What is the turnover time in the context of pool operation?

Turnover time refers to the duration it takes for the entire volume of water in a pool or spa to be circulated through the filtration system. This is a crucial aspect of pool operation because proper turnover ensures that the water is adequately filtered and sanitized, helping to maintain water quality and safety for swimmers.

A pool’s filtration system is designed to clean the water, removing contaminants, debris, and pathogens, and effective circulation is key to achieving this. Understanding turnover time helps operators schedule regular maintenance and assess whether the existing filtration system is adequate for the pool’s size and usage.

The other aspects mentioned in the choices, while related to pool operation, do not accurately define turnover time. The number of hours water circulates pertains to operational hours but does not specify it is equal to the whole pool volume; the total volume of water simply quantifies the pool without connecting it to filtration performance; and the duration of water filtration refers to the time water is processed for cleaning, but again, it does not encapsulate the complete turnover concept of circulating the entire water volume.
