Dallas Cool Pools makes sure you understand the building process. 

Want a head start on your conversation with our design expert? Read up on some key terms below.But don’t worry. We’ll never use confusing jargon without bringing you into the know!

The upper section of the vertical wall of a gunite pool or spa. A “raised beam” is one that extends above ground level.

An electrical unit that generates air pressure to provide the spa jets with bubbles.

Cantilever Edge
A pool deck of a poured or sprayed material that extends slightly beyond the edge of the pool negating the need for traditional coping.

Cartridge Filter 
A filtration system that uses a fine mesh material to remove suspended contaminants from the water. This type of filter requires a 30 minute cleaning with a garden hose six to ten times per year.

A unit that holds chlorine tablets and automatically treats the water.

Material that covers the first nine to twelve inches of horizontal surface at the pool’s edge. It can be brick, flagstone, concrete, or one of many natural or man-made materials.

Patio that is attached to the pool itself. Typical materials and finishes include brushed concrete, spraycrete, cool deck, sundek, flagstone, and pea gravel. The deck often accounts for 20 to 30% of a pool budget.

DE Filter Filtration
System that uses a layer of fine powder (diatomaceous earth) to remove contaminants from the water. This type of filter requires a ten minute backwashing process about once a month that is accomplished by adjusting the valves. The DE powder is relatively inexpensive but must be replaced after each back washing.

Gas Heater
Spas and heated pools require a large heater to quickly heat the large volume of water necessary. These are fueled by propane or natural gas and are often the most expensive piece of equipment.

A type of concrete that is applied with a sprayer to form the pool shell. It can also be used to form slides, waterfalls, pads, and other features.

In-Floor Cleaning System
A system of pop-up jets in the floor of a pool that direct settled debris to an active drain for removal.

Lap Pool
A long, narrow pool, usually about four feet deep for swimming laps.

A smooth cement coating that seals a gunite pool shell. The color of the plaster determines the apparent color of the water.
White = Light Blue
Grey = Deep Blue
Green = Blue/Green
Brown = Emerald Green Water

Salt System
A system that uses electricity to disinfect water with chemicals extracted from salt.

Sand Filter
A filtration system that removes contaminants by forcing the water through a vessel of sand. With no need for replacement chemicals, these systems only require monthly backwashing!

Sports Pool
Types of pools that accommodate a net or goals for games such as volleyball, basketball, or water-polo. They are usually 3-4 feet deep at the ends and 4.5 – 5 feet deep in the middle.

Any vessel that holds hot water for soaking. Most popular spas are an integral part of the gunite pool, have multiple jets, and use the same circulation system as the pool. Different from hot tubs which usually refer to wooden vessels.
*Extra credit: Jacuzzi is a brand of spa equipment, not a spa or hot tub!

Sweeper System
A device that uses water pressure or suction to mechanically remove debris from the floor and walls of a pool.

Swim Spa
Sometimes called a “Spool”, swim spas are usually about eight feet by twelve feet and have a large jet capable of generating a current to swim against.

The material which lines the inside rim of the pool or spa at the waterline, and extends from just under the coping edge to six inches beneath it.
Tile is generally made of non-porous materials like ceramic, porcelain, flagstone or marble, to discourage floating contaminants from collecting. These can include ceramic tile, porcelain tile, flagstone, or marble.
