Def not cast iron, cast iron is used for waste pipes and it’s brittle you could never get threads on cast iron. It’s actually steel even if we call it black iron. A lot of newer houses will run solid pipe from the main to a central location and build a manifold with corrugated steal (flexible pipes) run to the terminal points.
