Basically NO PIPE OF ANY TYPE should be directly embedded in a concrete foundation wall. This includes cast iron and plastic drainpipes…Such pipes should pass through the wall inside of a box or sleeve (you can make your own or used items manufactured for this purpose.. Besides the problem of chemical reaction between the concrete and the pipe, there is the problem of differential movement of the two, from settlement or earthquakes.

Nope, I haven’t checked out that email list, but maybe I should…
Hey, I’m just a dumb plumber. I’ve got no special knowledge. I apprenticed with this old German guy, Otto, when I was starting out. I read a bit, and keep up on the UPC and local codes. It’s all common sense and experience “in the trenches.” I’m just a Journeyman. Not a real Master Plumber.
