Hiya,

Im a bit useless when it comes to anything like this, so please accept my apologies for my lack of knowledge!

Right, I want to move my sink in my kitchen to the other end of the kitchen and onto a different wall. It will still be on the outside wall, yet it is too far to run a waste pipe from the new location of the sink to the old drain (plus it is round the corner). So I need to make another drain in the ground coming from the old one under the ground. Id basically like to know where to start! How do I go about doing this? Or is it best to get the proper people in to do it? Plus do I need to add it to my buildings control form when I tell the council Im putting a new window in? Kindest regards, Laura.

Hi Laura,

What you are planing is major surgery and unless you have plumbing skills and tools it's best left to a professional. You would have to run a vent as well as a new drain line plus repositioning the supplies. You didn't say but if you're on a slab the floor would have to jackhammered up to move the drainage.
If this is a condo you will have to get permission for such a extensive remodel.
Good luck, Tom
