In order to make the correct chemical adjustments and to ensure properly-sized pool equipment (primarily the pump and filter) as well as properly-sized plumbing pipe diameters and schematics, you must first know the approximate - but close - number of gallons of water in your swimming pool. While there are pre-calculated charts available, more times than not the listed gallons within these charts are incorrect because of certain variables and measurements that are omitted from these pre-calculated charts.
Any discussion about chemical adjustments requires that you know the approximate gallons of water in your pool; this information is mandatory if chemical adjustments are to be made correctly.
Any discussion about equipment sizing requires that you know the approximate gallons of water in your pool; this information is mandatory to ensure that the pump and filter are collectively able to circulate, filter, clean and help clarify the water in your pool.
Any discussion about plumbing sizing and schematics requires that you know the approximate gallons of water in your pool; this information is mandatory for proper velocity of water movement to and through the pipes, which affects the potential for entrapment and drowning, primarily at suction fixtures such as the main drain and skimmers.
A properly chemically-treated, equipped, and plumbed pool is a safe pool.
It all starts with an understanding of the approximate - but close - number of gallons of water in your swimming pool.
There are calculations for every shape and depth of pool, to include:
- Rectangle pools
- L-shaped pools
- Lazy-L pools
- Roman-End pools
- Gothic pools
- Grecian pools
- Square pools
- Kidney pools
- Figure-8 pools
- Free-Form pools
- Oval pools
- Round pools
- Your pool
You can read the Pool Manual for the exact calculation, calculation parameters, and additional considerations to determine the gallons of water in your pool. Not only will we provide you with the calculations, but we will also detail why the "universal calculations" sometimes will not work for your pool.
