1995 Fleetwood Tioga Montara - hot water tank leak

De-winterized the RV (Ford chassis) yesterday.
Put the buttom plastic drain plug in, switched from bypass to normal.

Filled the tank, at the end started gushing out of the top connection.

First thought: freeze up. But then: that would not occur on top of the tank

I will get the make and model of the heater a bit later.

First searching for DIY instructions, came across one video showing an Anode Rod for corrosion protection, and the recommendation to change that often. Have not been aware of it, never changed. Is this the likely cause (anode corrosion rod worn, no tank corroded, creating the leak)?
  • Is the Atwood 96121 the compatible replacement? It seems they have switched their model name system.
    The 96121 I found also as Atwood G6A-8E (vs 7E of the current) and G6A8E DSI.
  • The model is G6A-7E.
    Looks like (electric ignition, not the pilot light version) its a 6 gal, around $400 to replace.
    No sense even checking WHAT created the leak and if fixable?
  • 1995? If original, time for a new one. I read somewhere that water heaters (propane/electric) have an average life-span of 15 year. Might be true.
