Ok lets get one thing clear, just so everyone (even flying salt) is sure.
Dwv=bad
PW=good.

If it says nsf-dwv then your gun won't work and you should use it as a combustion or something. Just as a side note, don't use bell reducers use bushings. Reducers aren't pressure rated but it's a common mistake so I'd just like to mention it.
Again DWV on pipe means nothing,

Don't use anything that says cellular core. That means that before being extruded, thousands of tiny air bubbles were whipped into the plastic. this makes it lighter, but it also means it is not safe for pressure.
