🧰 What You’ll Need:

• A submersible pump or garden hose
• Wet/dry vacuum (like a Shop-Vac)
• Hot tub cleaner
• Soft cloth or sponge
• Spa cover
• Non-toxic pool antifreeze (optional)

🪜 Step-by-Step Winterizing Instructions

1. Turn Off the Power

Before you do anything, turn off the hot tub at the breaker. This keeps you safe and protects the equipment.

2. Drain the Water

Use a submersible pump or the drain plug to empty the tub. Make sure all the water is out of the shell and pipes.

3. Clean the Tub

Wipe down the inside of the tub with a spa-safe cleaner. This helps prevent mold and mildew while it’s not in use.

4. Remove and Clean the Filters

Take out the filters and clean them with a hose. Let them dry completely before storing them indoors.

5. Blow Out the Pipes

Use a wet/dry vacuum to blow air through all the jets and plumbing lines. This step is super important—any leftover water can freeze and crack the pipes.

6. Add Pool Antifreeze (Optional)

Some people add non-toxic pool antifreeze to the pipes for extra protection. If you do this, make sure to flush it out in the spring before using the tub again.

7. Cover It Up

Put on a strong, insulated spa cover. This keeps out snow, ice, and animals. If you have a cover cap or tarp, use that too for extra protection.

🧊 Why Winterizing Matters in Ontario

Ontario winters can drop below -20°C. If water freezes inside your hot tub’s pipes or pump, it can cause serious damage. Fixing that can cost hundreds—or even thousands—of dollars. Winterizing is a smart way to protect your investment and make sure your hot tub is ready to go when spring returns.

✅ Final Tips

• Start winterizing before the first big freeze.
• Check your owner’s manual for any special instructions.
• If you’re unsure, consider hiring a professional to do it for you.
