TIA I'm helping a friend from a distance. Second floor bathroom: when the toilet is flushed water is leaking into the room below it. My guess is the waste pipe connected to the toilet might have rotted through? The toilet is secure and no water is leaking onto the bathroom floor, and the water level in the toilet is not going down, it remains at the normal height once the tank refills. I'm going to make a trip there tomorrow and have a look, maybe remove the toilet and get the scope down there. Any suggestions would be appreciated.
