The standard turnover rate required in codes for spas typically should not exceed how many minutes?

The standard turnover rate required in codes for spas is commonly set at a maximum of 30 minutes. This means that the water in the spa should be completely filtered and recirculated within this timeframe to ensure proper sanitation and water quality.

Achieving a 30-minute turnover rate is crucial because spas tend to operate at higher temperatures and lower water volumes compared to swimming pools, which can lead to a quicker accumulation of contaminants. A shorter turnover rate helps to ensure that disinfectants remain effective and that the water stays safe for bathers. Maintaining this rate minimizes the risk of waterborne illnesses and ensures a pleasant experience for users.

If the turnover time exceeds 30 minutes, it may indicate that the filtration system is inadequate or that maintenance is not being performed properly, which could lead to health risks and degrade the quality of the spa environment.
