The Grounding Electrode

Plastic piping is not only widely used in new installations, but also in repairing existing installations. Even in a metal water piping system, maintenance and repairs can introduce plastic pipe fittings that interrupt the electrical continuity of the system. These fittings can also significantly reduce the length of piping that can act effectively as a grounding electrode. Water utilities do not commonly install jumper wires around the fittings to maintain electrical continuity. In fact, many utilities discourage the connection of buried parts of metal water piping systems to the electrical system. They say that electric current through the pipe can hasten corrosion and affect the taste of the water.
