Could PEX (cross linked polyethylene) fill the gap? It’s already used in residential. Plus more flexible than PVC

Flexible is bad for drains, you get sagging leading to water pooling the pipe.

My impression is PEX is the standard for modern plumbing, but I don't know about drains specifically. Maybe we will find it also has issues, but it seems like every modern material has externalities.

Pex is used in water supply, not drain and vent.

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!

ABS pipe?

Soldered DWV copper is also acceptable :P Doubt we'll be going back to wiped lead...

It's a 10ft drain pipe, Michael. What could it cost? $500?

Probably basalt-lined pipe.
