Default Corrosion/Erosion of metallic fixtures & copper piping

We re-piped a high rise in Austin about 13 years ago with CPVC (Flowguard Gold). The new piping system has performed very well. We have had 6 leaks over the years in the miles of pipe installed. The majority of these leaks were installation problems, such as inadequate provision for pipe expansion.
What we have been seeing lately is the failure of PRV's, valves and other metallic devices. Often a green crusty build up is present on the exterior of such devises. The copper piping in the mechanical room is starting to develop pinhole leaks. Corrosion/erosion is the suspected culprit. The only change to the system was a new water softener was installed to replace the existing approximately two years ago. The problems started to show up frequently thereafter.
Austin, Texas is said to have aggressive water. This was tested and the PH was within limits.
Does anyone have an insight on this problem, or experienced a similar situation?
