My family lives on 18 floor. I came home yesterday and found the whole house flooded, all the way to my room, and then I looked for it.

In order to save trouble, most careless decoration personnel directly pour waste paint, coating and cement slag into the sewer pipe. All the settled heavy objects are deposited in the pipeline. It is easy to cause pipeline blockage.

Let the property coordinate from it. If it is determined that the decoration materials are blocked, find the responsible party.

Part of it should be shared by all households who use the pipeline unless they can prove that they are not responsible.

But the property company has the responsibility to supervise the decoration.

Some homeowners have the responsibility to maintain it, and whoever causes losses will compensate for it.

I hope to give you a reference.
