The middle floor of a high-rise building, during which the water pressure in the house is unstable, sometimes large and sometimes small, and sometimes there is no water, but there is water at the entrance. What is the reason? Unstable water pressure in the middle layer of high-rise buildings may be caused by the following reasons:

1. The parameters of the water supply equipment control cabinet are not properly adjusted. In this case, the starting frequency of the inverter can be adjusted, and the set pressure can be adjusted to solve the problem of unstable water pressure in high floors.

2. The aging efficiency of water supply equipment is reduced. In this case, it may be necessary to replace the water supply equipment or increase its flow head to meet the water demand of residents during the peak water consumption period.

3. If non-negative pressure water supply equipment is used, the water intake may be less than the actual water consumption of the community, resulting in short-term water shortage of water supply equipment, resulting in unstable water pressure. At this time, the inlet pressure can be increased or a larger negative pressure tank can be replaced (the water pump unit and frequency conversion control cabinet do not need to be replaced).

4. High-rise buildings need variable frequency pumps to supply water through secondary pressurization due to their high floors. During the operation of variable frequency water pump, the water pressure may be unstable due to pressure.

At the peak of water use, for example, when everyone is using water, the water pressure may be unstable.

You can try to report this situation to the property management company and see if it can be alleviated by increasing the pressure or replacing the pressurization device. If it cannot be solved, it is recommended to seek professional help.
