I'm doing a bunch of ABS plumbing for the first time. I have everything cut and ready to assemble so do one last YouTube search for a few tutorials on glueing.
Seems really simple.
HOWEVER, all the tutorials are using this yellow cement. The one I have is black. It's labeled "Medium Black ABS Cement". Is this the right stuff and just a different color? Or do I need to make the road trip back to Home Depot to find the yellow stuff?
It's ABS cement, you should be fine.
IIRC, the "yellow stuff" is the typical multi-plastic version that's somewhat more commonly found (IMPE) and can join ABS, PVC, CPVC, or any mixture of them - around this area, ABS is rarely seen other than already installed in old installations, so the yellow stuff is more useful to folks who need to repair or adapt it with PVC parts.
ABS piping produces more noxious fumes when it catches fire than PVC does.
For most new multi-family dwellings ABS is not even permitted for that same reason.
The Yellow "Stuff" is not a multi plastic cement, it is meant solely for ABS and the reason it is yellow is so that you can tell the joint has been properly glued.
The Black is more for aesthetics than anything.
