I have a partially finished basement in a 15 year old house. From the unfinished utility room I can see between the basement ceiling and the ground floor floor. I have the AC pipes and new copper water pipes in this space running the length of the basement. It is slighly less than a foot in height.
In the basement I hear a dripping sound or a clicking sound on a fairly constant basis. Every 30 seconds or so. This has been going on for as far as I can recall; several months. There is absolutely NO sign of water or other codensation. I figure after several months if it was a leak I would have seen something by now. The floor above is carpet on top of plywood. Could I have gremlins running around in the AC pipes? Water condensing in the AC pipes? Or is it just the floor settling?
Anything I should be concerned about?
Thanks
