Quick answer: After the season, take care of cleaning, balancing the water, lowering the level according to the technology, protecting the pipework, the filtration, the pump, the cover, and checking for damage.
Winterizing is cheaper than spring repairs. Most damage occurs where water is left in pipework, the pump, or technology not designed for frost.
What to Check Before Ordering
- Cleaning the bottom, walls, skimmer, and baskets.
- Checking pH and disinfection before shutdown.
- Lowering the water level according to the pool type and technology.

- Protecting the pump, filter, and heating.
- Checking the cover, enclosure, and safety.
Most Common Mistakes
- Winterizing dirty water.
- Leaving water in the pump or heat pump.

How to Decide
If you are not sure about the technology, have the first winterization done by a professional and document the procedure. In following years you will already know what your pool needs.
FAQ
Does the pool have to be fully drained for winter?
Usually not. It depends on the construction, the technology, and the manufacturer’s recommendation.
When should you winterize?
Usually once the water temperature drops and biological activity is lower, but still before the frosts arrive.
Next Step
Book the service well in advance and ask for a handover checklist, so that in spring you know what was disconnected and protected.
