The sewer of the whole building was blocked, which caused the houses on the first floor of my house to be flooded. How should the property be compensated?

Hello, according to what you said, the residential property should be liable for compensation. There are two reasons for taking responsibility: first, you were not informed to come back in time to protect the house finances from unnecessary losses; Second, the property did not patrol in time to find that the sewer was blocked, and it was cleared in time to eliminate the disturbance. Therefore, you can claim damages from the residential property according to law. If the property refuses, you can go directly to the court and claim compensation according to law. Thank you.
