Water heater failed due to expansion tank not being supported and something to do with the wiring. I strapped the tank and inspected the wiring. I noticed the hot wire had a little bit of wire showing under the wire nut. I trimmed wire down so the wire nut was completely covering wire. There was no inspection report left and tenant was told she could look it up online. I had no access to the report and fixed what I saw wrong to the best of my knowledge. No charge for warranty issue.
