Simply speaking, swimming pools are just big basins of water, and regardless of shape and size, they all generally work in the same way. They use a combination of filtration and chemicals to continually clean a large volume of water.
In the most basic terms the way a pool works is, water is pumped in a continual cycle, from the pool (starting at the main drain), through the filter, heater, chemical treatment system (i.e. chlorinator or FROG® Mineral System), and back into the pool again. This continuous cycling of the water through a filter and chemical treatment system helps keep the water in the pool free of dirt, debris and bacteria. Some pools also include a heater to keep the water at a desirable temperature.
A swimming pool typically needs these ten major components to function continuously:
- The pool
- The skimmer(s) (designed to filter large debris from the water)
- The circulation pump (circulates the water)
- The water filter (removes small particles from the water)
- The heater (regulates water temperature)
- The chemical feeder (sanitizes the water)
- Drains (removes the water)
- Returns (returns circulated water)
- Plumbing (connects all of the above)
- Time Clock (regulates the run time of the pump)
