The 7 Different Parts Of A Pool And What They Do

Parts Of A Pool

When you look at the big picture, swimming pools are just simple. It’s just a big basin with water. But during summertime, pools are convenient and seem to be one of the efficient inventions of humans.

What are the parts of a pool called? There are seven parts to a swimming pool. These are the skimmer, main drain, suction line, pump, filter, return lines and return jets.

As you read on, you’ll learn further about the parts mentioned above of a swimming pool. I will also list the importance of knowing the different parts of a pool.

Plus, a glossary of common swimming pools that you might find helpful too. It will also tackle the standard size and design when making a pool.

List Of The Suction Side Of The Swimming Pool

The suction side is responsible for drawing water up out of the pool going to the pump. It’s also an essential part of the pool as it begins the circulation process. Here is the list that belongs to the suction side of the pool.


Water from the pool’s surface is drawn into the filtration system by the skimmer. You can find it on the side of the pool.

Your pool’s first line of defense is in terms of clarity and cleanliness since it helps to remove leaves, insects, and pollen from the water. Automatic pool cleaners are also included in this protection system.

The trash is trapped in the skimmer basket after passing through a flapping door known as a weir. To keep your filtration system running well, you’ll need to empty the skimmer basket regularly.

The Suction Lines

The suction lines travel from the skimmer to the pump system and are either flexible or stiff PVC pipes. Suction lines can be either above ground or underground, depending on the style of pool you have.

Aside from that, suction lines might burst, producing system difficulties. The leak is easier to identify and rectify if the suction lines are above ground. Also, it’s harder to search if it’s below ground and will cost you more money for a repair.

The Main Drain

They say that there are two types of outlets in most pools. These are the skimmers and the main drain. You can find the main drain at the bottom of the pool and the pump suctions water and dirt or tiny matter through the drain.

But, if the drain holes are blocked, they will be unable to do their work correctly. Then the pressure will build up in the pump, producing issues.

When the main drain was covered, one issue was that the suction grew so powerful that swimmers, including children, became trapped and drowned. But today’s pool included stricter safety guides, especially to the main drains. 

Lists Of The Filtration System

The filtration system is essential to the pool’s operation. Because it helps circulate the water through the steps required to keep it clean, usable, and warm. Here is the part of the pool included in the filtration system.

The Pump

The suction lines lead to the pump, which functions similarly to human hearts. The pump circulates water throughout the pool system and is essential to its operation.

It transports water through the filter, heater, and chlorinator to ensure that it is clean, warm, and has the proper chemical mix.

There are different types of pumps that you can buy in the market, but determine the flow rate and the head for the right pump size.

  • Flow Rate – refers to the amount of water flowing at a given time and is measured in gallons per minute (GPM).

  • Head – The number of bends in the pipe your water must go through, the size of the pipes, and the distance the water must travel are all factors that affect flow resistance. In addition, feet of resistance or feet of the head are used to measure this.

The cost of the pump is determined by the pump you choose. A new pump can cost up to $800. Pumps should be replaced every eight to fifteen years; watch for typical symptoms that you may need to replace along the way.

The Pool Filter

When it comes to pool cleaning, chlorine only accomplishes half the job. The rest is taken care of by the pool filter. The filter captures small bits of dirt and bacteria, and the water filters back into the pool once it is clean. Listed below are the different types:

  • Sand Filter
  • Cartridge Filter
  • Diatomaceous Earth Filter

Lists Of The Pressure Side Of The Pool

The pressure side is the one that pushes the filtered water back into the pool.

Return Lines

There are two to three return lines, but it depends on the pool’s size. Water is carried from the circulation system to the return jets via return lines.

Return Jets

The water will go back into the pool via the return jets. The water circulation is controlled by moveable return jets.

Pointing them down improves chemical and temperature dispersion as well as filtration. Read my return jets troubleshooting guide if you’re experiencing issues with them.

Importance Of Knowing The Parts Of A Pool

Swimming pools come in a wide range of sizes, shapes, and designs. That’s why it’s crucial to know the parts that make up your pool so you can properly maintain it.

A well-maintained pool can keep functioning for the rest of its life. Purchasing, installing, or constructing a pool is a substantial financial investment. So, it would help if you learned as much as possible about your pool equipment and setup before purchasing it.

History Of A Swimming Pool

Swimming as a competitive sport dates back to 2500 B.C. in Egypt. The Romans were the first to invent swimming pools in the first century B.C. Swimming was an element of a young boy’s education in ancient Rome and Greece.

Many of the Roman pools were also heated with water channeled from natural springs via a pipe.

The wealthy society flocked to the glorious bathhouses built with marble and costly gilding. However, the bulk of people continued to swim in lakes and rivers.

These swimming pools were the forerunners of today’s pools. Many people in Europe avoided creating swimming pools out of concern that diseased swimmers could spread diseases.

In 1837, Europeans created the first swimming club in London, which had six indoor pools. Swimming pools did not gain popularity until 1896 when the first modern Olympic games were held.

The Raw Materials Used

PVC plastic, galvanized steel or metal, fiberglass, concrete, and polyurethane foam are raw materials used to make swimming pools.

Steel bars that are adequate for strengthening a concrete pool range in diameter from 0.38 in (0.97 cm) to 0.75 in (1.9 cm). These value requirements depend on the design.

All pool piping must be made of 40 PVC or comparable material and stamped with the American Society for Testing and Materials (ASTM). Plastic or comparable materials are commonly used for liners.

Its Design

The range of swimming pool designs reflects the consumer’s particular spatial and economic considerations. Concrete pools are the most adaptable, allowing for any shape or layout.

The pool’s layout, which includes shape, elevation, and size, is depicted in design drawings. An engineer can help with soil and structural studies and determine the best location and design for a pool installation.

To ensure a structurally stable pool, soil study is undertaken on all surfaces before installation.

Different Types Of A Swimming Pool

Swimming pools, like everything else, exist in a variety of styles, forms, sizes, and shapes. Budget, lot size, local ordinances, and material availability will all influence the type of pool you eventually want to build on your property.

Before taking the plunge, consider what type of swimming pool would be best for you and your family. Take a look around at some possible options that you can choose.

1. The Above-Ground Swimming Pool

Above-ground pools have frequently served as a symbol of affordable pool ownership for the lower middle classes. An example of it is The Heck family on “The Middle.”

For starters, among the reasons above-ground pools become more prevalent in a down economy is their lower cost.

Other reasons to choose an above-ground pool include:

  • Due to its portability, you can take the pool with you if you move.
  • Certain types of land, such as rocky places, are easier to work with.
  • An above-ground pool can have a deck installed later and yet be less expensive than an in-ground model.
  • Allows homeowners to get their pool feet wet in a less expensive, more portable style of a swimming pool.

2. The Architectural Pool

An architectural pool must have structure, clear lines, and it typically mirrors the design of the house and utilizes the same materials for a unified effect. An architect usually designs a geometric, elegant architectural pool.

3. The Family Pool Or The Recreational Pool

They’re similar to a water park but in a smaller size and with fewer swimmers. Recreational pools are known for their spectacular water features, sophisticated slides, caves, tunnels, rocks, and overall all-ages appeal.

While they are generally large enough, don’t expect to work in some laps. At least not while the kids are splashing around in these tiny water parks.

4. The Infinity Pool

These types of pools are also known as vanishing edge pools, negative edge pools, and more. Infinity pools are always custom-built and designed to accentuate a view.

When done correctly, an infinity pool creates the illusion of a sheet of water pouring from the edge of the property, similar to a waterfall, even if you can’t see or hear falling water. Also, infinity pools are among the most expensive residential pools.

5. The Indoor Swimming Pool

An indoor swimming pool is self-explanatory—inside. Indoor pools are often simple, geometric shapes for swimming or training all year, particularly in chilly climates.

6. Kiddie Swimming Pool

The easy-to-find, disposable inflatable kiddie pool is at the bottom of the scale of affordable pools.

You might acquire one for 75% off at the end of the season that you can use the following year if you have the storage room and the PVC type. Inflatable pools have been in the industry since the 1940s.

Making pool ownership possible for everyone with a porch or plot of land. Or even on a sidewalk or in a driveway. Kiddie pools are a component of the American Dream that is both achievable and affordable.

You make sure to drain the pool after using it and maintain an eye on the kids at all times.

7. The Lap Swimming Pool

It is a swimming pool designed for fitness and health purposes. Lap pools are often long and narrow, reaching lengths of more than 50 feet. It is usually rectangular in shape and can be created on long, narrow sites.

8. Natural Swimming Pool

Natural swimming pools, also known as swimming ponds in Europe, originated in the 1980s. It is self-cleaning pools that mix with swimming sections and water gardens.

Like any other in-ground, private swimming pool, natural pools can be created in a freeform, rustic style with stones and waterfalls. Or they can be modern or architectural—sleek and attractive.

The majority of natural pools consist of rubber or reinforced polyethylene linings. A distinct “regeneration” zone within the pool is outfitted with aquatic vegetation and an organic cleaning system.

Water is circulated through the regeneration zone by skimmers and pumps, which draw it across a wall of pebbles or loose gravels. Friendly bacteria adheres to the wall and acts as an extra-biological filter.

9. Olympic-Sized Swimming Pool

Swimming is among the prevalent Olympic sports worldwide. That’s why it’s no surprise that aspiring Olympians are swept up in the excitement of the significant event and desire their own Olympic-sized swimming pool.

10. The Plunge Swimming Pool

It’s a small, cold-water pool that’s been utilized in Chinese medicine for hundreds of years. It’s popular with the Ancient Romans.

Many swimmers and athletes believe that jumping into a chilly pool after a workout, sauna, or spa session offers therapeutic benefits.

11. A Saltwater Swimming Pool

Saltwater pools became popular in Australia and New Zealand for many years before spreading to other continents. They are not a design or style of pool.

However, you have already built a saltwater chlorinator or generator into your pool. The generator can be installed either during or after the pool construction procedure.

You can also add chlorinator to an above-ground pool, as long as it is designed explicitly for above-ground swimming pools.

12. A Spool

A spool is formed by combining the phrases spa and pool. Pool builders have witnessed an increase in homeowner requests for custom-built spools since the recession.

Many people downsized, and their smaller lots aren’t large enough to accommodate a larger pool. Some people use it for relaxation and entertainment, while others use it as a lukewarm-to-cold mini pool to soak in and cool off on hot days. Plus, the fact that it’s free.

The Purpose Of Building A Swimming Pool

  • Recreational – Pools must feature a shallow and, in certain situations, a deep end for recreational purposes. The shallow end is suitable for children, while the deep end is suitable for older or more experienced swimmers.

    It is essential since you may expect people of all ages to use the pool. To fulfill most pool purposes, a depth of fewer than six feet is advisable.

  • Regular Exercise – For swimming laps, the pool should be rectangular. The proposed minimum length is 30 feet to allow for lap swimming and exercising. The swim lane is essential, but so are the depth and other elements.

  • Competitive And Athletic Swimmers’ Use – Pool depths should be greater than your height for competitive and athletic swimmers. It would be best if you also had a pool that allows you to practice complete strokes.

The Space For Building

Not all pool requirements are the same, and not all backyards have the same size. As a result, the amount of space you have in your backyard will determine the size of the pool you can install.

As well as any other design features you want to have. Nonetheless, not all homes have larger spaces to support a variety of pool sizes.

Budget Or Financial Stability

When assessing the size of your pool construction, long-term budgeting is essential. Pools are expensive to install, operate, and maintain, so there’s no magic number for determining how to plan for long-term pool maintenance.

It’s best to base your costs on the usage, location, and maintenance schedule agreed with your constructor. Other fees to consider include general maintenance, covers, cleaning, and other services.

The size of your pool influences every aspect of the pool’s requirements, so you should consider what pool size or design will work best for your budget.

Many finance companies specialize in outdoor living projects. Meaning they can help you reduce the costs for your pool project.

This type of financing can provide you, your desired pool. And offer free pool maintenance and other pool-related expenses in the long run.

Thinking Of The Right Size Swimming Pool

Choosing the ideal swimming pool size and shape for your family may be more difficult. You will have to think about a lot of things that for sure will overwhelm you. It is where a professional swimming pool installer comes into the picture.

Professional swimming pool installers can assist you in exploring your swimming pool model options. They will present you with options based on your needs and determine the best pool size to meet all of the considerations.

How To Design A Swimming Pool

Depending on the desired style and maintenance, the area around the pool can be designed with stone decking or simple wood. It’s either natural or synthetic wood or natural or tiled stone.

You can also use stones to build a low border wall around the entire pool. Umbrellas and various garden furniture are also a good addition for shade and some enjoyment.

An Additional Equipment For Swimming Pool

Do you have some spare cash? Want to make pool maintenance more accessible and more enjoyable? You can supplement the lineup with a couple of extra pieces of equipment.

A Pool Heater

No, it is not a necessary component of a swimming pool. It does not affect circulation or filtration. It does, however, make your pool more comfortable and may even extend your pool season.

It is available for both above-ground and inground swimming pools. 

You can choose from these heating methods: Natural gas, propane, electricity, and even solar are options.

A Chemical Feeder

This valuable piece of equipment makes sanitizing your pool a breeze. Fill it with whatever sanitizer the feeder is designed to use.

Like the chlorine, bromine, or a mineral cartridge—hook it up, and you won’t have to worry about sanitizer for a while. This is the final piece of filtration equipment in your system.

If you use both a pool heater and a chemical feeder, make sure you connect them to your filtration system in the correct order. Water should pass through them in the following order:

  • Pump
  • Filter
  • Heater
  • Chemical Feeder

Benefits Of Swimming

There are lots of benefits if swimming, may it be in a pool or on a beach. Swimming, as they say, is one good all-round activity because:

  • It helps keep your heart rate up but takes the impact of the stress off the body
  • helps maintain a healthy weight, lungs, and a healthy heart
  • It helps tone the muscles and builds up strength
  • Provides an overall body workout
  • Alleviate stress
  • It helps improve balance, coordination, and posture.
  • Provides an excellent low-impact therapy from injuries


In general, there are seven major parts of a swimming pool you need to know. The mentioned parts of a pool are essential, especially if you’re planning to build one.

However, if you can’t learn or memorize it in time, you can seek help from a professional. To have the perfect swimming pools that you desire for your family.
