I had posted the other day that we had some large magnetic fields due to current in our water pipe.
Well, the utility and the electrical inspector found a lose connection at the transformer.
The EMF leves in our level room can down from 15 milligauss to ~ 2 milligaus....which is great.
We had 2 to 4.5 amps of current in our water pipes, which was created the large field. The current is now down to ~0.3 amps, still creating a small field.
However, I'm not going to stop there. I'm going to put in a dielectric coupling in the copper pipe so that the current is ZERO. Plus, the next time there is a loose connection with mine or my neighbors neutral, we won't get current in our pipes.
