When to Drain and Refill Your Hot Tub

Most hot tubs need fresh water about every 3 to 4 months. Heavy use, frequent guests, or mineral-heavy water can require shorter intervals.

• Cloudy water returns quickly after correction. Repeating cloudiness often signals water that is beyond easy stabilization.
• Foam or odor persists despite balancing. Persistent symptoms can mean dissolved solids and organics are too high.
• Sanitizer demand stays unusually high. If chlorine or bromine is consumed too fast, a water reset is often the better fix.
• Water has been in service for several months. Routine drain-and-refill intervals keep water easier to balance and maintain.
