You need to find someone to clear the pipe, and find the person in charge based on the pipeline design.

It is normal for sewer pipes to become clogged after being used for a long time. However, the cause of the clog must be found and repaired in time to avoid affecting normal use in the future.

If the sewer on the first or second floor is blocked, the upstairs is responsible. This depends on the design of the house. If the sewer drains separately, then the upstairs does not need to bear any responsibility. The sewer pipe is for private use, and if the cause of the blockage cannot be found, the people upstairs and downstairs are both responsible. However, if the blockage is between the main pipe and the first floor, the people upstairs are not responsible.

Pipeline design in old communities

When designing buildings in old communities, generally the houses on the second floor and above use one pipe, while the houses on the first floor use one pipe. Since it is too close to the manhole, a separate pipe is used to prevent overflowing odor. The first floor of a high-rise building must be drained separately. The reason for this design is to take into account the water pressure on the bottom layer.

If water is flushed from the second floor to the top floor at the same time, and a straight pipe is drained down, the pressure will increase as you go down, and blockage will easily occur. The first floor is connected separately, so the drainage pressure will naturally be on the second floor. However, most new houses now have water pressure measurements, and if the floors are higher, the second floor may also be taken over separately.
