There are various specifications and models of swimming pool filter sand tanks. Therefore, the specifications selected for different sizes of swimming pools are not the same. Generally, regular swimming places will have a circulating filtration system, and the owners rarely change the water during the swimming season. The system replenishes water to ensure pool water, and the daily cycle must be turned on for at least 6-8 hours. At this time, we need to backwash to ensure the filtering effect of the sand tank. When is the most suitable time for backwashing and precautions: 1. If the pressure gauge reading on the filter sand tank is higher than 2.5kg or above, you need to immediately check Backwash the filter sand tank; 2. Confirm that the relevant water pumps that need to backwash the sand tank have stopped running; 3. Adjust the multi-directional valve on the filter sand tank to the backwash (Backwash) state; 4. Run the water pump first; check and Observe the clear water mirror on the sand tank until the water is clean; then turn off the water pump. 5. If the backwash water cannot be checked, the backwash time is generally 3-5 minutes.
(Generally 2-3 times a month, such as once a week in peak season) 6. After backwashing, turn off the water pump, adjust the multi-way valve to (RINSE) rinsing state, then turn on the water pump to run for 1-2 minutes and then turn off the water pump That's it.
