How Do I Winterize My Hot Tub If I Won’t Be Using It?

Drain the hot tub completely, remove all water from the plumbing using a blower, and add antifreeze to the pipes. Cover the tub securely to protect it from snow and debris.

Why Winterizing Your Hot Tub Is Essential

Winterizing your hot tub is a must to protect its components from freezing. If water is left in the pipes and equipment, freezing can cause cracks in the plumbing, pump, or heater, leading to costly repairs. Freezing water can block water flow and cause significant damage to the system. Winterizing reduces these risks, ensuring that your hot tub remains in excellent shape for when you want to use it again.

What Happens If You Don’t Winterize Your Hot Tub

Failing to properly winterize your hot tub can lead to serious issues like broken plumbing or damage to the hot tub’s heating system. The freezing water can expand and crack pipes, pumps, and equipment, leading to expensive repairs. This is especially crucial for those living in areas where the winter temperatures are consistently below freezing.

What You Need to Winterize Your Hot Tub

Before you get started with the winterization process, make sure you have the following tools and materials on hand:

• Wet/dry vacuum

• Spa cleaner

• Antifreeze (optional)

• Thermal blankets or foam insulation

• Durable, weather-resistant cover

• Bucket for draining water

By gathering these items in advance, you’ll save time and ensure you don’t miss any critical steps during the process. Winterizing your hot tub is a must to protect its components from freezing.

Winterizing reduces these risks, ensuring that your hot tub remains in excellent shape for when you want to use it again.

1. Clean Your Hot Tub Thoroughly

The first step in winterizing your hot tub is to clean it properly. This ensures that no debris or dirt is left behind to cause issues later.

• Drain All Water: Start by draining all the water from the hot tub. Make sure to remove any water from the cover as well.

• Scrub the Shell: Use a spa cleaner to scrub the interior surfaces. This will prevent buildup that could affect the tub’s performance when you reopen it.

• Clean the Filter: Remove the filter and clean it thoroughly. A dirty filter can reduce efficiency, making it harder to get your hot tub back to top shape later on.

2. Drain the Hot Tub Completely

After cleaning, it's important to drain the hot tub completely. Any leftover water can freeze in the pipes, leading to cracks and damage. Here's how to do it effectively:

• Use the Drain Valve: Open the drain valve to let the water flow out. You may need to tilt the hot tub slightly to ensure all water drains from the lowest parts.

• Empty Water from the Cover: Don’t forget to drain the water from the hot tub cover, as it can freeze and cause strain on the cover material.

• Check for Remaining Water: Double-check the pump and pipes for any remaining water. You want the tub completely dry before moving on to the next step.

3. Blow Out the Plumbing Lines

Once you have drained the water, use a wet/dry vacuum or a blower to get rid of any water left in the plumbing lines. This is a critical step to ensure that no water remains in the system. If any water is left in the pipes, it could freeze and expand, leading to serious damage.

• Use a Wet/Dry Vacuum: Attach the hose to the vacuum’s exhaust port, and blow air through the system.

• Clear the Jets: Don’t forget to clear any jets that may have water trapped inside them.

• Blow Out the Equipment: Be sure to also clear any remaining water from the pump, heater, and filter system.

4. Add Antifreeze to Protect the Plumbing (Optional)

Some people opt to add non-toxic antifreeze to their hot tub’s plumbing system for extra protection during the winter months. While this step is optional, it can help prevent freezing in the pipes and safeguard the equipment.

• Choose the Right Antifreeze: Make sure you’re using an RV-approved, non-toxic antifreeze that is safe for your hot tub’s system.

• Follow Manufacturer Instructions: Pour the antifreeze into the plumbing system according to the manufacturer's guidelines. This ensures the antifreeze is added in the correct amount and distributed properly.

5. Insulate and Cover Your Hot Tub

Once the plumbing lines are clear, it’s time to insulate the hot tub and cover it to protect it from the cold weather.

• Use a High-Quality Cover: Invest in a durable, weather-resistant cover that fits snugly over your hot tub. This will prevent debris, snow, and ice from getting inside.

• Add Extra Insulation: Some homeowners use foam insulation or thermal blankets around the outside of the tub to provide additional protection against extreme cold.

• Secure the Cover: Ensure the cover is tightly secured. A loose cover can let in moisture, debris, or animals, which can cause problems.

6. Check the Hot Tub Periodically

Even after you’ve winterized your hot tub, it’s still important to check on it periodically during the winter.

• Inspect the Cover: Make sure the cover remains in good condition and is securely fastened.

• Clear Snow and Ice: Remove any snow or ice buildup from the cover to prevent it from freezing to the tub or adding excess weight.

• Look for Damage: Check for any signs of damage or wear and tear. Fix any issues before they become bigger problems.

Winterizing your hot tub may seem like a hassle, but it’s a crucial step to ensure it stays in great shape during the colder months. By following these simple steps, you’ll protect your hot tub from freezing temperatures and avoid costly repairs. When you’re ready to enjoy it again, your hot tub will be ready for a smooth restart.

Maintaining your hot tub during the winter is key to extending its lifespan. By cleaning, draining, blowing out the lines, and covering it properly, you’ll avoid potential issues and have a hot tub ready for use once the temperatures rise again.
