Water Pipes and Electricity.

Water Pipes and Electricity.

In a recent issue, says The Metal Worker, we noted a report that came from England respecting the destruction of lead water pipes that were near the underground wires of an electric supply company. We mentioned it as an unanticipated danger to the durability of lead pipe, but we did not think it was likely to prove very frequent. Already, however, other instances of the same thing have come to notice—one case in the city of Saginaw, Mich., where a lead pipe ran for some distance parallel to the electric railway. Investigation proved that the pipe had been very seriously corroded, and when taken up it was found to be pitted like an old storage battery plate. The other case is reported from the city of Athens, Greece, where a lead pipe was used for grounding an electric wire. In this case the electrical action resulted in the formation of a series of small pin holes, though a curious thing was that where the water pipe was in contact with flowing water the lead was uninjured, but if in a damp place the corrosion was very serious. Soldered joints also were very seriously attacked. Those investigating the matter were all of the opinion that the corrosion was due to the electrical action. If the danger threatens to be a serious one, however, the electrical companies will probably be required to provide against the destruction of neighboring water conduits.
