I have a dripping noise coming from the upstairs bathroom, that I hear in the ceiling of the room below. It drips all the time. Sometimes fast, sometimes slower(3 seconds/per drip). There is water on and around the ceiling.

It can not be hot/cold water pipe leakage. Otherwise, I could hear the different noise of “sh…sh…” and a lot of water would leak out.

It can not be drainage pipe of upstairs bathroom. Otherwise, the noise should stop when faucets are shut down and water in drainage pipes ran out.

I guess it is because of condensation on the cold water pipe above the downstairs ceiling. But how could I make sure of this guess?

Any ideas as to what might be causing the problem, or how I can avoid tearing up downstairs room’s ceiling? Thanks a lot.

Zjclucky - Don't give up on the fact that it can't be the camode . Ill tell you what , take some red food coloring and pore some in the camode tank let it set fror about 30 min. to an hour ( Don't LET ANY ONE USE DURNING THIS TIME) Now check to see if the water in the camode base has red colored water in it , If it does then replace the flapper in the bottom of the tank, I have found this to happen once in awhile , If this don't help come back on and we'll try another route . Good Luck & GOD BLESS ::: F.B.E.

Thank you very much.

I checked the toilet's drainage pipe under the toilet. It's dry. Also the position of toilet is away from the noise of dripping. So I think it must be something else.
