Couple of Plumbing Questions

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.
