What is the minimum turnover rate for residential swimming pools?

The minimum turnover rate for residential swimming pools is established to ensure that all the water in the pool is adequately filtered and sanitized at least once every four hours. This time frame is crucial for maintaining water quality, preventing the growth of harmful bacteria and algae, and ensuring the health and safety of swimmers. A four-hour turnover rate allows the filtration system to efficiently process the volume of water, removing impurities and maintaining clarity. By adhering to this standard, pool operators can help ensure that the swimming environment remains safe and pleasant for users. This guideline is part of best practices in pool management and is often referenced in state regulations.
