Where do plumbers usually install rough piping?

Plumbers typically install rough piping within the walls, floors, and roofs of a building. This installation method is essential for ensuring that the plumbing system is integrated seamlessly into the structure, allowing for both functional and aesthetic considerations. By placing pipes within the walls and floors, plumbers can effectively conceal them from view, thereby enhancing the visual appeal of the space while protecting the pipes from potential damage or exposure. Furthermore, this placement facilitates easier access for maintenance and repairs, as the infrastructure is designed to allow for the necessary access points.

In contrast, options like installing pipes above ground, outside the building, or in underground reservoirs do not reflect standard plumbing practices for rough installations, as these locations often do not provide the required protection, accessibility, or alignment with building codes and regulations.
