Frequently Asked Questions

1. How long does it take to fill a hot tub?

The time it takes to fill a hot tub depends on its size and the water pressure available. On average, filling a standard-sized hot tub can take anywhere from 1 to 3 hours. Larger hot tubs may take longer to fill compared to smaller ones. If you’re concerned about water consumption, consider using a garden hose with a higher flow rate or filling the tub during off-peak hours when water pressure is higher.

2. Can I use hot water from my home’s water heater to fill the hot tub?

Yes, you can use hot water from your home’s water heater to fill your hot tub. However, there are a few things to keep in mind. The water temperature should not be too hot. The maximum temperature of the hot water from your water heater is usually around 140 degrees Fahrenheit. If the water is too hot, it could damage the hot tub’s plumbing or heater. You should avoid using the hot water drain from your water heater. The hot water drain is located at the bottom of the water heater, and it can contain sediment and other debris. This debris could clog the hot tub’s filters or jets.

3. What are the risks of using saltwater or pool water to fill the hot tub?

Using saltwater or pool water to fill a hot tub can introduce several risks and challenges that may negatively impact the hot tub’s performance and longevity. One significant concern is the potential for corrosion due to the presence of dissolved salts in saltwater. These salts can accelerate the deterioration of metal components within the hot tub, such as jets, heaters, and pump seals. Moreover, pool water often contains chlorine or other chemicals that are not specifically designed for use in hot tubs. When pool water is added directly to the hot tub, it can disrupt the water’s chemical balance, causing issues with water clarity and sanitation. Improper chemical levels can create an environment that is either too acidic or too alkaline, leading to discomfort for hot tub users and potentially harming the hot tub’s interior surfaces.

4. How high to fill a hot tub?

The water level in a hot tub should be high enough to cover all the jets but should not overflow when people are using it. Usually, hot tub manufacturers recommend filling the water to about 2 to 3 inches above the highest jets. This level ensures proper functionality of the jets and provides a comfortable experience for the users.

5. How often do you have to fill a hot tub?

The frequency of refilling a hot tub depends on how often it’s used, the size of the tub, and the care taken to maintain water quality. On average, hot tub owners may need to drain and refill their tubs every 3 to 4 months. However, with regular maintenance, including proper chemical treatment, regular filtration, and covering the tub when not in use, the water can last longer before needing replacement.

6. How much water does it take to fill a hot tub?

The amount of water required to fill a hot tub varies based on its size and shape. On average, most hot tubs have a capacity of 250 to 500 gallons (946 to 1893 liters). Larger hot tubs can hold up to 800 gallons (3028 liters) or more. If you want to know the precise amount, check the manufacturer’s specifications or the owner’s manual for your specific hot tub model.
