Sounds like the tank has a pinhole in it. Time to replace. I'd get a Dometic should be basically drop in.
Dometic IS Atwood.....Acquired them last year
Atwood Part Numbers
OP....can you ID exactly where it is leaking?
Tank is aluminum---it can be welded to fix a leak
Wrap top and bottom water fittings with Toilet Paper and see if either gets wet.
Place some TP around bottom area ...check for wetness
Place some under drain plug in outside compartment and check for wetness
GC10A.......combo gas/electric so remove cover on backside of WH Tank where electric element is installed and use TP to check for wetness
TP will show a leak very quickly
What is rest of model number?
GC10A-XX
GC10A-1E, GC10-2E & GC10A-3E all use same replacement tank
Atwood 93953 ($265 if you shop around)
