Review on Camco Residential Screw Heater Element Rough Plumbing by Emanuel Guffey

The shaft itself (with two holes on one end) was too short for my wheeled water heater and consequently the key didn't protrude far enough out of the heater compartment to slide the pole through. like a shaft on a screwdriver. This is important as you need to be able to apply enough force on the rod going through the key shaft to dislodge the water heater electroblock and in my case the side panel of my RV got in the way. An inch longer on the shank of the wrench would have done the trick. Also, the "end" of the wrench was slightly oversized so it didn't fit properly, that is, until I hammered each side of the hex. little. The job didn't take 15 minutes, but about an hour.
