Answer 2

I too have a dual kitchen sink with garbage disposal.  What is sounds like is there is still a clogg some place.  A garbage disposal requires such a force to push what its grinding up that the water has to rush really, really fast.  The only thing I can think of right now is a product called roebic.  It has a product that can clean lines out.  The other thing I would do is take a good look at your garbage disposal.  It doesn't sound too effective if it isn't chewing things up.
