How Long Does it Take to Fill a Hot Tub?


In the realm of luxury and relaxation, few experiences can rival the soothing embrace of a hot tub. If you’re the proud owner of a hot tub, you’re undoubtedly no stranger to the serene comfort it provides. However, to ensure that your hydrotherapy haven remains pristine and inviting, it’s essential to undertake routine maintenance, including draining and filling your hot tub. But how much time should you set aside for this process? In this guide, we’ll delve into the details of draining and filling your Wellis hot tub, helping you maximize your relaxation time.

Time to Drain and Fill a Hot Tub

The duration required to drain and fill your hot tub can vary depending on several factors, spa water itself. The specific model of your hot tub plays a crucial role, as the water-holding capacity differs from one model to another. On average, you can expect the draining process to take approximately one to two hours. However, this timeframe may fluctuate based on factors such as water pressure in your area.

When it comes to filling your hot tub, you should allocate around two to three hours. This timeframe accounts for the gradual flow of water to ensure proper filling without overwhelming the spa’s systems. Keep in mind that precise refill timing is essential, as you wouldn’t want to miss out on any valuable soaking and relaxation time.

How to Drain Your Hot Tub


Before initiating the draining process, it’s advisable to take certain preparatory measures. The day before you intend to drain your Wellis hot tub, consider using a high-quality hot tub cleaner. Add this cleaner to the hot tub water and activate your spa’s jet system at its highest setting for approximately half an hour. This step ensures that the cleaner thoroughly circulates throughout the spa, reaching all corners of the circulation system.

Cleaning Your Spa

While draining and filling your hot tub, seize the opportunity to clean every nook and cranny of your spa. This includes the filters and skimmer baskets. Proper maintenance not only ensures the longevity and power of your hot tub but also contributes to a hygienic and enjoyable experience.

The Draining Process

When the day arrives to commence the draining process, rest assured that every Wellis Hot Tub is equipped with a convenient drain valve cover. While it’s not mandatory, using a submersible pump can significantly expedite the process, saving you valuable time.

As the water begins to drain, seize the opportunity to rinse down the sides of your hot tubs to eliminate any residue or stuck-on debris. Towels can be employed to soak up any remaining water in the seats and at the bottom. Alternatively, consider using a wet/dry vacuum for a more efficient water removal process.

How to Fill Your Hot Tub

Once your hot tub is drained, it’s time to embark on the filling process. To ensure optimal results, remove your air filter cartridges from the hot tub. Place the water hose in the designated area to facilitate water intake through the system.

Wellis offers a charcoal prefilter that can be attached to your own hose pipe, effectively removing contaminants from the water. Additionally, there’s an option for an extra water-softening prefilter, which enhances water quality for your luxury hot tub.

While filling your hot tub, monitor the water level closely, ensuring it reaches the minimum water level line specified for your spa. Maintaining the correct water level is crucial to prevent any damage to your Wellis Hot Tub system. Once the water is at the appropriate level, commence testing to achieve the optimal temperature and chemical balance.

Timeline Considerations to Drain and Fill a Hot Tub

If you’re planning to host a grand hot tub gathering and wish to ensure fresh and clean water for your guests, strategic timing is essential. Begin the process mid-week if your event is scheduled for the weekend. This timeline allows for the effective action of the system purge cleaner. You can drain the hot tub overnight, and by the next morning, you can fill it and balance the chemicals, preparing the water for a weekend of relaxation and enjoyment.

In conclusion, while the process of draining and filling your hot tub may seem daunting at first, it becomes a straightforward and efficient routine with practice. By following these guidelines and taking time to plan ahead, you can ensure that your hot tub remains a haven of luxury and relaxation, always ready to provide you with the ultimate hydrotherapy experience. Happy soaking!
