Whose responsibility is it that water pipe joints are stuck in tiles?

Legal analysis: according to different reasons, the responsibilities are different: 1. If the main water pipe in the bathroom leaks because of the house decoration, then it is the responsibility of the decoration company or the owner himself. 2. If the main water pipe in the bathroom is not leaking from the decoration company, then the property company is responsible. If the main water pipe of the bathroom is still under warranty at this time, then the property company can ask the developer to help repair it. If it is not within the warranty period, then the property company can only pay for it by itself.

Legal basis: Article 74 of the Building Law of People's Republic of China (PRC), if a construction enterprise cuts corners during construction, uses unqualified building materials, building components and equipment, or commits other acts that are not in accordance with engineering design drawings or construction technical standards, it shall be ordered to make corrections and be fined; If the circumstances are serious, it shall be ordered to suspend business for rectification, lower its qualification level or revoke its qualification certificate; If the quality of a construction project does not meet the prescribed quality standards, it shall be responsible for rework and repair, and compensate for the losses caused thereby; If a crime is constituted, criminal responsibility shall be investigated according to law.
