Don,
That's where the code says it has to drain to anyway if there is not a 'floor drain' (my term, not stated in the code that way, but that's about all it can be) there to drain into.
From the 2006 IRC.
- P2801.5.2 Pan drain termination.
The pan drain shall extend full-size and terminate over a suitably located indirect waste receptor or shall extend to the exterior of the building and terminate not less than 6 inches (152 mm) and not more than 24 inches (610 mm) above the adjacent ground surface.
