Did you know that 15% of French households living in individual houses own a swimming pool? Perhaps you are one of them! Today, in France, there are 1.63 million in-ground pools and 1.84 million fixed above-ground pools, over 10 m². Whether your pool is in-ground or above-ground, its winter maintenance is crucial to ensure it remains in perfect condition and ready for use when the warmer weather arrives.
Maintaining your pool in winter is essential to ensure healthy water and protect your equipment. Whether you opt for active or passive winterization, find all our tips to protect your pool and avoid unpleasant surprises in the spring.
Active or passive winterization: an important choice for your pool
Winterization is an essential step to protect your pool during the cold months. But how to choose between active and passive winterization?
Why winterize your pool in winter?
Winterizing your pool is essential to protect your pool and equipment from winter temperatures. This process protects the structure from the effects of frost, reduces the accumulation of dirt, and facilitates restarting in the spring. By adjusting the operation of filtration and treatment systems, you save energy and minimize the use of chemicals while extending the life of your facilities.
Winterizing your pool actively
Active winterization consists of maintaining minimal filtration and equipment during the winter. Filtration is reduced to a few hours per day, which prevents ice formation and protects the hydraulic system. This mode is particularly suitable for regions where temperatures remain mild. All you need to do is use a frost protection box and periodically check the pH, skimmers, and equipment. The advantage is a quicker restart and better water quality in spring.
- Reduce filtration time (1 to 3 hours per day)
- Use winterizing products to limit algae formation
- Regularly monitor water quality

Winterizing your pool passively
Passive winterization, ideal for regions with negative temperatures, involves the complete shutdown of the filtration system and thorough preparation. After a complete cleaning and shock treatment of the water, the level is lowered to protect the nozzles and skimmers. Plugs and floats are installed to prevent frost damage, and a winter cover prevents dirt. This process requires special care, but it guarantees optimal protection of the pool and equipment during the cold season.
- Drain equipment (pump, filter, skimmers)
- Cover the pool with a suitable winter cover
- Install winterization plugs
Good to know: you can start winterizing your pool when the water temperature drops below 12°C.
Maintaining a clean pool, the importance of winter cover and the role of the pump
Maintaining a clean pool in winter ensures a peaceful restart in spring. The winter cover and proper pump operation are essential allies for effective maintenance.
How to keep a pool clean in winter?
Even in winter, it is crucial to keep your pool clean to avoid extensive cleaning work in the spring. Use a winter cover to limit debris and regularly check the water quality. If you have chosen active winterization, ensure that filtration is working effectively and avoid stagnation.
- Regularly remove leaves and debris
- Use specific products to stabilize the water
- Clean the walls and bottom before winterizing
Is it necessary to cover a pool in winter?
If you have chosen passive winterization, it is indeed essential to install a cover on your pool to protect the water from leaves, dust, and bad weather. It also limits the proliferation of algae and maintains healthier water. Investing in a suitable cover greatly simplifies maintenance and also protects the pool structure.
Can I cover my pool and let the pump run?
Covering your pool while letting the pump run is an excellent combination for preserving the water. This method, typical of active winterization, prevents ice formation in the pipes while avoiding the accumulation of dirt. Make sure to use a frost protection box like the DHG-2 to automate the operation if necessary.
Filtration management in winter: optimal shutdown, duration, and speed
In winter, filtration becomes a key element in preserving water quality and your pool. It is essential to ensure that your filtration system is working correctly, even during the coldest periods.
When should pool filtration be stopped?
Filtration can be stopped once the pool is in passive winterization, after purging the system and protecting the equipment. However, if you opt for active winterization, filtration must continue to operate, but at a reduced rate, depending on outdoor temperatures.
Do I need to run a pool pump in winter?
If you choose active winterization, it is necessary to run the pump a few hours a day to prevent freezing in the pipes. This is particularly useful in regions where temperatures are around 0°C.
Good to know: during active winterization, it is recommended to run the filtration pump between 3 AM and 5 AM, during the coldest hours of the night.
At what speed should the pool pump run in winter?
In winter, the filtration speed must be adapted to the temperature. Reduced filtration is generally sufficient to keep the water moving and prevent freezing. For greater peace of mind, you can choose to install a variable speed pump that allows you to adjust the water flow according to your pool's needs.
Preventing frost risks to protect your pool in winter
Good to know: water and equipment in your pool can freeze as soon as the temperature reaches 1 or 2°C.
Is it acceptable for a pool to freeze in winter?
Allowing your pool water to freeze is not recommended, as it can damage the pool structure and equipment. Adopting anti-freeze devices like the DHG-2 frost protection box is essential to avoid damage related to low temperatures.
How to prevent damage caused by frost?
Using a frost protection box is a practical and effective solution to protect your pool in winter. This intelligent device automatically activates the pump when the temperature drops below a certain threshold, usually around 0°C. By maintaining minimal water circulation, the frost protection box prevents ice formation in the pipes and equipment, thus considerably reducing the risk of damage. Easy to install, it offers peace of mind for getting through winter without worry, even during periods of intense cold.
How do I know if my pool water is ready for reuse in spring?
Check the clarity of the water and analyze its parameters (pH, alkalinity, chlorine level). If everything is in order, your pool is ready for a new swimming season.
By applying these tips, you guarantee the longevity of your pool and the quality of its water, winter after winter.
Good to know: proper winterization will allow you to extend the life of your water; you can keep the same water for several years, generally between 3 and 5 years.
Conclusion
Winter maintenance of your pool is a crucial step to preserve water quality, protect your equipment, and ensure a peaceful restart in spring. Whether you opt for active or passive winterization, each method has its advantages depending on your region and needs. By taking appropriate measures, such as using a winter cover, specific products, or a frost protection box, you will avoid unpleasant surprises related to freezing and dirt accumulation.
By following these best practices, you will extend the life of your pool and fully enjoy sunny days as soon as they return.
