And what is your concern?Originally posted by problemsolver600:
I had to move an exisiting service in a Cook Co. community, and was required to upgrade the ground to 4 guage, install the bonding jumper at the water meter, install a grounding rod ouside, and GROUND THE HOT WATER, COLD WATER, AND GAS PIPE AT THE WATER HEATER, PER CODE.
I still have the inspector's notes in my files.
