A system and method for treating water to be used for irrigation. An input signal is received by a predistortion subsystem which applies deliberate predistortions to the input signal to arrive at a predistorted signal. Equipments in a network environment are placed on the first floor, the second floor, and the third floor in a building and connected through a network. The spacer contacts a surface of the rotary member facing a corresponding surface of the housing portion. The \u201cconfirm\u201d sound signals the start of the response time. The openings are positioned nearer to the lower edge than the upper edge.
