No matter what happens when the sewer pipes block the property.

The sewer is blocked and the property needs to be managed. Regulations on Property Management Article 36 Property management enterprises shall provide corresponding services in accordance with the stipulations of property service contracts. If the property management enterprise fails to perform the property service contract, causing personal and property safety damage to the owner, it shall bear corresponding legal responsibilities according to law. According to this regulation, there is a prerequisite for the property management enterprise to assume the liability for compensation, that is, it fails to perform its duties as agreed in the property service contract, causing personal injury and property losses to the owner. On the other hand, it is understood that as long as the property has fulfilled its management responsibilities, it will not be responsible for the damage to the owners. If the sewer is blocked, you can first boil a whole pot of boiling water with a hot kettle, then find an abandoned mineral water bottle, pour washing powder, pour vinegar into another bowl to half a bowl, then pour washing powder into the sewer, and then pour half of boiling water. If the effect is not good, pour vinegar and the remaining boiling water. First, mix a proper amount of baking soda with vinegar, dilute it with warm water, and then pour it into the sewer with warm water. In this way, the blockage in the pipeline can be removed, and then the blockage can be washed away with clean water, which is simple and practical.
