Swimming pool winterization: essential maintenance steps

Proper maintenance of swimming pools during the autumn transition is essential to prevent equipment damage caused by frost and biological growth. For tubular pools with a volume of less than ten cubic meters, experts recommend draining, dismantling, and storing the unit dry to avoid fatal pressure on the walls and cracking of the PVC liner.

For larger structures, passive winterization is advised, utilizing appropriate products, floats, and opaque covers. A critical thermal threshold for covering a pool is 12°C; covering water while it is warmer can create an incubator effect, encouraging the multiplication of algae and microorganisms.

Depending on the climate, owners can choose between active winterization, which maintains slow filtration for mild winters, or passive winterization, which involves lowering water levels and draining pipes for more rigorous climates.
