I looked at that website, Ben, and it appears that PEX is designed for water
systems (presumably, potable water) and it doesn't mention anything about
it's use for sanitation hose. Which brings up two questions in my mind.
The website specifically cautions against using it with any supply "...where
the system contains...ferrous corrodible components..." . Now I'm not sure
whether there are any "ferrous corrodible components" in human waste but it
doesn't sound to me as if its manufactured with any odor containing elements
as marine sanitation hose is.
I'm guessing that if your sanitation system is set up with a fresh water
flush system that wouldn't be too much of an issue, but if not, and you're
flushing with salt water, wouldn’t that be an issue? Even with a
recommendation to give the system a minimum of 10 cycles of the pump handle
after use?
Just curious whether that would be something to think about....

Poor choice for comparison, Skip. The fluid in the soda bottles may fly
in all directions; the polyethylene - what the bottle itself is made of
- just expands out from the point of failure. PVC actually shatters, and
the pieces fly in all directions. Given their mass, they can do, and
have done, serious damage and harm.
*That's* my point. :)
