Sounds like he's saying it's a metal water pipe electrode... :happyyes:I had to bond to a pex system once. :blink: I looked at the inspector and said, you know it's not metal, right? Yeah, he says, but it's connected to a copper pipe that goes into the ground. :huh:
<20' of #4 and a j-jr or a battle with an inspector...
A lot of people think the electrode rules only apply to the incoming water pipe, but it applies to outgoing metal water pipes too.
