‍Hot tubs are a fantastic addition to any home, providing a relaxing retreat for soaking away the troubles of the day. However, like any other investment, they require regular care and maintenance to ensure they continue to deliver a pleasurable experience. One essential aspect of hot tub care is draining the water to clean the tub and replace it with fresh water. This guide will walk you through the process of safely draining your hot tub while keeping your pets, children, and property protected.

1. Understanding the Importance of Draining Your Hot Tub

Draining your hot tub regularly is crucial for maintaining optimal water quality and ensuring the longevity of your investment. Over time, chemical treatments, organic matter from bathers, and other debris can build up in the water, leading to issues such as:

  • Difficulty in balancing pH levels
  • Increased chemical usage
  • Unpleasant odors or tinted water
  • Scale buildup on the hot tub surface

To avoid these problems and keep your hot tub in top condition, it is recommended to drain and refill your hot tub every 3-4 months, depending on usage.

2. Preparing for the Draining Process

Before you begin draining your hot tub, take the following precautions to ensure a smooth and safe process:

  • Ensure the hot tub is not in use: Do not attempt to drain the hot tub while it is still being used by anyone.
  • Protect nearby plants and structures: Make sure any plants, furniture, or other items are far enough away from the hot tub to avoid water damage during the draining process.
  • Choose an appropriate drainage location: Direct the drainage water away from your home’s foundation and avoid draining it into storm drains. Check your local regulations for any specific guidelines on where to dispose of hot tub water.
  • Lay down drop cloths: Protect surrounding areas from water damage by laying down drop cloths or tarps near the hot tub.
  • Turn off the power: Shut off the power to the hot tub at the circuit breaker to prevent damage to the pumps and jets during the draining process.

3. Locating Your Hot Tub’s Drain Valve

Your hot tub should have a drain valve located on its exterior, typically near the base. This valve allows you to easily release the water from the tub. Some hot tub models may have a primary and auxiliary drain valve, with the primary valve being used for the main draining process and the auxiliary valve for removing water from the internal lines. Consult your hot tub’s owner’s manual for specific information on locating and identifying your drain valve.

4. Draining Your Hot Tub Using the Drain Valve

Once you have located your hot tub’s drain valve, follow these steps to drain the water:

  1. Attach a garden hose: Connect a garden hose to the drain valve and direct the other end of the hose to your chosen drainage location.
  2. Open the valve: Turn or pull the valve handle to open it and allow the water to flow out through the hose. This process may take up to 2 hours, depending on the size of your hot tub.
  3. Monitor the draining process: Check the progress periodically to ensure the water is draining correctly and to the desired location.

5. Draining Your Hot Tub with a Submersible Pump

Using a submersible pump is a faster method for draining your hot tub. Follow these steps to drain your hot tub with a pump:

  1. Attach the hose: Connect the pump’s outflow hose and ensure the other end reaches your chosen drainage location. If necessary, attach a garden hose to extend the length.
  2. Place the pump: Position the submersible pump in the deepest part of the hot tub, making sure it sits flat on the floor.
  3. Turn on the pump: Switch on the pump and allow it to remove the water from the hot tub. Monitor the draining process and turn off the pump once the water has been removed. Some pumps have an automatic shut-off feature that will turn off the pump when the water reaches a specific level.

6. Additional Draining Method: Using a Wet/Dry Vacuum

Another method for draining your hot tub is to use a wet/dry vacuum. This method is slower than using a submersible pump but faster than relying on the drain valve alone. Follow these steps to drain your hot tub with a wet/dry vacuum:

  1. Attach the hose: Connect the vacuum’s hose to the machine and place the open end in the water.
  2. Turn on the vacuum: Switch on the vacuum to start the water flow through the hose. Once the water begins flowing, turn off the vacuum and disconnect the hose. The water should continue to flow through the hose.
  3. Direct the water: Position the open end of the hose over your chosen drainage location, allowing the water to flow out.
  4. Remove remaining water: Reattach the hose to the vacuum and use it to suction out any remaining water from the hot tub.

7. Cleaning Your Hot Tub After Draining

With the water drained from your hot tub, it’s time to give it a thorough cleaning. Use a soft cloth and a cleaning product specifically designed for hot tubs to wipe down the tub’s interior surface. Be sure to clean the filter compartment and jets as well.

This is also an excellent opportunity to clean your hot tub filters and ensure they are in good working condition.

8. Refilling Your Hot Tub

After cleaning your hot tub, it’s time to refill it with fresh water. To refill your hot tub:

  1. Place the hose in the filter housing: Position the hose in the filter housing to fill the pipes first, reducing the risk of airlock.
  2. Turn on the water: Begin filling your hot tub with water, ensuring the jets and pumps remain off during this process.
  3. Fill to the appropriate level: Consult your hot tub’s owner’s manual for the correct water level. Typically, you should fill the tub until the water covers the top jet but remains below the headrest.
  4. Turn on the power: Once the hot tub is filled, turn the power back on and add the necessary chemicals to balance and sanitize the water.

9. Frequently Asked Questions

  • Can I drain hot tub water onto my lawn?
    Hot tub water can be harmful to plants and grass due to the chemicals in the water. It’s best to drain the water directly into a drain. If you must drain it onto your lawn, allow the chlorine level to drop below 3 ppm before doing so, and avoid using the hot tub during this time.
  • How do I drain my hot tub completely?
    To remove every last bit of water from your hot tub, use a wet/dry vacuum to suction out water from the jets and any remaining water in the footwell.
  • How often should I drain my hot tub?
    It is recommended to drain and refill your hot tub every 3-4 months, depending on usage.

10. Final Thoughts

Draining and refilling your hot tub is an essential aspect of hot tub maintenance that ensures a safe and enjoyable soaking experience.
