What maintenance tasks are due each season?

In spring, start-up (cover, equipment, pH and shock); in summer, weekly chlorine, pH, cleaning and filter visits; in autumn, leaves, less filtration and an equipment check; and in winter, winterising, the cover and periodic checks.

Does a pool need maintenance in winter?

Yes, though less. It needs proper winterising, an eye on the cover and minimal filtration, and protection from frost; that makes the spring opening much simpler and cheaper.

Spring: waking the pool up

Time to move from winter mode to swimming mode without surprises. What happens now decides how the whole summer goes.

Remove and clean the winter cover before the water warms up.
Check the pump, filter and multiport valve, and set filtration to the season pace.
Adjust the pH first, then a shock treatment to start with clean water.
Start the salt chlorinator (if you have one) and check the cell.

Summer: high season

More heat, more swimmers and more chlorine used up. Consistency is what keeps the water clear.

Cleaning the floor, walls, waterline and baskets.
Watching filter pressure and backwashing when it is due.
For residential communities, lifeguard cover during the swimming season.

Autumn: slowing down without neglecting it

The pool gets less use, but leaves and the first rains bring work. The best moment to check the equipment.

Removing leaves often so they do not rot on the floor.
Reducing filtration hours as the temperature drops.
Checking the equipment calmly, now that there is no rush.
Considering a thermal cover to extend the season or protect the water.

Winter: winterising and keeping watch

The pool rests, but it is not abandoned. Good winterising saves a lot of money in spring.

Winterising treatment so the water holds until spring.
Fitting the winter cover and checking it after rain or wind.
Minimal filtration and precautions on frosty nights.
Periodic checks to make sure everything is still in order.
