Had an idea for a safety device

Maybe there is such thing, but wonder how it differentiates a broken pipe, or someone filling the bathtub. Guess it's time based too, like if it's been going for an like half an hour then something is wrong.

Ideally you'd have a neural network that learns your weekly water usage patterns and trips on anomalies. For guests and special events you could have a manual override.
False trips are probably not harmful unless you have something that is 'harmed by the absence of water' so this could be programmed with a slight bias in the 'safe, not sorry' direction.

Hmm yeah that makes sense. Most appliances such as dishwashers will detect lack of water and stop operating right? A washing machine for example will wait till the water reaches a certain level before moving on to the next cycle, so worse case scenario it just stops until the water is back.

If you can write good BS in a proposal, someone will come up with venture capital for this project and then I can start hiring illegals to assemble these things.
