Agree. That is a huge amount of water. From the first stories, it just looked like it was along the joints of the ceiling and had probably come out of the light fittings but it's obviously been a lot more and there is more trapped. I think the plug has been left in too. Bathroom floor will need to come up as well.The ceiling needs ripping down. Its fucked. If there was that much water to have caused that much damage the bathroom floor will also need ripping out. That’s not someone leaving a tap running accidentally either. A tap left on at full force and deliberately blocking the overflow/leaving the plug in…..
What are the things that look like rats' tails on the washing line?!
