Ductile iron pipe and concrete?

(Disclaimer: Not an expert at all, so could be totally wrong... but I remember those terms from many moons ago when I worked on an M&A deck for some American pipe company that hated competition from Chinese PVC pipe manufacturers. Not a fun project)

Ugh, no screwpipe, that was a 1950s housing boom compromise that should never be repeated!

First person to suggest Orangeburg gets to dig up 100 feet of collapsed lateral in winter.

Given the asbestos content, that's not really an option anyway, yeah?

The real low quality stuff was just wood fibers and coal tar, IIRC!
