Winter pool care tips

Winter often means your pool gets less attention—but that's exactly when many problems begin. A little maintenance during the cooler months can save you time, money and frustration when swimming season returns. Good winter pool maintenance doesn't take much time, but it can save you hundreds of dollars in repairs and chemicals when warmer weather returns.

Here are five of the most common mistakes pool owners make during winter, and how to avoid them.

1. Turning Your Pool Off Completely

It can be tempting to switch everything off to save on electricity, but this is one of the biggest mistakes pool owners make.

Without circulation and sanitisation, algae, bacteria and debris can quickly build up. What looks like a money-saving decision in winter can become an expensive clean-up in spring.

Instead:

Run your filtration system for around 4–6 hours per day (depending on your pool and local conditions).
Check your pool every week or two.
Remove leaves and debris before they sink and stain the pool.

2. Not Testing Your Water

Just because you're not swimming doesn't mean your water chemistry stays balanced.

Rain, wind, falling leaves and cooler temperatures can all affect your pool water.

Even during winter, regularly check:

pH
Free Chlorine
Total Alkalinity
Salt Level (for salt pools)
Stabiliser (Cyanuric Acid)

Maintaining balanced water helps protect your pool surface and equipment while preventing algae from taking hold.

3. Ignoring Your Chlorinator Cell

Your chlorinator continues to play an important role during winter.

Over time, calcium deposits can build up on the cell plates, reducing chlorine production and placing extra strain on the system.

During winter:

Inspect the cell every few weeks.
Clean it only if calcium build-up is visible.
Replace worn cells before summer arrives.

Winter is an ideal time to replace ageing equipment so you're ready for the busy swimming season.

4. Forgetting to Clean the Filter

Your filter works hard all year round. A dirty filter reduces water flow, makes your pump work harder and can affect water clarity.

Whether you have a cartridge, sand or media filter, regular cleaning or maintenance throughout winter helps keep everything operating efficiently.

If your filter cartridge is looking worn or damaged, replace it before spring arrives to keep your filtration system operating efficiently

5. Waiting Until Spring to Fix Equipment

Small problems rarely fix themselves. A noisy pump, leaking O-ring or ageing chlorinator might still be working—but waiting until spring often means:

Higher repair costs
Equipment failure during peak swimming season
Unnecessary downtime

Winter is the perfect opportunity to inspect your equipment and replace worn parts before demand increases.

Winter Pool Maintenance Tips to Keep Your Pool Ready for Summer
