Good point, are you using gas or electric? Edit:Never mind, I type too slow!
I would think you would want to actually "connect" the duct to the sinks drain hole. That way you would be forcing the discharge down the drain and into the sewer (as long as there is not too much back pressure). Then just run the tap afterwards to fill the s-pipe up again.
