Oh dear. I take it this happened during the night?...that I have to go to my son's to help fit a new toilet flush mechanism with an internal overflow.
The existing one has external overflow and when the ball-valve failed it overflowed but the pipe was just not connected to anything (previous house owner) which just ruined the room below it.
Herself wants me back here pronto to pull all the dead leaves off the huge cordyline in the front garden.
Busy, Busy, Busy.
