A full drain and refill every 3 months is recommended, regardless of use. Without it you risk cloudy water, uncomfortable bathing and potential long-term damage to your equipment.
Why drain and refill matters
Over time, hot tub water accumulates body oils, lotions, debris and leftover chemicals, even with routine filtering. These impurities affect water clarity, chemical balance, and can cause skin irritation or foul odours.
Don't forget your swim spa
We also offer a full swim spa drain and refill in Marlow, including cleaning, equipment inspection and chemical balancing. It is ideal for large swim spa units and is typically needed every 6 months.
