Who is responsible for the leakage of the house downspout?

Legal analysis: the property management company has the responsibility to repair the water leakage of the domestic sewer pipe, but the maintenance cost should be borne by the owner. First of all, it is necessary to distinguish whether the leaking pipeline is a public pipeline. If it is a public pipeline, the maintenance cost should be borne by the property management company, and if it is used by the owner, the maintenance cost should be borne by the owner.

Legal basis: Article 712 of the Civil Law of People's Republic of China (PRC), the lessor shall perform the maintenance obligations of the leased property, unless otherwise agreed by the parties.

Article 713 Where the lease item needs maintenance, the lessee may require the lessor to maintain it within a reasonable period of time. If the lessor fails to perform the maintenance obligation, the lessee can carry out the maintenance by himself, and the maintenance expenses shall be borne by the lessor. If the maintenance of the leased property affects the lessee's use, the rent shall be reduced or the lease term shall be extended accordingly. If the lease item needs maintenance due to the fault of the lessee, the lessor shall not undertake the maintenance obligation specified in the preceding paragraph.

Article 714 The lessee shall take good care of the lease item, and shall be liable for compensation if the lease item is damaged or lost due to improper care.
