Regardless of which cement you use, remember to clean the pipe and
fitting first with the purple "primer".

Why purple primer?

Obviously, the color doesn't matter, but around here (WA state) the purple
primer is what you typically find in the home centers. I haven't seen clear
primer in years.

PVC/CPVC primer is usually purple.
CPVC cement is usually orange.
PVC cement is usually clear (or blue).
ABS cement is usually black.

The color primarily lets you (and the inspector) see at a glance what type
of glue was used and whether or not the primer was used.
