I have seen houses where the water mains was used as the source of obtaining a "good earth" to ground everything else within the house, including the fuse box and the "green wire".
Another time I was told that water pipes are earthed to avoid a harmful potential to occur on any on the water taps.
Now I see a house which has a rubber hose coming from the well and pressure tank, and copper pipes only start to be used after the softener tank. Still, the fuse box and the telephone cable are religiously connected to one of those copper pipes.
Who is earthing whom? A water filled rubber hose can't be a "good earth".....?
