Why does my ceiling leak when I flush the toilet?
Toilet – The seal between your toilet and floor is called a wax ring. A faulty or worn-down wax ring can allow water to leak into your subfloor and ceiling each time a toilet is flushed. Bad wax ring symptoms include water on the floor near the base of the toilet and an unpleasant odor of sewer gas.

Why do I hear a dripping sound when I flush the toilet?
We have two washrooms on third floor and it’s only one of the toilet that’s causing this. No sound when the other toilet (on the same floor) is flushed. No sound when using shower or sink. But when this toilet is flushed I can hear water dripping sound even when I’m on the first floor.
