Who will pay for the leaking wall of the main pipeline?

Legal analysis: this issue should be analyzed in detail. See if the water pipe is under warranty first. Usually the warranty period is 2 years. If it is within the warranty period, the developer is responsible. Secondly, see whether the water pipe rupture is a quality problem or a natural damage. If it is a quality problem, the water pipe supplier should also bear the responsibility. Pipeline leakage is a natural damage, and the expenses incurred are maintained by the special maintenance fund for property startup.

Legal basis: Article 51 of the Regulations on Property Management in People's Republic of China (PRC), water supply, power supply, gas supply, heating, communication, cable television and other units are responsible for the maintenance and conservation of relevant pipelines, facilities and equipment within the property management area according to law. If the units specified in the preceding paragraph temporarily occupy or dig roads and sites due to maintenance, they shall promptly restore the original state.
