Arrived on site and customer stated water was coming out from underneath the water heater in the garage . I found that the heater was leaking from the unit and into the pan , as it had rusted out . I provided the customer with a few options to choose from which included a 4 year extended warranty kit and an ionizer. I then proceeded with the install . After heater was installed , we checked all connections and filled the heater . Once filled we turned the unit on and check for the flame and set the temperature to 120.
