Yes, as Greg so eloquently stated the FOP test up here is around $500.00, and the one that I know of failed the testing brutally. Arguing with me, or any other inspector is really not a good thing. Healthy discussion is fine and appreciated.
IMHO, two (2) rods are what the code states. Up here the the water mains are plastic for at least 80% or more. UFER s are installed when it's new work. Others are 2 rods, and another code compliant choice, plate, etc.
It looks like metalic water piping is going to join the other relics, like knob & tube!
