1. The pipes and sanitary ware are blocked, and the tap water contains a lot of impurities. After a long time, the pipes will inevitably be blocked, resulting in low water pressure.
2. The floors are high and the water pressure is low. High-rise buildings all use secondary water supply. During the peak water consumption period, the water pressure becomes low, resulting in a small water flow.
3. The complexity of the water pipeline is caused by the large number of elbows, joints or valves in the water pipe, resulting in a decrease in the water pressure.
