According to the NEC a buried pipe with corrosion protection over 8ft long is an acceptable grounding electrode, with a listed hierarchy of preference for different types of pipes. Metallic water pipes are 1st on the list. Normally other pipes are used only when the water pipe is non-metallic.

I know, I know... its a Dead issue BUT... (no Pun) I really hate to bring it up again... But hear me out: My A/C service entrance does not have a ground rod. My house was built about 25 years ago.' I pulled the service front panel and found the following: All the grounds and neutrals are bonded to the metal chassis as they are supposed to be. But there is no wire for a connection to a ground ROD! It looks like they used a solid metal pipe that houses the big A/C wire inside of this pipe. This pipe IS connected to the service entrance by some metal gland nuts. The 2 1/2" pipe goes outside of the house and is buried underground. It goes off to a transformer that is about 100 yards away. So my question: IS this pipe MY Ground rod?
