I'm working with some CPVC for hot water and now I need to make some adjust for better placement. With PVC I would just heat a bit to remove any possible stress or to put it into a more adequate position, can the same be done with CPVC?
Not that I know of, since you're dealing with heat & pressure & 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 & marking before gluing.
