When the swimming season ends, your pool still needs some care. Even if you no longer use it every day, it is important to keep the water in good condition and prepare the equipment for the colder months. One of the most common questions is what to do with the filtration system: should you keep running it, or is it better to dismantle it?
The answer depends on the climate in your area. In places with mild winters, the filtration system can be run occasionally. In areas where temperatures drop significantly and there is a risk of freezing, it is advisable to dismantle and store the equipment to prevent possible damage.
In areas with a mild climate
In southern regions, where temperatures tend to be milder, the filtration system can be run once or twice a week during winter. How often you need to run it will depend on the condition of the water and the weather.
Before each time you run the system, check that the equipment is in good condition and follow the instructions for your filtration system.
In cold areas with a risk of freezing
In northern regions, where low temperatures and frost can affect the equipment, it is advisable to dismantle and store the filtration system for the winter. Before storing it, drain the water from the pump, filter and pipes to prevent it from freezing inside them. Always follow the manufacturer’s instructions.
Even if you store the equipment, you do not need to empty the pool completely. GRE recommends keeping the water in the pool and winterizing it properly to help maintain it in better condition and make it easier to reopen when warmer weather returns.

Check your pool during winter
Whether you run the filtration system occasionally or store the equipment, check the condition of the water and pool cover from time to time. Remove leaves and other debris, and use pool care products according to the manufacturer’s instructions.
In summary: in areas with a mild climate, the filtration system can be run once or twice a week. In cold areas where there is a risk of freezing, dismantle and store it. In both cases, follow GRE’s recommendations for your pool and equipment.
