When discussing pipe fittings, what is a "run" typically associated with?

In plumbing terminology, a "run" is generally associated with the length of straight pipe used to connect two points within a plumbing system. This term is especially relevant when discussing horizontal runs, which are common in drainage and water supply applications. Horizontal runs are typically measured parallel to the ground, which is essential for ensuring proper drainage slopes and preventing issues like water pooling or improper flow.

While vertical measurements and diagonal measurements are important in plumbing, they are not specifically referred to as "runs." The focus of the term "run" is primarily on length, and when used in context, it often implies the horizontal orientation of that length. This is significant for design planning, installation processes, and ensuring compliance with building codes related to pipe installation and drainage. Understanding this concept is crucial for anyone working in plumbing to ensure effective and efficient system design and implementation.
