Which abbreviation refers to plumbing drawings?

The abbreviation that refers to plumbing drawings is "P Drawing." This designation is commonly used in architectural and engineering documents to represent plans, details, and layouts specifically for plumbing systems. Such drawings illustrate the piping, fixtures, and equipment related to water supply and drainage systems in buildings.

In contrast, other abbreviations serve different purposes within construction documentation. For instance, "FP Drawing" typically refers to fire protection drawings, which detail systems designed to manage fire hazards. "M Drawing" often denotes mechanical drawings, which cover HVAC and other mechanical systems, while "S Drawing" is associated with structural drawings, illustrating the framework and structural components of a building. Each of these abbreviations has its distinct relevance, but for plumbing specifically, "P Drawing" is the standard designation.
