Identify the Rheem system you already have
Rheem offers gas storage tanks, conventional electric tanks and hybrid heat pump systems. Those categories have different installation and service needs. A model label is more useful than the appearance of the cabinet when discussing your equipment.
If the display shows an alert, describe the message exactly. If your tank has no display, explain whether the water never gets hot or becomes cold after several showers. That difference helps frame a repair conversation without assuming a particular part has failed.
Before choosing a replacement
Compare usable hot-water delivery, recovery and physical dimensions. A hybrid electric model needs a separate review of its room and condensate requirements. A gas-to-electric change also needs a utility assessment; selecting the same gallon size does not establish that the replacement will fit.
Plan service around your home.
For a Marietta home with the heater in a basement, garage or utility closet, tell the team about the location and any restricted access. Mention stairs or a narrow removal route when discussing replacement. The installation area can affect the work as well as the choice of equipment.
Compare the condition of the storage tank and its hot-water delivery before deciding on a repair. A leak from a fitting is different from a failed tank body. Learn about repair, replacement and maintenance before you call.
Describe what you can see safely. Leave gas, electrical, venting and pressure-relief work to qualified professionals.
