Who is responsible for the replacement of the main pipeline in the old community?

Legal analysis: it should be borne by the pipeline owner. The indoor tap water pipe is your own home. If it's broken, you can only take care of it yourself. The tap water in the residential area of the building belongs to the property and is managed by the property. Outside the community belongs to the municipal pipeline, which is managed by the water supply company. The water supply unit is responsible for the maintenance and replacement of water pipes from the water source to the front of the residential general table. Part of the water pipes from the back of the total water meter in the community to the front of the owner's sub-water meter shall be borne by all the owners. After the owner divides the water meter, some water pipes are repaired and replaced by the owner himself.

Legal basis: Article 942 of the Civil Law of People's Republic of China (PRC) stipulates that the property service provider shall, in accordance with the agreement and the nature of the use of the property, properly repair, maintain, clean, afforest and manage some owners in the property service area, maintain the basic order of the property service area, and take reasonable measures to protect the personal and property safety of the owners.

Property service providers shall take timely and reasonable measures to stop acts that violate laws and regulations such as public security, environmental protection and fire protection in the property service area, report to the relevant administrative departments and assist in handling them.
