Hi Scott, 


A much better idea is to invest some time resolving the RFI... 


If you you have an EE degree or you're a licensed electrician 
you understand both RFI and the consequences of ground faults 
already. 


The green wire to your water heater provides the only direct path 
back to the circuit breaker, copper plumbing provides an indirect 
and less reliable path back to the circuit breaker. 


The green conductor path will trip the circuit breaker if a live wire 
in the water heater shorts to a grounded conductor for any reason. 
The copper plumbing path might trip the breaker or it might not. 


Maybe you no longer take cold showers, but the intentional 
removal a NEC required green wire circuit could prove to be 
a whole lot more inconvenient than that...
