What is it?

Water heater was my guess the second I saw those pics. Very common to be in the attic out of the way but no way I'd want to lug that up there.

Reminds me of the attic-installed AC/heat unit at my dad's old house. PVC condensate drain, copper lines to the compressor / condenser unit.

CPVC does get brittle with age but is not an issue if it is undisturbed. When working on a CPVC system, be careful not to move any existing pipe that will remain, and use an appropriate tool to cut old pipe (i.e. not shears). Occasionally you might run into CPVC fire sprinkler pipe that is distinctly orange in color. PVC will be white and CPVC more beige.

The sheers worked on the first two cuts, but the pipe that goes down through the ceiling was too brittle for the sheers, had to use a hack saw. Seeing how brutal it was makes me want to **** myself when I turn the water back on lol letting it sit for 24 hours before I turn it on. Hopefully I didn’t break anything else while repairing that.

Right! If it were me, I would have cut it below the joist and glued on a cap.
I mean I would prefer it all be copper, but when builders build whole communities at once, they tend to go cheap.
In reality I believe this whole community had that gray pipe originally.
Im pretty sure this CPVC/PVC was put later to replace the gray ****.

Is that even possible? CPVC uses CTS dimensions whereas PVC uses IPS.

I believe I read somewhere that CPVC can be bought in either.

By the way, I turned on the water today and all was good.
