Q: How does a filtration system work?
A: First of all, pool water passes through a bottom drain or skimmer on its way to the pump. The pump then pushes the water towards a filter to remove impurities and debris. Next, the water passes through various conduits to be heated. Finally, the water is returned to the pool. Elements for keeping water optimal for swimming, such as chlorine dispensers, can be installed at the end of the filtration system to keep water clean for swimmers.
