Hi,
I have a top-floor condo and recently found out that the bathtub in our
guest bathroom is leaking onto the ceiling of our downstairs
neighbor's bathroom immediately below it (very noticeable drip).
I tried isolating the cause of the drip and found that it only happened
when water runs down the drain.
This may be a silly question, but does anyone have any suggestions on
what I could try from within my unit, without having to open the
ceiling in my neighbors unit?
It seems to be a plunger style drain if that helps.
I'm pretty sure the condo complex's master policy would cover the work,
but at the same time I love doing projects around the house and hope to
have a go at it first.

Likely the trap is leaking. Best looked at from the ceiling of the unit
below you. If you think the leak is directly above where the stain is, you
could just cut out a square foot of sheetrock around the dripping place, and
see where the water is coming from. At that point you can decide if you wish
to bring in the condo repair guy. Your condo agreement may also limit the
work you can do.
