In-ground filters are made of fiberglass and polyvinyl chloride, which provide a reasonable design, good looks, and durability. The in-ground filter does not need a machine house, which saves construction costs, allows for convenient operation, and reduces maintenance costs. Multi-use in-ground sand filters assemble a complete set of filtration configurations with high filtering capacity and the ability to perform backwashing. According to swimming pool specifications and standards, it is the best choice for large and commercial swimming pools.
