So what are we going to use for Drain-Waste-Vent plumbing? Go back to cast iron with oakum and lead?
- airstrike 3y agoDuctile 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)
- systems_glitch 3y agoUgh, 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.
- Sindisil 3y agoGiven the asbestos content, that's not really an option anyway, yeah?
- systems_glitch 3y agoThe real low quality stuff was just wood fibers and coal tar, IIRC!
- xyst 3y agoCould PEX (cross linked polyethylene) fill the gap? It’s already used in residential. Plus more flexible than PVC
- ars 3y agoFlexible is bad for drains, you get sagging leading to water pooling the pipe.
- jwagenet 3y agoMy 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.
- throwaway4aday 3y agoPex is used in water supply, not drain and vent.
- a_gnostic 3y agoProbably basalt-lined pipe.

- systems_glitch 3y agoSoldered DWV copper is also acceptable :P Doubt we'll be going back to wiped lead...
- throwaway4aday 3y agoIt's a 10ft drain pipe, Michael. What could it cost? $500?
- 14u2c 3y agoABS pipe?
