My main grounding wires from the breaker box has 2, one side of the panel goes outside to a grounding rod. The other side is a thick cable that runs about 60 feet to the in coming water line. But the water is copper but the line it connects to going through the wall is plastic is the really grounding anything? A friend said the water in the line is giving it a ground. So is it ok like this or should if have been done another way? The house is 2 years old.
Thanks
