I've recently gone through a kitchen remodel with a wall sink relocated to an island. The contractors did not connect to the original drain, but instead tapped into pipes that were already below the new island location. The pipes they connected to run through the floor and then lead up into the attic, so I can only assume they were for venting the bathroom in the basement below.
My city inspector did not notice this as a problem, but after the kitchen was built, the first time we used the new kitchen sink, it flooded basement bathroom sink below it. I think this was mainly due to the build up of gunk in the pipes (installed in 1969), and after we flushed the kitchen sink a few more times with water, the basement sink stopped flooding.
After some research, I pointed out to our contractor that this probably wasn't done to code (using a vent pipe for draining), but he insists that he can modify the basement sink to prevent future backups (not sure what he is planning) and that it will still drain and vent fine. Just wanted to receive other opinions on if there are modifications that can be made or if I should insist the contractors run the island drain to the old wall location (which would mean cutting into the basement ceiling and a lot more work).
