Discovered a high pitched "beeping" sound (2 times per sec) coming from behind the wall near my ensuite toilet. It comes and goes, but not audible from the rooms on the other sides of that wall...house is about 16 years old.
There's no electronics or wiring in that area, only plumbing...and to my knowledge I haven't pissed off Mossad or any Iranians.
Any ideas?
