Backwash โหมดการล้างย้อน เพื่อล้างหน้าทรายให้สะอาดอยู่เสมอทำงานอย่างไร? การไหลของน้ำเป็นอย่างไร? สูบน้ำจากไหน? คลิปนี้มีคำตอบ

The New Year holiday is a time when many families travel to other provinces or overseas, leaving their homes unoccupied for several days. For homeowners with swimming pools, this often leads to concerns that the water may turn green, develop unpleasant odors, or require costly cleaning and water replacement upon return. In reality, closing a swimming pool for 7–10 days is not difficult if the correct water care principles are applied. The key is proper water preparation before leaving, using the right chemicals to work in place of daily maintenance. This approach helps control algae growth, bacteria, and the accumulation of dirt during periods when the pool is not in use. This one-time, 10-day pool care method is designed for residential pools and can be applied to both homes without automatic control systems and those equipped with Smart Home or Smart App monitoring. It allows pool owners to reduce system operation while still maintaining stable water quality throughout the holiday period. When chemicals are selected correctly and adjusted according to pool size, homeowners can return from their trip to find clear, clean water. With minimal effort—such as vacuuming settled debris—the pool is ready for immediate use, eliminating the need for draining or refilling and ensuring a stress-free return home.

Hydrochloric acid 35% or hydrochloric acid or Hcl 35% is used for cleaning the pool floor, concrete floor, water treatment, and pH of the pool. Dosage: 3 liters per 100 cubic meters of water when the pH exceeds the standard range of 7.2-7.6.

Kindly perform the following checks: Ensure that the pool circulation pump is operating. Verify that all relevant valves are fully open. Clean the pump strainer basket and the skimmer basket. Release any trapped air from the pump housing. Inspect the flow sensor to confirm that it is clean and unobstructed. If the issue persists after completing these steps, please inform us and we will arrange for a technician to conduct a detailed inspection. Thank you."**
