Whose maintenance belongs to the leakage of toilet sewage pipe?

Generally speaking, the sewage pipe in the bathroom is a part of the pipeline system of the house, and the maintenance generally needs to be undertaken by the owner or lessee of the house. If it is the drainage system of public toilets or apartment buildings, it may need to be maintained by property management companies or relevant management departments. It is suggested that you contact the property or landlord first to understand the specific situation and handle it according to the relevant regulations.
