Let me tell you a tale...
A few years ago my parents were living in a house with one of those movable dish-washing units. It had a "counter top" on it that matched all the other counters and could be rolled around to anywhere in the kitchen. You'd then plug in the power at the nearest plug and extend a hose connection to the faucet. System worked just fine for 7 years.
Well, one night my parents started a dish load just before they went to sleep. This was not uncommon for them to do. Also, the little spray nozzle next to the faucet that was used to connect the dish washer had been replaced (the handle broke off the previous one). At some point in the night, the new spray nozzle blew off due to water pressure, I guess. Anyways, water shot straight up in what had to be a very mighty jet, as it punched a hole in the drywall ceiling about 1/2" in diameter. Water was steadily shooting up into the ceiling for an undetermined amount of time.
Evenutally, my Dad, who slept in the basement, heard what sounded like heavy rain. It sounded odd to him though, so he got up to see what was going on. Water had been shooting into the kitchen ceiling and traveling down through the walls of the house, and was now POURING into the basement at a fantastic rate. When all was said and done, the house needed:
- New kitchen ceiling and floors
- New drywall everywhere
- New basement drop-ceiling
- New basement carpet
- 2 weeks of very aggresive dehumidifying
Bonus: My parents were renting the house and were already set to move out before any of this happened. I'm sure the owner thinks they did it on purpose.
TADA!
