Look carefully to see if there is a little dribble coming out the TP
valve (Temperature & Pressure on the side near the top of the tank with as
pipe going down almost to the floor. You might even try touching it to see
if you can feel the sound. I could be building up too much pressure in the
tank due to no pressure release and too much pressure in your home.
It also could be build up of deposits on the bottom of the tank. As
noted in some areas 7 years is a good life for a tank. It depends on the
local water conditions.
The pressure issue can and should be addressed. A weak TP valve is easy
and cheap to replace. Not much you can do after the fact about the build
up. That usually means it is time for a new heater as would any actual
leak.
