avoiding costly errors when maintaining your hot tub spa

Hot tub spas can provide a delightful escape from the daily grind, but maintaining one requires diligence and knowledge. Common mistakes can lead to costly repairs and diminished enjoyment. In 2026, let us explore how to avoid those pitfalls and keep your spa in optimal condition.

Neglecting Regular Water Testing

Water chemistry is crucial in ensuring your hot tub spa is both safe and comfortable. A common mistake is neglecting regular water testing. You should test the water at least twice a week, using test strips or a liquid kit. This helps you maintain balanced pH levels, alkalinity, and sanitiser levels. If the water is too acidic or alkaline, it can damage your hot tub’s components and surfaces. Regular testing prevents these issues and enhances your bathing experience.

Ignoring Filter Maintenance

Another costly error is ignoring the maintenance of your filter. The filter plays a vital role in keeping the water clean and free of debris. Depending on usage, it should be cleaned every four to six weeks. If you fail to do this, the filter will become clogged, leading to reduced water circulation and increased strain on the pump. Replace your filter according to the manufacturer's recommendations, typically every 12 to 24 months, to ensure optimal performance.

Overlooking the Importance of Draining

Water in your hot tub should not be left indefinitely. A common mistake is failing to drain and refill the hot tub every three to four months. Over time, dissolved minerals and contaminants accumulate, affecting water quality. Regularly draining your spa not only refreshes the water but also allows you to clean the shell properly. Ensure you follow the manufacturer's guidelines on draining procedures to avoid damaging any components.

Inconsistent Temperature Settings

A hot tub spa works best when the water temperature is consistent. Many users make the mistake of fluctuating the temperature frequently. This can place stress on the heating system and lead to malfunction. Set your desired temperature, typically between 37°C to 39°C, and leave it there. If you plan to be away for an extended period, consider lowering the temperature rather than turning it off completely; this helps maintain system efficiency.

Failing to Clean the Spa Cover

The hot tub cover is essential in keeping the water clean and maintaining temperature. However, it is often overlooked in maintenance routines. A dirty cover can harbour mould and mildew, which not only smells unpleasant but can also transfer into the water. Clean your cover monthly with a mild detergent, ensuring to rinse thoroughly. Additionally, apply a protective conditioner every few months to prolong its life and effectiveness.

Using Incorrect Chemicals

Using the wrong chemicals is another common error that can lead to severe damage. Always use spa-specific chemicals suited for your hot tub. Avoid household cleaners, as these can cause foaming and damage to the equipment. Read labels carefully and follow the recommended dosages. Incorrect chemical levels can lead to skin irritations and compromise the integrity of your hot tub.

Neglecting the Surrounding Area

Lastly, do not forget to maintain the area around your hot tub. A cluttered or dirty space can introduce debris into the water. Regularly sweep the area free of leaves and dirt. Consider installing a barrier to prevent plants from growing too close to your hot tub. By maintaining the surrounding area, you will significantly reduce the amount of debris that enters the water, ultimately leading to less cleaning and better water quality.
