Electrical shock from shower handle.

[aftershock]

I had this same problem with a customer a few years back.

The upstairs shower/bath was getting voltage through the metal drain/faucet.
I tracked down the voltage to the stove circuit. (Turning off breakers until the voltage ceased). We cut loose the old stove circuit and ran a new one.
Problem solved.

My first thought would be to check all grounded conductor connections and have POCO check theirs.

If they have a submersible well pump this could be a culprit. Had this happen to a customer once with the same symptoms. The shock they were getting was intermittent, I discovered it was when the pressure switch called for water. When the well pump company pulled the pump one conductor had nick in it. It took most of the day to figure that one out. $$
Good luck.

Had same problem before as you describe. It was a open grounded conductor between utility side of meter and their transformer. Before calling utility a checked and found a voltage inbalance at the main service panel. L1 to ground was 80 volts and L2 to ground was 160 volts. These numbers vary depending on the load.
