Australia’s summer days might have faded, but your pool still needs attention during the colder months. Many pool owners overlook the importance of winterising their pool, leading to unforeseen maintenance costs in the warmer months when you need your pool the most. It also creates unnecessary wear on pool components, and worst of all, damage to that all-important pool liner.
This guide will walk you through everything you need to know about how to properly winterise your pool while protecting your liner from damage. By following these steps, you can help extend your pool liner’s life and ensure your pool stays in top condition, no matter the season.
Why Winterising Your Pool Is Crucial for Pool Liners
Neglecting your pool during winter isn’t just an inconvenience when it heats up in summer, it can also wreak havoc on your pool liner. Cold temperatures, stagnant water, and debris can stain, wrinkle, or even damage the liner. Left unchecked, your pool liner may require premature replacement, which could cost thousands of dollars.
Fortunately, with some seasonal maintenance and the right approach, winterising your pool can help you avoid costly repairs. One essential step? Using a pool winteriser to protect both your water and your liner during the colder months.
Here’s why winter upkeep matters:
- Prevents Damage From Debris: Leaves, dirt, and other debris can settle on your liner, leading to staining and weakening of the material over time.
- Avoids Algae Growth: With stagnant water, algae thrive and often stick to liners, leaving discolouration or stains.
Reduces Maintenance Costs: Regular winter care avoids serious problems, saving you from labour-intensive clean-ups or paying for a liner replacement down the track.
Step-by-Step Guide to Winterising Your Pool
1. Clean Your Pool Thoroughly
Start with a fresh slate by removing all dirt and debris from your pool. Follow these steps:
- Use a skimmer to remove leaves and debris from the water surface.
- Vacuum the pool floor to remove dirt and small particles.
- Brush the walls and floor to eliminate residue that could stain the liner.
Pro Tip: Organic materials like leaves can lead to staining if left sitting on the liner for too long.
2. Test and Balance Your Water Chemistry
Balanced water chemistry is essential to protect your liner and equipment. Test your water and ensure the following levels are within the recommended ranges:
- pH: 7.2–7.6
- Alkalinity: 80–120 ppm
- Calcium Hardness: 200–400 ppm
Imbalanced water can lead to liner wrinkling, fading, and deterioration, so it’s worth spending the extra time to get these levels right.
3. Add a Pool Winteriser
A good winteriser is key to maintaining water quality and protecting your liner during winter. These specialised chemicals:
- Prevent algae growth.
- Reduce bacteria levels.
- Protect the liner by maintaining water condition.
For Saltwater Pools: Use a winteriser designed specifically for salt systems to avoid equipment corrosion.
4. Set Pool Equipment for Winter
How Long Should You Run Your Salt Chlorinator?
During colder months, you can typically reduce the runtime of your salt chlorinator to 4–6 hours a day. However, this may vary depending on your pool’s size, region, and winter temperatures.
How Long Should the Pump Run?
For most pools, running the pump for 1–4 hours a day in winter is enough to circulate the water and distribute chemicals. Be sure to check your system’s manual for recommendations on winter settings.
What Is the Winter Setting on Your Pool Pump?
If your system includes a “winter” or “recirculate” mode, use it to bypass the filter and keep water moving during reduced operation. This prevents dirt build-up in your filtration system during the off-season.
5. Clean and Backwash Your Filter
Before shutting down for winter, give your pool filter a thorough cleaning:
- Sand Filters: Perform a backwash to remove sand and debris.
- Cartridge Filters: Rinse the cartridge with clean water.
- DE Filters: Clean the grids and add fresh DE powder if required.
Taking these steps ensures optimal water flow, even during reduced winter use.
6. Salt Maintenance During Winter
Wondering how often to add salt to your pool in winter? Rain and evaporation can reduce salt levels, so it’s a good idea to test and top up salt monthly, even during colder months. Proper salt levels help keep your pool liner and equipment corrosion-free.
7. Cover Your Pool
A fitted pool cover is one of the easiest ways to protect your pool and liner during winter. Here’s how a cover can help:
- UV Protection: Prevents the liner from fading under winter sunlight.
- Debris Reduction: Keeps leaves and dirt from settling on the water’s surface.
- Temperature Conservation: Insulates your pool water, maintaining stable temperatures.
Choose the best type for your needs:
- Solar Cover: Provides light insulation while promoting heat retention.
- Thermal Blanket: Offers the highest insulation against cold weather.
Mesh Cover: Blocks debris while allowing rain and snowmelt to pass through.
Pro Tips to Extend the Life of Your Pool Liner
- Avoid Draining the Pool Fully: A drained pool risks causing the liner to shrink or crack. Always maintain water at the recommended level.
- Use Liner-Friendly Chemicals: Only use chemicals designed for vinyl liners to prevent damage.
- Inspect Your Liner Regularly: Look for tears, wrinkles, or stained areas and address them promptly.
Common Mistakes to Avoid When Winterising a Pool
- Draining below the skimmer line improperly.
- Forgetting to clean the pump baskets or filters.
- Running the chlorinator excessively in low temperatures.
