If pressure falls above or below indicated values, Contractor shall notify Contracting Officer. For Irrigation Sprinkler System, indicate the following:a. Head, piping, valve, controller
42、, sensor layout.b. Pipe, valve, backflow preventer, and controller.*NOTE: Use the following in freeze-thaw climates only.*c. Invert elevations. Indicate obstructions interfering with operation.*NOTE: At the text below, if source of water supply is from station water system through a service line and
43、 water meter, determine amount of water required for station irrigation system from static pressure at point of connection of station main. These factors are essential in designing for system pressure. In many cases, water supply is adequate for short durations only. Provide adequate valves for each
