Stuff a paper towel into the opening around the filler neck.
And stuff one from down under up into the exhaust opening.
What we are trying to do is identify the leak before we conclude it is the most expensive one. The most expensive one occurs at the welded penetration where the Aquahot exhaust penetrates the drum that contains the coolant. That one requires the tank to be replaced. My experience is if the tank is leaking there, that the area around that penetration is rusted through, and patching one leak only results in another. It may be possible to fix that by welding a large scab patch over the area, but that also involves removal of the outer copper coil that handles potable hot water.
