I would have to say.....yes!
Picture this scenario, you are standing in a pool of water created by your leaky weldless bukhead. you flip on your pump to run your sweet wort from your MLT to your BK. All is going well, but your bulkhead keeps dripping (you've been meaning to fix that). The drips run down your rig and into your electrical socket.........zzzzzzzzzzzzzzzzt. Does someone smell burnt hair?
Sorry, but this is actually not all that unlikely. If you short your AC supply across water, it will continue to flow until your breaker kicks off (if you have one. The older the breaker, the slower it will most likely operate). A second or two is enough to kill you.
A GFCI is designed to sense this "ground fault" (Ground Fault Circuit Interuption) and open the loop so juice cannot flow. It will usually function faster than your breaker can kick off.
Did I make my point? You rig will function without GFCI, but do you want to risk it? Especially for the extra 10 bucks?
