I have a customer with an existing hydromassage tub. The pump and motor are located outdoors, next to the bathroom wall. It is a GFCI protected, dedicated circuit. The piping is plastic. A home inspector says the pump motor needs to be bonded. There is no other metal in the motor area except for the GFCI enclosure. Does this installation need to be bonded? And to what? The main panel? The motor is already grounded via the circuit grounding conductor. My code book is at home, where I'll be in an hour. Meanwhile I would appreciate any input. Thanks, Brian

If all the piping (water supply included) is plastic sounds like there is no piping to bond. I would bond the gfci enclosure to the motor. The motor is bonded to the panel through the egc.

Thanks Scott, thats just what I'll do.
