A newly renovated home will have a service upgrade from 100 to 200 amp.
The home is built on a slab and the water main entrance is under the kitchen sink 2 rooms away.In addition to the installation of a ground rod, the #6 Al GEC to the water main will need to be upgraded to #4 Cu. In order to not disturb the newly finished interior of the 2 middle rooms, I am considering attaching the new GEC to the water main underground,immediately outside the home.(There is more than 10' of pipe). Any thoughts?
