Understanding the Anatomy of a Swimming Pool
A Breakdown by Foley Pools
Building or maintaining a pool can feel overwhelming if you don’t understand the basic components that make it function. Whether you’re considering a new custom pool or looking to maintain your current one, knowing the "anatomy" of a swimming pool can help you better appreciate its design and operation.
At Foley Pools, we pride ourselves on educating homeowners about the essential elements that keep their pools in perfect condition. Here’s an overview of the critical components that work together to create a functional and beautiful swimming pool.
The Shell: Foundation of the Pool
The pool’s shell is its structure—the form that holds the water and gives your pool its shape. Most custom pools use a durable gunite or shotcrete base, ensuring longevity and strength. The shell is reinforced with steel rebar and coated with plaster or aggregate to provide a smooth finish.
Custom Options
Whether you choose freeform, geometric, or straight-line designs, the shell determines your pool’s visual appeal and functionality.
Circulation System: The Heart of Your Pool
Heating and Cooling Systems: Comfort Year-Round
Special Features: Enhancing the Experience
Decking and Coping: Framing Your Pool
Pool Plumbing: Behind-the-Scenes Power
The circulation system keeps your pool water clean and healthy by continuously moving and filtering it.
Pool Pump
Often referred to as the heart of the pool, the pump pulls water from the pool, sends it through the filter, and returns it to the pool. Modern variable-speed pumps are energy-efficient and help reduce operational costs.
Pool Filters
Filters remove dirt, debris, and impurities from the water. There are three main types:
DE (Diatomaceous Earth) Filters: Superior filtration that traps the smallest particles
Cartridge Filters: Easy to clean and ideal for smaller pools
Sand Filters: Low-maintenance and effective for larger pools
Skimmers & Returns
Skimmers pull in surface debris (like leaves), while return jets push clean, filtered water back into the pool, ensuring even circulation.
Water Chemistry: Keeping the Pool Clean and Safe
Maintaining proper water balance is essential to prevent algae, bacteria, and equipment corrosion. Here’s what you need to monitor:
Chlorine or Salt Systems
Chlorine keeps the water sanitized, while saltwater systems generate chlorine naturally for a gentler swimming experience.
pH Levels
Balanced pH keeps the water comfortable and protects pool surfaces.
Additional Treatments
Shocks, algaecides, and stabilizers help ensure water clarity and quality.
Proper water care prolongs the life of your pool and keeps it safe for swimmers.
Texas weather can be unpredictable, so adding a heating or cooling system ensures your pool stays comfortable throughout the seasons. Adding these systems allows you to maximize your pool’s usability year-round.
Pool Heaters
Gas heaters or heat pumps keep water warm in cooler months.
Chillers
For hot Texas summers, pool chillers cool the water, creating a refreshing escape.
Hidden from view, your pool’s plumbing system ensures water flows efficiently between the pump, filter, and features. Pipes, valves, and drains work together to manage water circulation and filtration. Proper plumbing ensures a seamless, worry-free pool experience.
Main Drain
Located at the bottom of the pool, the main drain helps remove debris and ensures balanced water circulation.
Overflow and Backwash Lines
These systems prevent overfilling and help maintain water levels.
