What is this black pipe on new lav?
I posted on the Bathroom forum to get ideas for addressing the exposed (and very poorly done) plumbing on my new sink console. Someone there asked me what the black pipe was on the right side, and I have no idea (I had not really even noticed it amidst all the mess). Looks like it is from a dishwasher... Can anyone offer any insight as to what this is and what its purpose would be? I would like to have more information before I go back and talk with the plumber. Thanks in advance!
