Regarding the leakage of the main sewer pipe in the kitchen at home, the owner asked for property maintenance. ^_^

The first thing to look at is the location of the leak. If the location of water leakage is outside the external wall, it must be a public area and unconditional property maintenance; If it's not outside the exterior wall, it depends on which floor you live on. If there are no other residents below you (for example, the first floor or the second floor is overhead), the leaking part is below the floor, which is also the unconditional maintenance of the property, and you are responsible for other situations.
