Comment on Upgrading ungrounded two-prong outlets to grounded three-prong?
sj_zero 3 days agoIn many jurisdictions, connecting to the copper cold water line is acceptable. The copper line runs through the ground and so is essentially the same as a grounding electrode.

Until someone does a repair using a non-conductive replacement part. If your ground is running through your sink, and your sink springs a leak, there’s a non-zero chance that the new install will be PEX instead of copper. Still up to code from a plumbing standpoint, but now people in the upstairs shower are getting shocked because the upstairs outlets are tied into ungrounded plumbing.

Ideally the ground should be as close to the cold water pipe entering the house as you can get, yeah.
Honestly, I wouldn't want to just use my cold water line well into the house as a ground for exactly that sort of reason.
