plumbers cutting into copper lines and installing pex

[LarryFine]

in my house the only grounding electrode i have is the water pipe. no ground rods or anything.

In a building I wired last year (business downstairs, two apartments up), the only electrode is the pair of rods; original one and one I added.

So when you saw all this damage to ?romex? was the purpose of your call due to the metal water pipes being energized?
It couldn?t have been due to the breaker tripping or fuse blowing if the pipe wasn?t bonded in the first place.

Did this same basement have metal duck work installed? Was this metal duck work also bonded before you left?

Did I say I actually saw damaged romex? Nope. I did not. Only the greatly increased potential for it to happen. I think the bus just drifted into the ditch and rolled over. Like Gilda used to say - Neeeebermind! :grin:
