Plan Where the Pipes Will Go
Plot the underground location of the main pipe and zone pipe. In this demonstration, the first run will be the main pipe, which will go from the control box to the water meter. The second run will be from the street toward the backyard, where homeowners will eventually expand the irrigation system. All the zone pipe will connect with main pipe as well as to each sprinkler head. Each zone will have a separate valve box -- in this case, a total of four watering zones and four valve controls.
