When should the water in a public spa generally be replaced?

The recommended frequency for replacing water in a public spa is typically every 80 days. This timeline is based on a balance between maintaining water quality and minimizing the risk of illness. Regular water replacement helps ensure that contaminants, sanitizers, and disinfectants remain effective, contributing to a safe bathing environment.

The 80-day guideline is established by health regulations and best practices, considering factors like the volume of bather load, water temperature, and filtration effectiveness, all of which affect water quality. Over time, chemical imbalances and the accumulation of organic materials can compromise the water, making it essential to replace the water at this interval to maintain proper hygiene and usability.

It is important to be attentive to the specific conditions of each facility, as variations in usage might necessitate more frequent changes, but the 80-day mark serves as a general standard for routine maintenance.
