Preparing To Fill the Hot Tub

Before filling your hot tub, it’s crucial to prepare properly. This ensures a smooth process and maintains the cleanliness and longevity of your tub. Here are the key steps to take beforehand:

  1. Clean the hot tub: Remove debris and use a hot tub cleaner product to sanitize the surfaces.
  2. Check water quality: Use test strips to test the pH and chlorine levels of the water. Adjust these levels as necessary to achieve balanced chemistry in your hot tub.
  3. Inspect equipment: Ensure the hot tub filter, jets, and heating system are in proper working condition.
  4. Gather supplies: Get a garden hose, submersible pump, hose filter (if needed), and any necessary chemicals or additives.

How Long Does It Take To Fill a Hot Tub?

The time it takes to fill a hot tub can vary depending on water pressure and the size of the tub. On average, it can take 1 to 4 hours to fill a hot tub.

Whether you’re using a garden hose or a submersible pump, filling a hot tub is a straightforward process.

Here’s a simplified guide to help you:

Filling With a Garden Hose Directly

Now that you’ve prepared your hot tub, it’s time to fill it up using a hose. Here’s a simplified guide to help you through the process:

  1. Connect the hose: Attach one end of the garden hose securely to a water source, such as an outdoor faucet.
  2. Attach a hose filter (if needed): If your water source has hard water or high mineral content, consider attaching a hose filter to prevent these minerals from entering your hot tub.
  3. Submerge the hose: Place the other end of the hose into the hot tub, ensuring it is fully submerged. This helps prevent air from entering the plumbing system.
  4. Open the water source: Turn on the water source slowly to allow a controlled flow into the tub. This prevents any sudden pressure changes that could damage the plumbing.
  5. Monitor the water level: Keep an eye on the water level as the tub fills. Avoid overfilling, as this can cause water to spill out when people enter the tub.
  6. Check for airlocks: While filling, check for any airlocks to ensure the water is flowing smoothly without any disruptions. If you notice air bubbles or sputtering, adjust the hose or gently tap the sides of the tub to release trapped air.
  7. Turn off the water: Once the hot tub reaches the desired water level, turn off the water source and remove the garden hose.

Filling With a Submersible Pump

Using a submersible pump can be a convenient option if you’re looking for an alternative method to fill your hot tub.

Here’s a step-by-step guide to help you through the process:

  1. Gather necessary supplies: Get a submersible pump, a power source, and any required chemicals or additives.
  2. Submerge the pump: Place the submersible pump into the hot tub, making sure it is fully submerged and positioned securely.
  3. Connect the pump: Connect the pump to a power source, following the manufacturer’s instructions. Ensure that the power cord is safely away from the water.
  4. Position the outlet hose: Attach the outlet hose to the pump’s discharge port. Position the other end of the hose either in the hot tub or connect it directly to the tub’s intake valve.
  5. Turn on the pump: Switch on the submersible pump and let it begin filling the hot tub. Keep an eye on the water level to prevent overfilling.
  6. Check for airlocks: As the tub fills, monitor for any airlocks or trapped air bubbles. Adjust the pump or gently tap the sides of the tub to release any trapped air.
  7. Turn off the pump and disconnect: Once the hot tub reaches the desired water level, switch off the pump and disconnect it from the power source. Remove the outlet hose from the tub.

Setting up the Hot Tub’s System

Setting up the system of your hot tub is crucial for its proper functioning.

Here’s a simplified step-by-step guide:

  1. Locate the control panel and familiarize yourself with its settings.
  2. Connect the hot tub to a power source and turn on the main power switch.
  3. Fill the hot tub following our previous guide on filling using a garden hose or submersible pump.
  4. Prime the circulation pump if your hot tub has one, following the manufacturer’s instructions.
  5. Test the system by turning on the jets, lights, and other features. Check for any issues or irregularities.
  6. Set the desired temperature using the control panel. Allow time for the water to heat up.
  7. Set up and maintain the filtration and sanitization system according to the manufacturer’s instructions.
  8. Learn and follow the recommended maintenance routine, including cleaning, filter replacements, water testing, and chemical balancing.

When To Change the Hot Tub Water

The water in a hot tub should be changed every 3 to 4 months, depending on the frequency of use and the maintenance routine. Regularly testing the water and monitoring its quality is important to ensure it is safe and balanced.

If the water becomes cloudy, has an unpleasant odor, or is difficult to balance despite proper maintenance, it may be necessary to change the water sooner.

Proper filtration, disinfection, maintenance practices, and regular water testing can help prolong the time between water changes.


Should I Leave the Hot Tub Cover Off While Filling?

It is generally recommended to leave the hot tub cover off while filling to avoid trapping moisture and potentially causing mold or mildew.

Can I Use Well Water or Fresh Water To Fill the Hot Tub

Yes, you can fill a hot tub with well water or fresh water. However, it is important to test the water quality before filling the hot tub to ensure it is safe and free from any contaminants.

Suppose the well water has high levels of minerals or other impurities. In that case, you may need to use appropriate treatment methods or consider using a water softener to prevent any issues with the hot tub.

How Often Should I Drain and Refill My Hot Tub?

Spa water should be drained and refilled every 3 to 4 months, depending on usage and maintenance practices.

Can I Use a Chlorine-Free Sanitizer in My Hot Tub?

Yes, there are chlorine-free sanitizers available that can be used in hot tubs and spas. They provide an alternative to traditional chlorine-based sanitizers.

How Often Should I Test the Water Chemistry in My Hot Tub?

It is recommended to test the water chemistry in your hot tub at least once a week or as advised by the manufacturer. This helps ensure proper balance and sanitation.
