Abstract: A method for certifying the compliance, building specifications, and/or integrity of a plumbing system including water supply; ground/storm water; and, sewage/drainage systems servicing a building, house or other structure involves ascertaining the updated pluming codes and regulations and/or the updated construction plans which pertain to such system, inspecting the system and reporting the compliance and/or integrity of the system. In one aspect the inspection involves captured video tracings of the system with accompanying data including grade, a mapping of the line location, sizing, branching and breaches of integrity. An inspection device adapted to fit within the lateral branch as well as traverse drains to an appliance and vents is utilized.
