The wintering of a swimming pool is essential to keep it safe from frost. It not only conserves the quality of the water in the basin but also protects the equipment. However, if the wintering of the swimming pool is badly carried out, there is a strong risk of endangering the pump, the piping, the skimmers, the walls of the swimming pool or the liner for example. Here are five mistakes to avoid if you want to benefit from the benefits of a clean water bath in the spring.
Error # 1: keep a pool full of water during passive wintering
Passive wintering for a swimming pool equipped with a pump and a filter located in a technical room involves eliminating all the water contained in the filtration circuit. To do this, only one solution is necessary: very partially drain the water from the pool so that its level arrives just below the skimmers or discharge nozzles. Drains that no longer contain water will not risk freezing. It is advisable to supplement this precaution by insulating the pipes. Attention: in case of active wintering, it is advisable to keep a sufficient level of water for the filtration systems to function.
Error # 2: completely empty the pool
To put a swimming pool in winter, you must not empty it entirely. Completely draining the pool will have irreversible repercussions on its structure. The weight of the water, which is several tonnes, is the only one that can resist resistance to the pressure of the soil on the walls of the pool. Without this opposition, the pool is seriously exposed to the risk of cracks. It is also the water that keeps the liner perfectly in place. Finally, the ten-year guarantee lapses in the event of total draining of the pool.
Error N ° 3: put your swimming pool in winter when the water displays more than 12 ° C
This is a serious error. The wintering of a swimming pool must be carried out when the swimming pool water reaches a constant temperature of 12 ° C. At a higher temperature, bacteria and algae proliferate. It will then be compulsory to treat the water in the spring, when the pool is put back into service, which implies a non-negligible expense.
Mistake 4: Waiting too long for the pool to be put back into service
If the ideal swimming pool water temperature is 12 ° C at the time of wintering, it is also 12 ° C to decide to return the swimming pool to service in the spring. If we wait until the sun warms the water, there again risks a proliferation of microorganisms which will only make the water unsuitable for swimming. It is also important to remove the cover a few days before returning to service.
Error N ° 5: restart the filtration system without prior cleaning
After winterizing the pool, it is essential to first clean the sand filter, the skimmers and the baskets before restarting the filtration system. A cartridge filter requires the replacement of the old cartridge while the diatomite filter requires a refill. After a few days, and before the first swim of the year, a water analysis and treatment is required.
