The answer is yes to the question. The specific, more restrictive requirements of FBC, Building 456 take precedent over the general requirements of FBC, Plumbing 403.3. See FBC, Building section 102, Where there is a conflict between a general requirement and a specific requirement, the specific requirement shall be applicable. Where, in any specific case, different sections of this code specify different materials, methods of construction or other requirements, the most restrictive shall govern.
