Scott:

I do understand the difference between bonding and grounding (mostly); the differences between PVC, CPV and PEX as well (certainly not a the molecular level or anything). My concern here was that the manufacturer's instructions explicitly state that the bonding jumper is to be run from the bonding lug all the way back to the main panel. There are so many code references supporting strict adherence to those instructions, I assumed that they must be followed.

Peck says I'm wrong, and he may be right. What's your take on this?
