Mysterious leak dilemma.
In the basement, occasionally (weeks apart), one or two drops fall off the plastic drain elbow directly under the toilet upstairs. Apparently there's no leak coming from inside the pipes. Nor is there water seeping under the toilet (floor is dry). The leak doesn't correlate with usage. Repeated flushings do not show any leaks. Ditto for other fixtures.
Could condensation be responsible? Vent stack leak? Any other ideas?
TIA!
That was going to me my guess.

Maybe just variations in the humidity of the basement. On high humidity =
days, it may condense on the trap? Whenever you are in the basement, feel the trap for wetness. Just after I moved into my new house, I noticed a string of wet spots on =
the basement floor. It turned out to be condensation dripping from one=20 my cold water pipes (55=BA F well water) running along one of my joists. = I=20 subsequently covered all the pipes with foam sleeves.
Try a dye tracer in the toilet to cofirm or acquit that as the source. Reducing basement humidity via open windows, whatever, may eliminate the problem. HTH
