all of a sudden near my water heater in the garage
something is making a dripping like noise
it sounds like it's the water heater,
but no water is seen anywhere
the washing machine is on the other side of the wall,
and a little less noise can be heard there
no water leaks to be seen
what might this be?
[about 2 drips a second]

Does drain plumbing come down inside the wall? Washer is
there, so some plubming is in the area. Any chance a
condensate drain for an AC, like in the attic, is routed
down through that wall, maybe to a basement sump pit?
If the WH had a leak, 2 drops a min, it wouldn't be long
before water showed up on the floor.
Gas or Electric? If it's gas, try using a flashlight and looking down the
flue hole when it is heating water. You might see mist, indicating a leak
in the flue.
A few years ago I began to notice occasional water on top of the water
heater. Sometimes it would be there, sometimes not. I checked all of the
pipes and fittings and they were always dry, even when there was water on
top of the tank. It turned out that just below the top of the tank, a hole
had rusting through the flue and mist would blow out whenever the tank was
heating water. They mist would rise with the flue gases, make contact with
the "inverted funnel" at the base of the external flue and drip back down
onto the top of the water heater. If not noticed soon afterwards, it would
Perhaps your flue is leaking someplace where you can't see it, and the
condensation is dripping someplace, again, where you can't see it.

Only thing I see there that's a bit unusual are the water stains
on the sheetrock near the bottom. Is that from something you
know about from the past?
Any evidence it's wet now, ie that something is leaking inside the wall?
The area around the bottom of the WH is all dry and it has a pan.

That's a good catch. I assume you still need one, even if it's hooked
up with flex pipe, since the purpose, ie to catch any small debris that
might come along before it goes into the valve, would be the same. The
fact that it's missing would be another indication that whoever put it
in didn't know what they were doing and it probably wasn't inspected either.

If the pipe is copper it probably is from the TPR. If the pipe is dry then the TPR is probably not at fault or there would be water inside the room or the drip pan.
I suspect the laundry area.
There is no way I would open an exterior wall except as a last resort. I can patch interior much more easily.
a neighbor told about a leak in this house,
above the water heater, in the wall;
so I cut a few holes up there,
and sure enough, there was the leak
[I thought I would have to move the water heater,
to get at the inside of the wall;
that's why the stucco seemed simpler]
Now it's just a leaking copper to PVC joint to fix
That's good. But remember there is tool you can use to pin point
a spot where water is leaking. Plumbing outfits have it. It is
very sensitive high power microphone so to speak of. It can detect
leaks right on.
for those interested

thank goodness for my neighbor,
pointing out the location;
i would have started at the bottom,
and would have removed the water heater,
or worse, cut into the lower stucco, outside

Thanks for the update, glad you found it so easy. And I agree, you
got very lucky with the neighbor.
IDK what we're even looking at there. Never seen anything like it.
They transitioned from copper to cpvc, but what kind of connection is
that? It looks like it's a crimp? And what's that greatly reduced size
elbow doing there?
Good grief. You have to wonder what else they screwed that you don't
