Applied for a patent in Turkey, planning to apply in other countries. The invention relates to an electronic unit that automatically controls the pump by being attached to the water pump without a balance tank and pressure switch in order to reach the user in places where water use is required in cases where water pressure is insufficient. In particular, the invention relates to a hydromate which enables the engine to be started by activating the switch with the spring drive when this pressure decreases by determining the pressure equilibrium position depending on the compression distance created by the pressure between the outlet and the tap.
