+1Ignoring static, if you are being shocked and adding an EG helps, you did not fix anything. You hid the problem. Admittedly, sometimes that is all you can do, but not this water heater. 1.5 volts difference between water and 'ground' means little if it is a high impedance meter.
Why not replace the heating elements to see if that cures the issue? All that $$ to run new wire w/ egc?? I would have used that $$ to replace the element(s) 1st.
And what new wire? Is this a 3 or 4 wire thing? If it were a 3 wire previously w/o egc then the N would appear to be lifted somewhere or not ties to egc at some other location. Or, was it just a crapola 2wire previously?
