Thread: Copper Water Pipe AC Currents/Electrolysis

( Agree'd. , )

Yes stray currents imposed on copper piping can lead to blue-green water/odors/taste issues.

Because of building wiring errors,30-40 amps of AC neutral/ground current was flowing on these water pipes in a large commercial building(water source is wells and is very hard). Is it possible for a copper chemical electrolysis reaction to occur and create large constant green deposits to be discharged from this water system?  

( Definitely. Some think that you need DC for that to happen. And DC is more "efficient" than AC. But, if water moves, the copper ions that leave metal during positive halfwave and are supposed to return during negative halfwave will be spooled away and never find their way back to the metal surface they left. That makes AC and moving fluid just as bad as DC with respect to electrolyis. , )
