got a call out to attend a flooded bathroom well here is the reason why: - the soil pipe and its boss shown here:

After donning my drysuit and snorkel, i waded in and had a fight with the boxing that was bodged in place that had also swollen so much it was wedged in place.
Turned out that this pipe also served the basin and bath, however the bath trap is 2 inches lower than the boss in the soil stack.
hence why it pulled out - the weight of the water has obviously pulled the pipe out of the rubber boss and it snapped the plastic bath waste, so when plug was pulled water went everywhere but down the drain.
I informed the new homeowner of this, and they are gonna get the insurance to pay for my remedial works and for me to fit a new bathroom.
Now this was a house converted into a flat by the previous owner, and guess what this was a general room. but were building control informed as per the regs - No. shame as this could have been prevented.
