From my report:
Note: Sprinkler systems are operated only in the manual mode only with the controller. The inspector does not inspect the automatic function of the timer or control box, the rain sensor or the effectiveness and sizing of anti-siphon valves or back flow preventors. Spray coverage for the sprinkler system was not verified as part of this inspection. Coverage should be monitored for the system and adjusted accordingly to ensure even watering of the landscaping.
Underground pipes cannot be judged for breaks or possible root intrusions.
