What is the minimum turnover time for spas?

The minimum turnover time for spas is 30 minutes. This means that the entire volume of water in the spa should be filtered and circulated at least once every half hour. This relatively short turnover time is crucial for maintaining water quality and safety in spas, which typically operate at higher temperatures and have a smaller volume of water compared to pools.

Higher temperatures and bather loads in spas can lead to quicker degradation of water quality; hence, frequent turnover is necessary to ensure effective chemical distribution and contaminants removal. This standard helps prevent the buildup of contaminants, reduces the risk of waterborne illnesses, and overall maintains a safe and pleasant environment for spa users.
