"If this were my own property, I would want the UFER or a ground ring, regardless of what the code requires."
Me too... Concrete pad, and /or footings bonded to the motor control box in the very least.
Been on too many service calls where people get shocked by touching the water, and standing on the ground barefoot.
GFI's and pump motors fail, heaters burn up over time, landscrapers pick ax the feed. Who knows what else... But at some point something will go wrong, and someone will be standing there half, or fully naked for what ever it is....
