Giải thích
A cleanout is required at or near the junction of the building drain and the building sewer, commonly installed as an accessible two-way cleanout, to allow rodding in both directions. Individual fixture traps and roof vents are not the required junction cleanout location, and an exterior cleanout is exactly what this rule provides.
