Bent Pipes

Woke this morning to find water on the dining room floor coming from the ceiling. Took up the bathroom floor ( Yes - it's definitely Xmas!) and couldn't find any leaks - just lots of condensation on the toilet cistern! Put all the floor down ( after taking a picture) and we'll see what happens tomorrow.  Modern plumbing is so different - all plastic! Where's the copper and solder gone? I've put the image through a filter to show how I now see the pipes!
