Depending on the height of the ground you live in, it is generally estimated that 0.1 MPa = 10 meters. The terminal supply pressure of the national pipeline network is 0.14Mpa. If you live below ground, the water pressure at the end of the pipe network may increase. So it depends on the floor you live on to determine the water pressure in your home. But if you live in a small building and the tap water is supplied by secondary pressurization, the water pressure at the terminal will be significantly increased. You can ask the property management company to see in what range they regulate the water pressure.
First of all, this is unreasonable.
Your current water pressure is that of the water company. To supply water to the upper stages, a second pressurization is necessary.
There is no secondary pressure. This is a problem with the propertysummer. If such a problem occurs, there should be no ownership.
The solution to this situation is for the community to come together and repair the secondary pressure water pump. The second is to find the local government to resolve the problem.
