house and grounding

Hi,
I just bought my first house - it was built in 1950, and although the panel has been updated, there is no grounding rod. I do know that it is grounded to the cold water.

Do you suggest that I have a grounding rod installed as well, or am I OK with just the cold water ground?

Any advice is greatly appreciated.

Sincerely,
David

The cold water electrode is probably sufficient. It may be the only method required in your jurisdiction. Perhaps if you were bringing an electrician onsite for some other work you could ask about it, but I wouldn't recommend a service call just for that.

I agree with Ben. A ground rod is supplemental ground. The water pipe ground is your primary ground.
