How to Winterise Your Hot Tub: A Step-by-Step Guide

As the days grow shorter and the temperatures plummet, it's time to start thinking about winterising your hot tub. Properly preparing your hot tub for the winter months is essential to protect it from damage and ensure it's ready for use when the warmer weather returns. In this guide, we'll walk you through the steps to winterise your hot tub and keep it in great shape throughout the cold season.

Step 1: Gather Your Supplies

Before you begin the winterisation process, gather all the necessary supplies:

1. Hot tub cover and thermal blanket
2. Spa cover clips or straps
3. Garden hose
4. Submersible pump (optional)
5. Spa filter cleaner and pipe cleaner
6. Spa vacuum (wet and dry vacuum) or net
7. Propylene Glycol antifreeze (Optional).
8. A long funnel if using anti-freeze for pouring the antifreeze into narrow openings.

Step 2: Clean the Hot Tub

Before draining the water, thoroughly clean your hot tub. Remove any debris, leaves, or other foreign objects using a spa vacuum or net. This will prevent clogs when draining.

Step 3: Drain the Water

If using, add the pipe cleaner to the water by following the instructions on the pack. Use a garden hose to drain the hot tub. Ensure that the water is completely drained, including any water in the plumbing lines and jets. If necessary, use a submersible pump to remove any remaining water. Wipe the. surface with a soft cloth to dry the remaining water.

Step 4: Remove and Store the Spa Filter

Take out the spa filter and clean it thoroughly once more. Allow it to dry completely before storing it in a dry, cool place for the winter. A clean filter will extend its lifespan and improve water circulation when you reopen your hot tub.

Step 5: Protect the Plumbing

To prevent freeze damage to the plumbing, you have two options:

- Blow Out the Lines (recommended): Use a wet and dry vacuum to blow out any remaining water from the plumbing lines. Start with the jets and work your way to the pump and heater. Be thorough to ensure no water remains.

- Use Antifreeze (may invalidate some manufacturer warranties): Alternatively, you can use a non-toxic antifreeze designed for hot tubs. Use a funnel to pour a small amount of propylene glycol antifreeze into your jets, your filter standpipes, and any other opening through which water may enter or leave your spa. Please note: never use an antifreeze containing Ethylene Glycol—the kind you use in your car—in your hot tub. It's toxic.

Step 6: Cover and Secure

Place your hot tub cover and if you have one, thermal blanket over the tub and make sure it's secure. Use spa cover clips or straps to hold it in place. This step will help insulate the hot tub and keep debris out during the winter.

Step 7: Regular Maintenance

Throughout the winter, periodically check your hot tub to ensure the cover remains secure and there are no signs of damage or leaks. If you have any concerns, address them promptly to prevent more significant issues.

Word of Caution:

Hot tubs are designed to be used all year long. They are not designed to be left for long periods without water in them. The parts in the hot tub can be damaged if left without water in them and you may find you will need expensive parts replacing when you start it up again.

If you don't feel you will use your hot tub during the cooler months, it is advisable to turn the temperature down to the lowest setting and maintain the water balance for the duration. This will prevent frost damage and the potential for expensive parts to degrade whilst they are not in use.
