New tank replaced early-mid January this year.
Just noticed this on the cold water inlet side of the tank. Notice it's only on the area closest towards the flue.
Is it just to incoming *cold*, temperature difference and just the heat from the flue ?
When I look at the hot, it looks clean.
trained eyes who are in the know, what is this is see on the cold inlet side.
