Can I bend CPVC like I do with PVC (heat gun)
Not that I know of, since you're dealing with heat &amp; pressure &amp; really don't want to screw around with the already somewhat marginal properties of the piping.

Try it at your own peril, but I'd suggest throwing in a 45 or less fitting to accomplish the slight offset. Two 45's (or less) might be needed so you can twist them for the perfect dry-fit &amp; marking before gluing.
