In general we try to run the irrigation at night. The best way to check the system is to check the soil first thing in the morning to see if it is moist. During the first few weeks we may run your irrigation system during the day and more frequently to help establish your grass.
The irrigation system is connected to one main line that runs around the entire project. A single nick at any point in the line can shut down irrigation for entire sections of the project. If you suspect something is wrong with your system please call customer service.
