Give me some examples of problems in the house caused by a poor or missing grounding electrode system.

Nope, not going to try [Linked Image]

I was trying to emphasize the _bonding_ part of grounding and bonding.

I've personally seen the results of having the phone system lightning protector 'grounded' to one electrode, and the electrical system 'grounded' to another electrode, with no bond in between....system would probably have been better off with no grounding electrodes at all.
