(Mad Inventions)burst pipes

I would like to see an invention where if you have a burst pipe in the house then the water will switch of automatically.I have had really bad personal experience a few times where you start to panic because you cannot find the way to switch of the water.The thought of the ceiling collapsing amd a massive flow of water in the house is very scary. The mess this makes is a big pain in the neck to say the least.
