The red ellipse shows where I smell the gas. I smell some at lower
spots, but it's not continuous, meaning when I go lower, I don't
smell it, then I smell it, ...

I assume it has been like this during the last year, and there is no
cumulation of natural gas (like I said, only can smell it within a
foot). So I wonder, is it normal for a water heater with pilot light
to emit some natural gas odor, or should I try to seal all the pipe
joints?

How long has the water heater been there? Was it a replacement or a new
install?
