Thus to remedy the fields from water line currents at a
house, we can simply block the metallic path to the iron water
main that provides an alternative path for part of the return
current from the house. We can insert a short length of
plastic water pipe, for instance, and thereby force the entire
neutral current to return to the power company by way of the
service cable that brings electric power to the house. There will be no
net current, because supply and return will be equal.
However, that current blockage alters the grounding, and
may have safety implications even though all electrical code
requirements are met.
Fortunately there are often other ways to reduce such
fields in a house, without actually disconnecting our grounding
from the water main - ways that alter where the net currents
flow, or how big they are. For instance, as shown in this
illustration from Chapter 29, net-current fields from the
electric supply cable can be "relocated" by changing the
cable's path. Part III (58 pages) of Silencing the Fields
covers a variety of such methods for reducing or relocating the
fields produced by these water-line currents, with their
usefulness depending on the situation.
If you would prefer to consult with an EMF professional for a plumbing current problem,

to achieve a resolution to the problem.
