: Any suggestions on how to discover what is leaking?
: Have a bathroom beneath a shower & an adjacent toilet which are upstairs. Ceiling over the downstairs toilet is leaking. Thought it was the tile, had that sealed. Thought is was a pan leaking in shower & had that checked and found out no pan because it is a prefab unit. Thought it was the toilet, had it replaced. Fixed the ceiling below and thought that took care of all--started getting water stains again.
: Is it possible to put a colored dye (that wont harm a new expensive toilet) in the toilet and wait to see if that color appears on the ceiling below and if not put a different color in the shower to see if the prefab unit is leaking. Or is there any way to detect the leak short of rebuiling the 2 rooms!!! Appreciate any answers,

That sounds like a good idea, the different colored dye in the water. The toilet wouldn't be a problem, but the grout in the shower may be worrisome.
One method I use, is to plug off the shower drain and fill with a bucket.
If nothing there, you can try plugging off the shower head and turning the faucet on.
Depending on the age of the home, it could be pipes. One time I found a cracked ABS fitting that was leaking and the only solution was to cut it out and replace it. Happy hunting. Terry
