Refill the tank partially so the tank doesn't move when trying to twist the element. 3. If all fails, use hammer to remove terminals and plastic end of element > on the newly exposed surface of the element, drill and tap two 1/4" holes into element > keep holes close to center of element so not to damage the element threads > twist two long 1/4" bolts into holes > use a wrench or vice grips to grab the two bolts and twist to remove element. 4. If you are having trouble removing the element, try repeatedly tapping on the element with a small hammer to break the corrosion loose.
