Water Running behind walls

I hear a water running sound behind my some of the walls. There is visible leak or wet dry wall etc. I checked every single faucets, 3 toilets, turned off reverse osmosis, turned off ice makers, turned off cold line to water heater, still the sound is there. strangely the water meter is not spinning either. But when I turned off main shut off value the sounds stops.

So I called my home warranty folks. he is really puzzled with what is going on. please let me know if anyone has experience

Some houses have hot water recirculation so that you don't have to wait so long for it to reach the tap.

If there is a visible leak, then that is where the water is coming from. What part of the US are you located in?

Is that a typo "There is visible leak or wet drywall ect."
Not sure if that means there is, or is not visable damage.
Single family home?
Added red food coloring to the tanks on the toilet to see if it leaks into the bowl? (leaking flapper)
Forced hot water or steam heat?
Under floor heating?

If there is visible water damage I'd open up the wall to inspect, the odds are that portion of the wall would need to be accessed to fix the leak ...... if the wall is wet.

That's a typo guys. There's no visible water damage and the meter doesn't spin with everything turned off.
Strange indeed, a recirculating pump like X said is a good guess. Any leaks would be seen on the meter dial.

Thanks a lot for all the replies, Sorry about the Typo. Yeah there is no visible leak or dry wall . I'm in southern California. called two plumbers and they couldn't identify the issue. My biggest worry is why I hear this all of a sudden. I have been living in this house almost 4 years.
