The flow of water throughout the pool has a major impact on the appearance as well as the “health” of the pool. The swimming pool pump filter is considered the “heart” of the swimming pool. All chemicals present in the pool water are pumped to all areas of the swimming pool, including through all the pool pipes, by the pool filtration system. In order to ensure proper operation and function, the filtration system should be cleaned by a professional. Inadequate water flow by the pool filtration system can result in the presence of algae, calcium build-up, and equipment and pool corrosion.
