Our plumber/handyman, a friend of a friend named Shawn, came about 9:45am and finished just shy of 5pm today. He took out the old plumbing from the previous sink location and put all new plumbing in the new location with, of course, the proper venting through the roof which we were previously missing. This would have taken us days, including a lot of head scratching, so I am thankful it is over and done (sans the dishwasher but we need to pinpoint the precise location and he claims that will idiotproof).
