Protect your investment, minimise maintenance, and make spring a breeze.
As temperatures drop across Australia, your backyard oasis might not be getting as much attention but that doesn’t mean it should be neglected. Whether you plan to continue using your pool or spa throughout winter or shut it down until spring, proper winterisation is essential to keep your equipment running smoothly and extend its lifespan.
Here’s your complete, Aussie-friendly guide to winterising your pool or spa the right way.
Why Winterise at All?
Even though many parts of Australia don’t experience harsh winters, cold temperatures, rain, and lack of use can still lead to:
Buildup of algae and bacteria
Damaged equipment or plumbing
Higher spring cleaning and repair costs
Cloudy or unbalanced water
A little prep now will save you time, money, and frustration later — and ensure a smoother transition when you’re ready to dive back in.
How to Winterise Your Pool
1. Give it a deep clean
Start by removing all debris, brushing down the pool walls and floor, vacuuming thoroughly, and emptying the skimmer and pump baskets. A clean pool is much easier to maintain over winter.
2. Balance your water chemistry
Check your pH, alkalinity, and calcium hardness. Then, shock the water with chlorine to eliminate bacteria and organic matter. Consider using a long-lasting algaecide to prevent green surprises in spring.
3. Clean your filter
Whether you use a sand, cartridge, or media filter, give it a proper clean so it’s not holding contaminants over winter. This step is crucial if you’re keeping the pool running.
4. Decide to run or rest
If you’re keeping the pool running:
Reduce the filtration hours (3–4 hours/day is usually enough)
Check regularly and adjust chemicals as needed
If you’re switching it off:
Lower the water level if needed Add a pool cover Isolate power to the equipment
5. Cover it up
Invest in a strong, properly fitted pool cover. It will reduce evaporation, keep out leaves and debris, and maintain stable water chemistry.
💦 How to Winterise Your Spa
1. Drain or keep running?
If you plan to enjoy a warm soak on chilly nights (and why not?), simply:
Maintain water levels
Keep the temperature at a moderate setting
Test and adjust chemicals regularly
Use a tight-fitting spa cover when not in use
If you’re shutting it down completely:
Turn off the power and drain all water
Use a wet/dry vacuum to remove water from jets and pipes
Clean and dry the shell, jets, and filters
Leave air and drain valves open to prevent pressure build-up
Cover the spa with a high-quality insulated cover
