Is It True That Electrolysis Can Cause My Copper Tube To Fail?
Electrolysis is an overused and misused term when applied to copper tube. True elec-trolysis, or electrolytic corrosion, as it is more properly designated with regard to piping, is caused by an imposed (external) stray DC current and virtually ceased to occur with the disappearance of the trolley-car that was powered by high amperage DC current.
