Is the owner's backwater property responsible?

Look at the location of the blocking point.

The blocking point is your elbow, your own business.

The blocking point is on the straight pipe of this building or the passage from the straight pipe to the main pipeline. The neighboring right thinks that all the owners who use the pipeline above the blocking point, including yourself.

The blocking point lies in the main pipeline, the responsibilities of both parties, the property and the users. For the property, first look at the price level of the contract and the property fee, and see if there is any dredging frequency in the contract. The supervisor (definitely a buried horizontal pipeline) should have a certain dredging frequency, and the pipeline will have an opening, so you can find a professional company to dredge it. If the property is neglected in management, you have certain management responsibilities and can negotiate compensation with the property company. However, it is usually not only your house that is flooded, but also the building in charge of management will have problems. The user's problem is that, except for construction waste falling in during construction, the blocking point of the closed pipeline is caused by the owner's bad use habits, and everything is stuffed in.

If you block the municipal pipeline, you will find municipal compensation. At this time, it will be even more unlucky.
