How much water pressure is needed for secondary pressurization of high-rise buildings? What if the water pressure is insufficient?

Many houses are high-rise buildings now. Because of the limited land in the city, the higher the house is built, the better it is to live in a high-rise building. But at the same time, there is a serious problem, that is, the water pressure of high-rise buildings is not good, and many people can only supply water to residents normally through secondary pressurization. So let's know what is the secondary pressurization water pressure regulation of 20 18 high-rise building? What if the water pressure is insufficient?

20 18 What are the regulations for secondary pressurized water pressure of high-rise buildings?

In general, high-rise residential buildings can be divided into low areas, middle areas and high areas, and the height between the areas should not be too high. The higher the floor between areas, the greater the pressure, which is prone to problems such as tube explosion. In reality, each area is about 10 floor, depending on the actual situation.

High-rise residential secondary pressurized zoning water supply shall meet the following requirements:

1, high-rise residential water supply system should be vertical partition, vertical partition pressure should meet the following requirements:

2. The hydrostatic pressure of low partition sanitary ware distribution point should not be greater than 0.45MPa；;

3, when the static water pressure is greater than 0.35MPa, household pipes (or water distribution pipes), appropriate decompression or pressure regulating facilities;

4. The water pressure of unfavorable water distribution points in each partition should meet the water pressure requirements.

5. The water supply pressure of household pipes in residential buildings should not be greater than 0.35MPa.

6. For the domestic water supply system of buildings with a building height of less than 100m, the water supply mode of vertical partition parallel connection or partition decompression should be adopted; For buildings whose building height exceeds 100m, vertical series water supply should be adopted.

What if the water pressure is insufficient?

1, the first thing we need to do is to report the problem to the property management company. If the property management company does not handle it, we can reflect the problem to the tap water formula, and at the same time, we can also reflect the problem to the neighborhood Committee, community and relevant government departments, which will eventually be completely solved. At this point, the pump house and pipeline need to be completely upgraded;

In addition, we can take some measures to deal with it ourselves. The easiest way is to install a booster pump, which is easy to buy We can buy one ourselves and install it on the main water pipe at home. In addition, remember to install a check valve at the outlet of the circulating pump as much as possible, which can also solve the problem of insufficient water pressure to some extent.

3. In addition, we can also adopt the method of installing small water storage tank and booster pump, which is an upgrading method that only installing booster pump can not solve the problem. This method needs to occupy a certain space. Everyone should know this. The solution is to install a water storage tank to ensure the water consumption, and then use a booster pump to ensure the water pressure during use. This installation method also needs to be equipped with components such as check valves.
