Dripping sound from pipe
I have this dripping sound coming from the piping underneath my bathroom sink. It occurs regularly, approximately every 30 seconds, regardless of how recently the water was used. But it only seems to occur during cold weather outside (e.g. Below freezing).
I even tried turning the water supply off and draining all the pipes and the sound still occurs. Could this suggest something other than a leak? There is no evidence of water damage and this has been going on for a few months.
Here is a video link with the sound : https://m.youtube.com/watch?feature=...&v=PtpaTJieh84
Thanks

Welcome to the forums.
Video is good for visual reference but I didn't hear anything.
Is there anything above that room ? Bathroom ?

There is a drip sound in that video, towards the end. All I can tell is that it is coming from the opened up area in the wall. This is on the second floor of the house. I can also hear this same sound coming from the wall from each floor directly beneath (the first floor and the basement). However, it is loudest on the top floor.

Do you have a heating furnace in the attic ?
If not..... is there anything above that room or is it attic and then roof.

You state it only occurs in cold so there is probably a vent stack close by and warm moist air is condensing and dripping inside the pipe.

Since there is nothing above that.... the pipe I see going up the wall is the vent line. It would have to be condensation as there is nothing else left to leak and cause water to drip.
