The article explains the importance and functioning of pool skimmers in a home swimming pool filtration system. Skimmers are vital for filtering out larger debris, such as leaves and dirt, before the pool water runs through the rest of the filtration system. They ensure the pool remains clean and safe for swimming. There are several types of skimmers including inground pool skimmers, mounted skimmers, floating skimmers, robotic skimmers, solar skimmers, hot tub and spa skimmers, and hand pool skimmers. All skimmers have similar components such as a mouth, weir, skimmer basket, equalizer line, suction line, and lid. Regular maintenance and cleaning of the skimmers are necessary to prevent strain on the pump and to prolong its lifespan. It is recommended to empty pool skimmers daily and more frequently during seasons with falling leaves. The article also provides steps to winterize the skimmer lines when closing the pool for the season.
