An air conditioning unit sits on an equipment pad with a drain pan discharging condensate through a trap and vent assembly. A three-inch waste line from restroom one with a trap and vent runs below the roof at a one percent minimum slope. A vent extends up through the roof, with its exact location coordinated per the floor plan. The condensate line discharges into a roof receptor with a minimum one-inch clearance.
