Dripping sound from water heater?

[Fulltimers]

We just moved into our 2015 Aerolite 319BHSS. We heard a slight sound that sounded like dripping. We took off grate behind toilet and isolated the sound to the water heater. There is no water on the ground or any other sign of this being a leak except for the sound. It's an intermittent clicking sound and continued even with water off.
Any ideas on what this might be? Thank you!

Can you see the lines behind the tank. We had a leak for quite some time, one of the crimped fittings was not crimped. No damage, just dripped into the belly and accumulated water, though it to a couple of months to find. Now that it is crimped, I check once a month, but have not seen it leaking, nor have had water accumulating.

Also, I would imagine that the leaking is after the hot water heater on a hot water line. If you still hear it with the water off, the pressure built up from the heated water would lead me to believe that a fitting close to the heater is leaking. You could turn the water off AND drain the HW heater....ensure you turn off the heating elements (gas and electric - if equipped)!!!!!
