Listen to the drainage pattern
Record gurgling, slow flow, odor, damp joints, rust-colored deposits, recurring restrictions, or changes when another fixture discharges. Note the floors and fixtures connected as accurately as the property records allow. A symptom at a low fixture may reflect a local branch, stack, venting, building drain, or downstream condition, so the material seen in one room does not locate the cause.
Inspect without striking
Do not hammer, scrape, drill, or pry at an old drain to test it. Photograph accessible manufacturer marks, hub or coupling style, supports, offsets, cleanouts, patches, coatings, and transitions. Ask the plumber whether wall thickness or interior condition can be evaluated at a legitimate opening or with a suitable camera, and what the chosen view cannot establish.
Plan weight and access
A replacement section can be heavy and connected to pipe above or beyond the opening. The scope should identify support before cutting, the removal boundary, new material, approved transition, cleanout access, fire or acoustic assembly, test, and debris route. In an occupied multi-story property, coordinate fixture restrictions and access on the floors that share the line.
Store the camera context
If a camera is used, save the file with entry point, direction, distance or locating method, fixture conditions, and areas the camera could not pass. Pair it with photographs of exposed joints and the final repair. A memorable interior image is not useful when later readers cannot tell which branch, stack, or direction it represents.
