Where must an air-conditioning condensate drain line discharge?
Not quite. The answer is C: To an approved plumbing fixture or disposal area; if it enters the drainage system, it must do so through an indirect waste pipe
Condensate from air-cooling coils and condensing appliances has to be collected and delivered to an approved plumbing fixture or disposal area, and where it goes into the drainage system it must enter through an indirect waste pipe sloped at least 1/8 inch per foot. A rigid direct connection would give sewer gas a path back into the equipment and the occupied space, and condensate may not drain over a public way.
