How to maintain swimming pools in winter?

When winter coming, and some outdoor swimming pools will be closing soon. If these pools are not properly inspected and maintained after the swimming season, they are prone to malfunctions when they reopen. Therefore, proper maintenance is essential for these pools after the swimming season.

(1) Dry Maintenance:

After the swimming pool is no longer in use, drain the water and clean it thoroughly. Then, when the temperature drops to 0℃, the following methods can be used to prevent freezing and strengthen the maintenance during the winter freezing period: Cover the pool bottom and walls with a pool cover film. Before covering the pool, you need to thoroughly clean the pool body and ensure that the edge of the pool cover is tightly attached to the pool to prevent other substances from falling in and contaminating the pool.

(2) Water Maintenance:

Fill the swimming pool with water for the winter. This method is suitable for areas with no freezing period or a short freezing period in winter. Its advantages are low cost and convenient management. Fish species suitable for the local environment can also be raised in the pool to increase income. The disadvantage is increased algae and rust, which increases the workload of cleaning the pool before its use in the following summer.

Using water maintenance does not mean that the pool can be filled with water and then no management is needed. When the temperature is 0℃, the pool should be maintained more strictly, otherwise the freezing of the pool water will cause damage to the pool. Here are some methods for preventing water-based swimming pools from freezing:

① Keep the area around the pool clean, regularly sweeping and removing debris from the surface to reduce floating and accumulating debris.

② Hang straw mats on the pool walls to prevent the pool from freezing and damaging it.

③ During periods of freezing, use a large wooden mallet to break up floating ice, preventing the ice layers from coalescing.

In addition, in cold climates, it is necessary to completely drain the water from pumps, heating equipment, and sand filters. These devices usually have a drain cover to allow water to drain out, preventing water from freezing and expanding, which could damage the equipment. The above are some maintenance methods for outdoor swimming pools after the swimming season. The appropriate post-season maintenance method can be selected based on the pool's location and specific conditions.
