Why is the sewer on the second floor always blocked? Is there any way to solve it? If it is repaired, will it be shared upstairs and downstairs?

Need to find someone to dredge, according to the pipeline design to find the main person in charge.

It is normal for sewer pipes to be blocked for a long time, but it is necessary to find out the cause of the blockage and repair it in time so as not to affect the normal use in the future.

The sewers on the first and second floors are blocked, and the upstairs is responsible. It depends on the design of the house. If the sewer drains alone, then the upstairs is not responsible. The sewer pipe is used for * * *, so the upstairs and downstairs are responsible for the blockage, but the blockage is between the supervisor and the first floor, so the upstairs is not responsible.

Pipeline design of old residential area

In the design of old residential areas and buildings, the houses on the second floor and above are generally single-pipe, while the houses on the first floor are too close to the manhole, so separate pipes are used to prevent odor. The first floor of a high-rise building must be drained separately. The reason for this design is to consider the water pressure at the bottom.

If all floors from the second floor to the top floor are flushed at the same time, and a straight pipe is discharged, the downward pressure will be greater, which is easy to cause blockage. The first floor is taken over separately, so the pressure of this drainage is naturally on the second floor. However, most new houses are now measured by water pressure. If the floor is higher, the second floor may also be taken over separately.
