The main pipeline blocked the second floor. Whose responsibility is it?

It's really heartbreaking that the main water pipe is blocked, causing the sewer at home to pour water. What about the "reverse water" in the sewer? Who will bear the responsibility? Xiaobian of China Travel Service. Com has compiled relevant legal knowledge. Please read the following article to understand. The sewer is against the current, and the property does not match Ms. Xiong's house. After the sewer overflowed, she contacted professional maintenance personnel for home repair at the first time. After checking the pipeline, the maintenance personnel found that the cause of water leakage was the blockage of the manhole sewer pipe supervisor in the building. Even if it is repaired this time, it may still be blocked after a while. After learning this situation, Ms. Xiong immediately reflected the situation to the residential property management office. After inspection by the property staff, Ms. Xiong lived on the second floor. The residents on the first floor of the building have recently reconstructed the sewer pipes originally used by the residents on the ninth floor upstairs, and increased the connection between the pipes and the sewers outside the building, resulting in the sewer upstairs being easily blocked and the sewer in Ms. Xiong's kitchen overflowing. The property said that Ms. Xiong should negotiate with the owners downstairs and the property should not bear the relevant responsibilities. Because the property did not cooperate during the Spring Festival and the maintenance personnel were not in place, the overflow problem of Ms. Xiong's kitchen sewer pipe has not been repaired. Until today, as long as the displacement of the upstairs residents is large, the sewer pipe in Ms. Xiong's kitchen will overflow, and the family is very depressed. Ms. Xiong said inexplicably: "The property contract stipulates that property management services include the maintenance, management and operation of public facilities and equipment. Public facilities and equipment refer to sewers, downpipes, pools, gas supply pipelines, power supply pipelines, garbage stations (houses), manholes, septic tanks, etc. But now the property refuses to provide corresponding services on the grounds that the residents on the first floor replace the sewers themselves. We can only find maintenance personnel at our own expense to dredge the pipes and temporarily solve the problem of recoil of kitchen sewer pipes, but this is not the solution to the problem. Who should be responsible for this situation? " Legal interpretation of sewer "anti-water" who will bear the responsibility? According to the relevant regulations of property management, since Ms. Xiong has paid the relevant property fees, the property management company should fulfill the responsibilities and obligations of maintaining the public facilities in the community in accordance with the contract, and can't find any reason to shirk. In this case, if Ms. Xiong's sewer is blocked by the manhole sewer supervisor outside the building, because it belongs to the community public facilities, the property must be maintained and managed in accordance with the contract, and the owner has the right to investigate the responsibility of the property. The owner shall be responsible for changing the sewer pipe without authorization. If it is true that the owner on the first floor modified his own sewer pipe without authorization, and the sewer pipe of Ms. Xiong's house on the second floor often appears recoil phenomenon, then the owner on the first floor should bear the main responsibility for this. It is never a solution to find someone to dredge Ms. Xiong's sewer when it is blocked. On the one hand, it is suggested that Ms. Xiong communicate with the upstairs residents and ask them not to throw domestic garbage into the sewer again. On the other hand, the owner on the first floor is required to restore the sewer to its original state and fundamentally eliminate the fault.
