Who is responsible for scrapping the integrated ceiling due to water leakage from the upper and lower pipes?

Three situations: water pipe installers or integrated ceiling personnel are responsible during the warranty period, and users are responsible outside the warranty period;

During the warranty period, the water pipe construction party is the main person in charge, and the water pipe installation company shall be responsible for the failure of the integrated ceiling personnel to replace or reinstall the water pipe;

During the warranty period, the integrated ceiling construction personnel are responsible for the secondary construction of water pipes;

During the survey, the personnel of both construction parties must have the construction qualification certificate or qualification certificate of relevant industries before they can take up their posts;

Even during the warranty period, users have to bear secondary responsibilities. All household appliances have a certain degree of potential hazards, and users need to find and control them in time to be truly safe.
