DIY & Home Improvement

It did this exact thing over a year ago. Within half a day, it stopped dripping. That was when the plumber said it was due to water going over the edge of the tub. And once that avenue of water was blocked, we didnt see it anymore. Until today.

And it has stopped dripping completely again. Which would strongly seem to argue against it being a leak from the incoming water.

I've been playing with it a bit, to see if I can learn anything. with the aid of food coloring, I dumped blue water down tub, and red in the toilet. No sign of either color or a continuing of the leak.

This would seem to leave only two possibilities. Either my sister flailed and got water outside the tub, or water is leaking from the outside world. I dyed some rubbing alcohol green and poured it down the hole beside the tub, as I didn't want to just put more water in an already potentially mold prone space. No sign of it so far, which concerns me. I really really want it to be that, as the only other thing I can think of is a roof leak(flat roof, the other buildings have had issues, and both times this happened, it has been raining. Though the many uneventful rains in between these occurrences would seem to argue against it.
