customer has experienced slight shock at times in the shower
checked between drain and shower head- around 8-10 volts
not phantom, does not change when checked with a solenoid tester
turned off main, voltage goes away
as the 2 pole radiant and baseboard heat circuits are turned on, there are 4 circuits that translate into around 2-3 volts at the shower when each are turned on
when all the heat circuits are on, it adds up to around 8-10 volts
no other circuits in the house have any effect on the shower
should I open the wall and just bond the drain to the showerhead?
