very effective at keeping your pool water clean.

Other types of filters include cartridge filters and diatomaceous earth (DE) filters. Cartridge filters use a pleated paper element to trap dirt and debris, while DE filters use a fine powder to do the same thing.

Both of these types of filters require less maintenance than sand filters, but they are also more expensive.

Circulate The Water

Once the water has been filtered, it is then pumped back into the pool. This is where the second half of the equation comes in – how does a swimming pool pump circulate the water?

As the water is pumped back into the pool, it passes through what is called a jet return. The jet return is simply a hole in the side of the pool where the water comes out.

The force of the water coming out of the jet return creates a current in the pool. This current circulates the water around the pool, which helps to evenly distribute chemicals and keep the water clean.


The cycle then starts all over again as the pump continues to draw water from the skimmer and main drain. The only time this cycle is interrupted is when you turn the pump off or when the basket is full.

Swimming pool pumps are a vital part of keeping your pool clean and safe to swim in. Without a pump, the water would quickly become stagnant and dirty.

Do You Run Pool Pump While Swimming?

Most people believe that you should not run the pool pump while swimming. The main reason for this is that it can be dangerous to have the suction end of the pump near swimmers.

If the suction end of the pump is left open, it can create a strong current that can pull swimmers into the pump and injure them. For this reason, it is important to make sure that the suction end of the pump is always covered when the pump is running.

Another reason why you should not run the pool pump while swimming is that it can be very loud. The noise from the pump can be disturbing and can ruin the relaxation of swimming.

Final Words

Now that you know how swimming pool pumps work, you can see why they are so important. Without a pump, your pool would quickly become dirty and dangerous to swim in. Remember to always keep the suction end of the pump covered and to never run the pool pump while swimming. Doing so will help to keep your pool clean and safe for everyone to enjoy.
