I hope I am posting this under the correct forum. I have not been to the job and it's too far for a call however I am curious anyway. Here is what the woman has described. All her copper cold water pipes are turning black. She also says the a/c refrigerant lines (liquid line) is turning black as well. This isn't the isolated spot where you have copper touching a duct or something. It's the whole line and may even be inside as well.
I asked her and she says she has well water with plastic pipe coming in. Obviously her only ground for the service is to a driven ground. She claims it feels very loose in the ground and has a couple feet not driven in. 4 yr. old house! She has done some checking on line and seems to think it may be grounding herself.
I've never seen this before but most of my area has copper water service from underground so the panel is grounded to that and not solely depending on a ground rod.
Can a circumstance with poor ground cause this problem? I would think it should make the hot lines turn black as well though. Even with dielectrics at the water heater, at some point in the house the hot and cold have to touch or show 'continuity' if you will.
Thanks all (hopefully)
