Re: Electrolysis
Tell them to explain it
since they Understand the grounding requirements stipulated in Article 250. You could also reference Article Exibit 250.27 for reference. And Part III, read Article 250.52(A)(1)Metal Underground Water Pipe. You are headed in the right direction. Are they licensed electricians?
Off the record I don't see how two alloys that have identical properties and are properly bonded together can produce the eletrolysis that the guys are speaking of. :roll:

Re: Electrolysis
It does not. I have a copy of the definitive report by the american water works association "Effects of Electrical Grounding on Pipe Integrity and Shock Hazard" they built a test house in Orlando and tested many combinations of voltage and current, conclusion, no electrolysis.
However, water with a low pH (7 and under) is considered aggressive and will corrode the lead and copper from fittings and attack the natural copper oxide (blue film in pipe). The solution is to raise the pH to about 8. My municipal water is treated with sodium hydroxide (er Draino) to raise the pH.
Ask your plumber what the pH is, and if your water supplier has complied with the EPA lead and copper rule.
I also have a copy of an IAEI report done in 1944 that addresses the same question, the answer from 60 years ago, no.
