I know the warranty on those heaters are very good. Since the heater is a rental I am going to try and get ahold of the rental company, American Water Heater Rentals, however this may cause them to tell me they need to reposses it for non-payment by the previous owner of the home who passed away.
If I cannot get this replaced under warranty I was checking to see if there are any ways to get the heater fixed. Seems to be the brass fitting for the element has lost its seal with the inside of the tank.
I think I am going to go with the standard metal water heater if I have to get a new heater.
