Winter maintenance is mainly focus on the pool water due to the temperature drop. There is no ice and snow in some areas, but attention should also be paid to preventing mosquito and flies in the pool water.

      If the pool is located in a cold area, maintain the pool for the winter before the temperature drops to 0 degrees Celsius, and try to close the pool before December to prevent freezing. Due to the volume expansion of water in the pool equipment during the icing process, it is going to result in a large number of economic losses when pipes and equipment are cracked.

      1.Clean the pool
      Water won't be filtered or chemically treated in the winter, so it's very important to make sure the water isn't dirty when you open the pool in the spring.
      2.Clean the filtering system
      Set the filter to "Backwash" mode until the water becomes clear again. Then switch the filter to "Rinse" for about four minutes.
      3.Add anti-freezing solution
      4.Using pool cover
      To prevent winter rain and snow, at the same time to avoid skimmer or pipe damage from freezing.
      5.Cut off the power supply system
      Put the pump and some small accessories (unscrew the pressure gauge, small glass observation bottle) in the storage room to prevent freezing in winter.

      Do not reopen until the hot summer. It is better to open the cover before 21 degrees Celsius to make it easier to clean up the pool since the algae likes to grow at around 21 degrees Celsius.
