Who is in charge of the high-rise sewage main pipeline?

Legal analysis: the property is responsible for the high-rise sewage main pipeline. If the householder's sewer is blocked by the manhole sewer supervisor outside the building, the property must be maintained and managed in accordance with the contract, and the owner has the right to pursue the responsibility of the property. If it is true that other users downstairs have modified their own sewer pipes without authorization, resulting in frequent recoil of the sewer pipes, then the downstairs owners should bear the main responsibility for this.

Legal basis: Article 35 of the Regulations on Property Management, a property service enterprise shall provide corresponding services in accordance with the stipulations of the property service contract. The realty service enterprise fails to perform the realty service contract, causing personal and property safety damage to the owner, and shall bear corresponding legal responsibilities according to law.
