Until now, secondary pressurization fees for tap water need to be collected by property management points in each community, and the pricing situation is different in different communities.
Currently, secondary pressurization fees are only charged to residents on the 7th floor and above. If the house is located below the 18th floor, try to choose water supply equipment without towers and negative pressure. This will occupy a smaller area, generally will not cause secondary pollution, save electricity, and have relatively low operating costs.
Generally, those above the 18th floor use a variable frequency constant pressure water supply, and those below the 18th floor use a water supply without turns and negative pressure. Constant pressure mainly requires adding reserveswater towers for water towers. upstream and downstream water supply, and the non-negative pressure method is directly connected to the tap water pipe network to provide downstream water supply.
The size of the second choice of pressure water supply equipment depends on the population of residents. If there are a large number of people and the water consumption is relatively large, a larger one should be selected. the number of inhabitants is low, a small one will be enough. In addition, you should choose the appropriate water supply equipment and the size of the installation place based on the height of the building and your own economic conditions.
