How many years is the shelf life of residential water pipe network?

Generally speaking, the water pipe network must conform to the construction specifications, and the engineering life is 40 years. But it depends. First, the reconstruction of the husband's house is the responsibility of the construction unit that has problems within 1 year. Second, if it is a new community, it can be divided into two types. If it is not handed over to the property management, then whenever something goes wrong, the director will be responsible; If it has been handed over to the property management, the shelf life of the pipe network will be determined according to the construction standards and materials, and problems will be handled with the community maintenance fund. In addition, if it is the raw material problem of the pipe network, it can be sent to the quality inspection unit for inspection and claim.
