Just had the water heater corroded union fixed, and now noticed the bottom
is leaking. I don't think it's related however. The water is leaking about
one drop every 30 seconds or so, very slow. It is a tall boy Bradford White
HydroJet and it's sitting on a concrete pad. I tried to see but there is no
way to tell where it is leaking unless I turn the heater sideways which I
can't. Does this mean this heater is done? should I even attempt a repair?
