Our upstairs toilet is leaking through to the ceiling below.

Resolved Question:

Our upstairs toilet is leaking through to the ceiling below. There is no evidence of water outside the toliet. We are trying to figure out where the water is coming from. We have shut off the water supply to the toilet and it appears to have stopped the leaking. We would like to know how to trouble shoot this problem. Can you help us out? Thanks, Janie

When you develop a leak such as you describe most of the time it is due to a failure of the toilet seal at the floor. Only rarely will water show on the floor around the toilet. It usually shows up as a wet spot on the ceiling below. The first thing I would do is pull the toilet and replace the seal checking the drain for any signs of defects while the toilet is off.
