Do you need to bear legal responsibility for blocking the door of the community because of property conflicts?

The location and causes of sewer blockage are as follows: 1, within the outline of personal residence, the blockage is responsible for itself; 2. Outside the outline of individual residence and inside the red line of residence, the property is responsible; 3 residential areas outside the red line, the municipal government is responsible for. If the specific reasons for the blockage are found in the cleaning process, the relevant responsible person shall be responsible. At present, property companies can generally provide pipeline dredging services, but may need to charge. My personal view on this matter is to get through it quickly and don't feel bad.
