Proper pool care is essential to keeping it in optimal condition throughout the year. When the swimming season comes to an end and winter approaches, it is crucial to understand the pool winterization process.
As we have already mentioned, this is a process carried out at the end of the pool season, generally before winter arrives or before cold temperatures make it impossible to use the pool. The main objective is to protect it from damage caused by low temperatures and frost, as well as to reduce the maintenance required during the period of inactivity.
In addition, you will also ensure that it is ready for the next swimming season. For this reason, in this article we tell you everything you need to know to winterize your pool effectively, thereby ensuring its durability and water quality.
Benefits of winterizing the pool
Winterizing the pool, or carrying out the winterization process, offers a number of important benefits. Below, we explain some of the most notable ones:
- Pool winterization protects its structure and systems from the harmful effects of low temperatures and frost. It prevents the water from freezing and expanding and therefore extends the pool’s service life.
- Pool winterization can save money in the long term by reducing the risk of algae growth in the water and the need for costly maintenance and repairs in winter. Preventing damage is always better than having to pay for expensive repairs.
- Using the right products and maintaining the water balance during winterization will help preserve the water quality. This way, when you use your pool again, it will be easier and quicker to get it up and running.
- Finally, by carrying out this process, you will not need to empty the pool, which means you will also be saving water and money, as well as avoiding the emptying process and all the cleaning it entails. You will also avoid the risk of cracks forming in the walls, which will be less exposed to harsh weather conditions.
For all these reasons, winterizing the pool is a recommended practice: it protects your investment, simplifies maintenance, saves water and time, and ensures a quick start-up next season.
When should you winterize the pool?
The right time to winterize the pool generally depends on the region where you live and local weather conditions. This means you may need to do it earlier or later in the year. However, regardless of this, you should wait until the water temperature is below 15 ºC; otherwise, the water could deteriorate and this process would not help us at all.
How should you winterize the pool?
As you may have noticed, effectively winterizing the pool is an essential process for protecting it during the winter season and ensuring that it remains in good condition for the next swimming season. Here are the key steps for winterizing your pool:
- Start by cleaning the pool thoroughly. Use a brush and, if necessary, apply a descaler or a pool algaecide. Also, make sure to use the pool vacuum to remove any suspended particles.
- Keep the water’s pH values within the range of 7.2–7.6. Use specific products to test and adjust the pH as necessary.
- Carry out a shock chlorination treatment to help keep the water free of contaminants during the period of inactivity.
- Keep the pool’s filtration system running to keep the water circulating. This helps distribute the products properly and prevents stagnation problems.
- The day after completing the previous steps, add a pool winterizer and make sure the filtration system is running for at least 8 hours to ensure uniform distribution of the winterizer throughout the water.
- The day after adding the winterizer, carry out a complete filter wash to maintain its efficiency and performance during the period of inactivity.
- If you live in an area with very cold winters, it is advisable to lower the water level below the skimmers, drain the pipes and filter, and place floating objects, such as a winter float, in the pool to relieve the pressure of ice on its surface.
- In contrast, in milder climates, it is advisable to run the filter periodically, whenever possible, to keep the water moving and prevent stagnation problems.
- Do not forget to cover the pool with a good winter cover to protect it. If you do not have one, it is advisable to periodically remove any dirt and leaves that may have accumulated using a leaf net.
It is important to repeat the addition of the winterizer every 3 months to maintain adequate protection throughout the winter. In addition, you should monitor whether the filter pressure gauge shows that it is in the red zone, as it will then be necessary to perform a backwash to clean the filters.
In the event of torrential rain, carry out a shock treatment and then check the chlorine and pH levels.
By following these steps, you will be able to winterize your pool efficiently and keep it protected throughout the winter, making start-up easier next season!
Passive winterization VS active winterization
Pool winterization can be carried out in two ways: passive winterization and active winterization. Each approach has its own advantages and considerations, and the choice between one or the other depends on your preferences and budget. And at piscinas y productos, we want you to have all the information you need to make the best decision!
You can choose active winterization if your pool does not have a winter cover, if you want to enjoy views of your pool during the winter, and if you want a quick start-up in spring. It is ideal for locations where winters are mild.
On the other hand, choose passive winterization if you do not want to monitor the filtration system, if you have a winter cover, and if your pool is located in an area with a high risk of freezing. In this case, you must switch off the filtration system completely. It is commonly used in second homes.
