Couple of Plumbing Questions

[St Albert Reefer]

I would like to construct a spray / dispersion bar for my nano on closed loop using a submersible micro pump. But I'm having a difficult time finding CPVC pipe and fittings in Edmonton. Where can I purchase this pipe? (1/2 inch diameter)

Also is CPVC available in grey? If not, can anyone suggest a SAFE paint I could use? Thanks

Revy down here seems to have CPVC parts, if that helps.

Any reason you want to go CPVC over normal PVC? I made my spray bar using a maxijet 1200 powerhead and white 1/2" PVC. The tubing that fits over the output of that powerhead has an outside diameter of 1/2", so it nicely jams into a piece of 1/2" PVC and seals up pretty good without messing about with bushings or barb fittings or whatnot.
