Adopting the invention, when all the water valves are closed, the control switch is turned off, so the water pump control box stops power supply to the water pump, and the water pump does not work; when any water valve is opened, the control switch transmits the switch signal to the water pump control box, so the water pump control box supplies power to the water pump, and the water pump works normally. Using the water valve to control the operation of the water pump cna reach the effect like the tap water in the city, which has the advantages of simple structure, convenient construction, safety, low cost, low energy consumption, which can completely replace the water tank, and the water route and the circuit are separated, while the pipeline can be sealed with the well mouth with safe and healthy water utilization.
