Kerdi drain with cast iron drain pipe?
I have a 2-family home in Brooklyn, NY, and I want to renovate the basement. Full gut, moving of plumbing, etc. The basement currently has a small bathroom with a tub, and I want to replace this with a walk-in shower. I am interested in using the Kerdi shower system for this renovation. However, to my knowledge, all our drainage pipes are cast iron (according to NYC plumbing code).
Has anyone successfully installed a Kerdi drain coupled with a cast iron drainage pipe? Is doing so ill-advised?
