Reply To: How do I attach new plumbing to old lead drain?

I take it that the basement floor is concrete.My guess is that there is a cast iron hub not far below the concrete that the lead connects to.Might be worth it to chisel away some of the floor to see if there is cast iron and go from it with a new line.You could also use a nipple the same size as the lead and fasten it to the lead line with a fiberglass repair kit that is used to patch fiberglass boats.I have done this more than once with good results.The lead has to be cleaneds does the nipple.I would try to find a cast iron hub first though.Good luck
