What are the systems for automatically shutting off the water supply to the house?

Question

Smart House

Hello! I'm afraid the question borders on offtopic, but there were also reviews of the "Aquaguard" system on Habré. Interested in what other systems of this type exist and how they have reliability. I am writing here because Google is not very helpful (or I google wrong). And I would like to hear real feedback without being afraid of the raid of dealers of the respective companies (I am afraid of such a scenario when creating a question on a construction forum).
Do you have a system that automatically turns off the water? Which? Was there such a thing. that the flood began, but the system did not work?

Answer 1

They all have the same
water sensor on the floor and a mechanism to turn off the faucet.
the question of reliability seems to me rests on electricity and batteries

Answer 2

tell me how to control ru.aliexpress.com/item/1pcs-motorized-ball-valve-D... this using aruino uno? the valve works under voltage 12v, arduino does not give out that much, plz point in the right direction

Answer 3

I have Hydrolock. 7 years - normal flight. "Aquaguard" is actually the same, the boxes are different. It's all specialized, well-made and reliable. There is another and expensive one, but it will no longer be advisable when there is a good solution.
