Just saw a thread on some posters who's taken off his wall paper to find foil lined walls and got to thinking of the horrors i discovered when i bought my secondhand property and inherited the previous owners DIY disasters. I wouldn't blame him for the crooked walls (old house) but i do for the sink that had both hot and cold taps connected to the cold pipe. the shower connected to the mains that was only usable very early in the morning when nobody else on the street was running water. the toilet waste outlet that met up with a downpipe from the gutter and all went into the sewage etc. i actually had a survey done on the property but none of these were noticed. My cousins new build actually had a toilet that flushed hot water because connected to the wrong pipe. All has had to be fixed but interested to know am i the only naive person who's suffered at the hands of someone elses bodge-it-jobs? Whats the worst?
