Hot Tub Winterization Guide

Getting your hot tub ready for the colder months is crucial if you want to keep it in great shape. Whether you plan to use your hot tub during winter or shut it down until spring, proper hot tub winterization can help prevent costly damage and extend its lifespan. This guide will walk you through everything you need to know to winterize your hot tub like a pro.

Why Winterizing Your Hot Tub Matters

Freezing temperatures can wreak havoc on your hot tub's plumbing, pumps, and equipment if water is left inside. When water freezes, it expands, potentially cracking pipes and damaging essential components. Proper winterization helps protect your investment, whether you’re shutting it down for the season or keeping it running during the winter.

1. Decide: Winterize or Keep It Running?

First things first, decide whether you want to keep your hot tub running during winter or shut it down. Both options have their pros and cons:

• Keep It Running: Enjoy a warm soak in the cold months! However, this means you’ll need to keep up with regular maintenance, including water chemistry and cleaning.
• Winterize: If you’re not planning to use your hot tub, fully winterizing it can prevent damage and save on energy costs.

2. Clean and Drain the Hot Tub

Before shutting down your hot tub for winter, it's essential to clean and drain it thoroughly. Follow these steps:

• Step 1: Add a hot tub cleaner to the water and run the jets for about 20 minutes to clean out the pipes.
• Step 2: Turn off the power at the breaker to avoid any electrical hazards while draining and cleaning.
• Step 3: Connect a garden hose to the drain valve and let the water completely drain out of the tub. You can also use a submersible pump to speed up the process.
• Step 4: Remove and clean the filters with a filter cleaner. Allow them to dry completely before storing them away for winter.

3. Remove Water from the Pipes

One of the most critical parts of hot tub winterization is removing water from the plumbing lines. Water left in the pipes can freeze and expand, causing cracks and leaks. Here’s how to do it:

• Step 1: Use a wet/dry vacuum to blow air through the jets, drains, and other openings. This will force any remaining water out of the pipes.
• Step 2: Set the vacuum to blow mode and attach it to the jets and air controls to ensure all water is removed from the system.

Double-check that no water is left inside the plumbing or equipment. Taking the time to remove all water now can save you from costly repairs later.

4. Clean the Hot Tub Shell

Now that your hot tub is empty, give it a good cleaning to remove any dirt, oils, or residues. Use a non-abrasive cleaner designed for hot tubs to avoid damaging the shell.

• Gently scrub the surface with a soft cloth or sponge.
• Rinse thoroughly to remove any cleaning residue.

Dry the interior of the hot tub with a towel to ensure no moisture is left behind.

5. Remove and Store Filters

Cleaning your filters is a must before storing them for the winter. Use a filter cleaner to remove any debris and contaminants.

• Soak the filters in a filter cleaner solution for a few hours, then rinse thoroughly.
• Allow them to dry completely before storing them in a dry, cool place.

Storing the filters dry helps prevent mold and mildew growth, ensuring they’re ready for use when you open the hot tub back up in the spring.

6. Secure the Hot Tub Cover

Your hot tub cover plays a vital role in protecting the interior from snow, ice, and debris. Make sure it’s in good condition before winter hits:

• Clean the cover with a mild cleaner and let it dry completely.
• Apply a vinyl protector to keep the cover’s material supple and water-resistant.
• Ensure the cover fits securely over the hot tub. Consider using cover straps or clips to hold it in place during high winds or heavy snowfall.

7. Add an Air Pillow (For Above-Ground Hot Tubs)

If you have an above-ground hot tub, consider placing an air pillow under the cover. The pillow helps distribute the weight of snow and ice, reducing pressure on the cover and preventing damage.

• Place the inflated air pillow in the center of the hot tub before securing the cover.
• This also helps prevent water from pooling on the cover, making snow removal easier.

8. Check on Your Hot Tub Periodically

Even when winterized, it’s a good idea to check on your hot tub periodically throughout the winter months. Look for signs of water or moisture inside, check the cover for damage, and clear off any heavy snow buildup.

• If you notice any water inside, remove it immediately to prevent freezing and damage.

9. Winterize the Hot Tub Pump and Heater

If you’re winterizing your hot tub entirely, don’t forget to winterize the pump and heater. Here’s how:

• Remove the pump and store it in a warm, dry place if possible.
• If the heater has a drain plug, remove it to let any residual water drain out.

Storing the pump and draining the heater helps prevent freezing and potential damage to these vital components.

Conclusion

Winterizing your hot tub might seem like a chore, but it's well worth the effort to protect your investment. By following these hot tub winterization tips, you can prevent freezing damage, avoid costly repairs, and ensure your hot tub is ready to go when spring rolls around. Whether you choose to keep your hot tub running or shut it down for the season, taking the time to winterize properly will save you headaches and money in the long run.
