As the chilly winter months approach, you may find yourself wondering how to protect your hot tub from the freezing temperatures. If you’re not planning on using it this season, learning how to winterize a hot tub is a crucial step in ensuring it remains in top condition. And fortunately, it’s not as complicated as you might think. 

In this step-by-step guide, we’ll walk you through the process of how to winterize a hot tub to keep it safe and sound until the warmer days return.

How to Winterize a Hot Tub

Step 1: Gather Your Supplies

Before you begin, make sure you have all the necessary supplies on hand. You’ll need:

  • Submersible pump
  • Hose
  • Wet/dry vacuum
  • Spa cover
  • Hot tub cleaner
  • Non-abrasive sponges
  • Filter cleaner

Step 2: Allow the Chemical Levels to Drop

Before draining your hot tub, you’ll need to let the chemicals dissipate to prevent them from harming any plants or wildlife. It may take a few days, but once you can see that the chlorine or other sanitizer levels are at 0, then you can officially start winterizing.

Step 3: Turn Off the Breaker and Drain the Water

Safety first: make sure there is no power going to your hot tub. Depending on your setup, this means you’ll either need to turn it off at the breaker or just unplug it.

Then, using a garden hose (and/or submersible pump to save time), drain the water from your hot tub. Since every hot tub is different, be sure to break out your owner’s manual and follow the manufacturer’s guidelines for your specific model. For example, if your hot tub has an air blower, you will need to follow additional steps to drain it properly before moving onto the next step.

Step 5: Loosen the Unions to Drain Water from the Plumbing Lines

In the cabinet, open the access panel to find the heat and pumps. Then, loosen the unions to get the water out of the plumbing lines. You can also remove the drain plug on the pump(s) to allow the water to drain out, if applicable.

Step 6: Remove and Clean the Filters

Since you’re not going to be using them anyway, this is a great chance to remove and clean your filters with a filter cleaner. Or, if they’re beyond cleaning, dispose of them entirely and start fresh next season. Either way, once the filters are out of there, be sure to soak up any water left in the well.

Step 7: Blow Out the Lines

To ensure all water is removed from the plumbing, use a wet/dry vacuum to blow out the lines. Start with the skimmer and main drain, and work your way through all the jet lines. This step is crucial, as any remaining water can freeze and lead to costly repairs. In fact, you may even want to go over them again for good measure.

Step 8: Clean and Cover the Hot Tub

Now that all of the water is gone, it’s time to give your hot tub a good cleaning inside and out. For best results, use non-abrasive sponges and hot tub cleaner for a thorough clean. Don’t forget under the headrests!

Finally, clean your cover and secure it over the hot tub. If it locks, then make sure to lock it to help keep out any critters looking for a safe, cozy place to call home for the winter.

The Bottom Line

By following this step-by-step guide on how to winterize a hot tub, you’ll keep your investment safe and sound during the colder months. Proper winterization ensures your hot tub will be ready for you to enjoy once the snow melts and the temperatures rise, so be sure to do a thorough job.

Now, go ahead, cozy up by the fire, and dream of the relaxing soaks you’ll have in your well-maintained hot tub when spring arrives!
