water pipe as ground how much is needed
I got a bad leak on my 60+ year old pipe in from the meter
so want to replace the steel 3/4 inch now down to less then 1/2 line with a 1'' PVC line
how much steel line in the dirt makes a good ground of the electric service ?
I plan on leaving about 18 ft of steel as it is under a concrete slab
but not having a direct connection to the main water pipes as the PVC is not a conductor
do I need to run a wire to ground to the supply pipe or is the existing 18 ft sufficient
for grounding my house ?
