Okay I traced a GFCI problem down to a blown electric element on my water heater. Screw in type. Bought a replacemt but I cannot get the old one loose. Have a 1 1/2 socket on it but it wont budge. I am afraid I am going to damage the tank. Any ideas? Do I really need it? Can I just tape up the wires and use the propane. I am 1 1/2 weeks away from a 2 week trip in it and I dont want to cause more damage?
