I realize cpvc is supposed to be corrosion resistant, however 25 or the IFC does not tie anything back to this section of 13. IFC refers to 25, 25 say's 5-year internal inspections are required without giving a exemption for type of pipe. For the AHJ's on the forum what would you require?

It was added to NFPA 25 at the ROP meeting. Unfortunately the ROP will not be published until June. Until then the approach to take is that the 5 yr inspection is predominately looking for evidence of excessive corrosion activity driven by MIC concerns. As identified by NFPA 13: 23.1.5.2(1), one approach for addressing MIC/unusual corrosion activity is to install corrosion resistant pipe. Since that is defined as acceptable mitigation, why inspect?
