Be Free And Accuracy / water control device

The innovation of this device is you don’t need to worry about overflowing even though you are elsewhere and cannot keep an eye on the tap. It can turn off the tap when water reaches the specific level you have set. So you no longer have to wait such a long time in front of the pool when you need to fill out a large-capacity vessel, or when the hydraulic pressure is so low that it takes a much longer time to fill it out. Feel free to leave them alone and do what you want!
