Kevin, I'm afraid that's incorrect. The water itself will cause the GFI to trip by completing the circuit, it has nothing to do with the necessity of touching metal. BTW, if the tank was empty and not grounded and the heater unit was faulty nothing would happen until the horse, being grounded, touched it.
You can try it yourself by placing two bare A/C wires in a plastic or metal tank and plugging it in, the circuit will blow with the same speed wither way.
I'm not arguing with you, I'm just explaining why I'm right.
Nothing sucks more than that moment during an argument when you realize you're wrong.
It's not always what you say but what they hear.
