Which section provides definitions of terms related to plumbing, specifically related to storeys?

The section that provides definitions of terms specifically related to plumbing in the context of storeys is indeed focused on plumbing terminology. This section is crucial because it clarifies how "storey" is interpreted within plumbing-related scenarios, including the installation and design considerations that vary with different storey levels. Understanding these definitions helps plumbing professionals ensure compliance with regulations and standards that pertain to multi-storey buildings.

The other options address different aspects of plumbing but do not specifically tie the terminology back to storeys. Definitions for Water Supply and Definitions for Drainage pertain more to specific systems or mechanisms rather than the context of storeys. Definitions related to sanitation would cover sanitary facilities and their requirements but not necessarily plumbing definitions associated with various storeys in buildings. Therefore, the focus on plumbing terminology connected explicitly to storeys makes this section particularly relevant for professionals dealing with plumbing design and installation in multi-storey structures.
