We advise you to restart your pool as soon as the water temperature is around 10-12 °C. Be careful, however, if you use salt treatment by electrolysis you must wait for 15 °. If you have correctly carried out your wintering, restarting will be a simple formality. As a general rule, this is done in March/April (depending on your region) because the water is still at a low temperature and algae have not proliferated.

Recommissioning the swimming pool after active wintering

If you performed an active winterization (i.e., you kept the filtration running all winter), it means you were able to maintain water quality. The recommissioning will therefore be a straightforward step.

  1. Adjust the daily filtration time based on the temperature. (Filtration time = water temperature/2 + 1)
  2. Clean the walls with your wall brush, the waterline with a waterline cleaner (even if it doesn't seem dirty to you).
  3. Check the pH and adjust if necessary (a correct pH is between 6.8 and 7.2).

 

Recommissioning the swimming pool after passive wintering

 

  1. REMOVE EQUIPMENT

  • Winter cover: first, take care to remove any pockets of water and leaves present on the cover or shutter. When removing the cover, it is recommended to do so with several people (at least 2), each placed on one side of the pool. This is to fold it correctly after removing the anchors.
  • Wintering floats (which ensured the protection of the basin)
  • Gizzmos

 

  1. CLEANING THE SURROUNDINGS OF THE POOL: BEACH AND COPINGS

Then clean the beaches and the edges, going from the edges outwards. Using a high-pressure cleaner will help you to remove moss, which can form during the winter. If necessary, scrub the joints.

  1. CHECK THAT THE WATER LEVEL IS AT ¾ OF THE SKIMMERS

 

  1. PREPARE THE TECHNICAL INSTALLATIONS

4.1 Check the electrical box

  • Set the programming clock to summer filtration times
  • Check fuses and contactor

4.2 Restart the filtration system

Pay attention to your pump when restarting it. If it makes an abnormal noise that persists after 1 hour of use, it is certainly because the bearings are seized. They must then be replaced immediately.

 

4.3 Check the sand filter

 

  • CLOSE ALL VALVES (SKIMMER, MAIN DRAIN, VACUUM INLET, 6-WAY VALVE), OPEN THE SAND FILTER LID THEN POUR THE DESCALER INTO THE SAND FILTER (REFER TO THE PRODUCT MANUAL FOR QUANTITIES). THEN, LET IT ACT FOR 24 HOURS WITHOUT REACTIVATING FILTRATION.
  • Do a filter wash and rinse.
  • Restart filtration daily.

 

  1. PREPARE THE POOL WATER

If the water is cloudy, use a flocculant treatment which will increase the efficiency of your sand filter and clarify the water. Then, first check the water balance, meaning the alkalinity (TAC) and then the pH for effective disinfection. The ideal values should be between 12 and 15°f for TAC and 6.8 to 7.2 for pH. To restore your TAC, use a specific alkalinity product, and for pH, add pH minus or pH plus depending on the result obtained. For your information, the pH increases rapidly in the days following recommissioning. Furthermore, if you are using a chlorine treatment, check the stabilizer, which should be a maximum of 30mg/l.

Subsequently, if your water is dirty, we recommend performing a shock treatment (bromine, chlorine, or active oxygen depending on your pool treatment) and following the recommendations indicated on the products for optimal effectiveness.

  1. CLEAN THE POOL

If the winterization was carried out correctly, the water should be clear. However, plant debris may have settled at the bottom of your pool. Use a manual brush to remove them. The pool robot (electric, hydraulic, or other) will then come into play to carry out regular maintenance during the season.
