I would just go ahead and re-do the drain. Was it sealed at the factory??? It's supposed to be, but it depends on the brain surgon who installed it, and his level of compentancy, as to weather or not it was done.
In your shoes, I would recheck all drains, and all the water connections to make sure their installed (re...not cross threaded) and tight.
