How to Winterize Hot Tub in 6 Easy Steps

If you’re not going to use your hot tub this winter, you should close it entirely to avoid freezing. It is advised that you winterize your hot tub before the temperature drops below five degrees. Winterizing a hot tub is important for both safety and saving money on utilities.

Step 1: Flush the Lines

Before you drain your hot tub, you should flush the lines to remove any dirt, bacteria, or biofilm that may have accumulated in the pipes. You can use a commercial line flush product or a homemade solution of vinegar and water. Follow the instructions on the product label or add about a cup of vinegar per 100 gallons of water. Run the jets for 15 to 20 minutes, then turn off the power and proceed to the next step.

Step 2: Drain the Hot Tub

The next step is to drain your hot tub using a submersible pump, a siphon hose, or the built-in drain valve. Make sure to empty all the water and follow the proper disposal guidelines. You might have to lean the hot tub a bit to remove any leftover water. After that, you need to clean the plumbing pipes of any remaining water.

To do this, you need to access the pumps and other parts by removing the panels on the hot tub. Locate the pumps and disconnect the pipe from each one. Use plumbing pliers to loosen the couplers that attach the pipes to the pumps. Don’t forget to get the O-ring from the pipe after disconnecting it. Then, use a wet/dry vacuum to blow and suck out the water from the pipe.

Step 3: Dry the Hot Tub

After draining the hot tub, you should dry it thoroughly to prevent any moisture from freezing and cracking the shell or the components. You can use a sponge, a towel, or a wet/dry vacuum to soak up any water from the surface, the jets, the filter housing, and the skimmer. Pay special attention to the corners and crevices where water may hide.

Tips

Lubricate the O ring and seals, This will help protect the seals from drying out during the winter months.

 

Step 4: Clean the Filter and the Shell

Once the hot tub is dry, you should remove the filter and clean it with a filter cleaner or a mild detergent. Rinse it well and let it air dry. You should also clean the shell of the hot tub with a non-abrasive cleaner or a mild bleach solution. Wipe it down with a soft cloth and rinse it with clean water.

Step 5: Add Antifreeze

To prevent the pipes from freezing and bursting, you should add antifreeze to the plumbing system. You can use a non-toxic propylene glycol antifreeze that is safe for hot tubs and the environment. Do not use automotive antifreeze, as it can damage the hot tub and harm your health. To add antifreeze, you can either pour it directly into the jets and the drain valve, or use a funnel and a hose to inject it into the pipes. You should use about a gallon of antifreeze per jet. Make sure to cover all the openings with duct tape or plastic wrap to seal the antifreeze inside.

Step 6: Secure the Cover

The final step is to secure the cover of the hot tub to protect it from snow, ice, and debris. You should use a high-quality cover that is insulated and waterproof. You should also use a cover lifter or a strap to keep the cover in place and prevent it from blowing off. You may also want to add a layer of plastic or tarp over the cover for extra protection.
