Most people assume water leaks in the home come from faulty plumbing, but my experience is different. There was an inline water filter underneath a Kitchenaid Superba refrigerator that was sitting like a time bomb, waiting to leak. Unless you unscrewed the bottom access panel, you'd never know it even existed. Then one day, over the course of 24-36 hrs, it springs a large leak. Many gallons of water soaked into the hardwood and caused it to warp. Well that's history, and you live and you learn.
To prevent future disasters, I got rid of the filter system entirely, and just shut off the water to the fridge. Who needs ice water when it can cost you $10,000 to repair floor damage? Now, I'm paranoid about the other appliances that have a water line connection, including the dishwasher and hot water heater. What is the best leak detector with a shut off relay that can cut the flow of water in case moisture is sensed on the floor? Is the prevention worse than the disease?
