you will want to move that copper DWV piping in the wall.
Without seeing behind the drywall, it may be horizontal back there, or coming up vertical. It makes a difference which way it has been done before.
Before I hire a plumber and pay him $75 for a service call just to tell me what can or cannot be done, please give me some guidance. I am in the process of a kitchen remodel and would like to move my sink setup about 30-40" to the left from the pictures below. Where the sink is now, will be a dishwasher, so I am concerned about the pipes hitting and the dishwasher not sitting flush on the back wall.
My main question is what is the cheapest and most effective way to move the sink piping? Extensions etc? I need something detailed so that I can talk to my friend about it who has plumbing knowledge. Thanks for your help guys.
It's hard to give an exact estimate looking at pictures which don't show inside the wall. You need to get a plumber or two down there. Most plumbers will cut the wall, but won't repair it after they're done with the pipes.
I don't even start my truck for $75.00 an hour, so my "rough" estimate would be a lot more than your $75.00/hour plumber would charge, assuming I knew what was inside the wall so I would know how it can be done.
