Hey everyone, long time listener, first time caller:D I'm hoping someone can help me out with this dilemma if that is, in fact, what it is.
I've been wading through the NEC, but I just can't seem to nail down the answer to this question. My wife and bought our house a year ago, and I've been slowly untangling the mess that is our electrical system. Now I'm trying to correctly ground the system.
The problem is, I have no access to the water pipe coming in to the basement. There's about four inches of exposed pipe, but that section has been completely covered by an epoxy compound to fix a leak, so there's nowhere to connect a ground wire.
Currently I have a 10' Cu grounding rod driven into the ground outside with #6 connecting to the breaker panel. I know that alone will probably not meet the max 25 ohm resistance requirement, but will adding another ground rod, 6' away, and bonding the two rods with #6 be sufficient to make an inspector happy and keep my family safe?
Or is the fact that my system is not grounded to the water pipe a very bad thing?
Thanks everyone for your help!
