If anyone knows about cathodic protection it's a Navy man. The only place I've seen it used is to protect the water heater of one manufacturer and they use a replaceable sacrificial anode screwed into the tank. The other popular manufacturer does not, I think they use a stainless steel tank but I'm not sure. I also don't remember which company uses the anode. Hope that helps some.
