Bought my house from a younger couple who were DIYing. There's multiple things that have gone terribly wrong. They did a terrible job. But this is the only plumbing story I have is from about April of last year when my girlfriend was 8 months pregnant. I went to a little last minute golf trip with my friends who were helping me celebrate a last hoorah kind of deal. We get smoked, of course. 10pm rolls around and I get a frantic phone call from the GF who is bawling her eyes out. She was taking a bath in the guest bathroom which happens to be over the garage and heard a big crash while she was in the tub. She goes out to the garage to find a giant hole in the ceiling and water everywhere. Now she'd been taking a lot of baths because pregnant and apparently a ton of water had been building up and the drywall finally gave in. Giant hole in the ceiling, wet drywall/plaster fucking everywhere, had to hire a plumber to come out and fix everything. It was a fuckin disaster.
