Reconfiguring waste pipe in tight space
This is the waste pipe from my kitchen, coming down through the basement ceiling at the outside wall, joined to an iron pipe which turns away from the house to an old buried main line. The main line is in bad shape, so we'd like to redirect the kitchen waste to a modern main line in the basement.
Do you see any way to make the required changes, including capping off the iron pipe, in the available space? My plumber thinks it's too tight.
