As Manny said TX has sop
(1) operate all zones or stations on the system manually;
(2) report as in need of repair deficiencies in water flow or pressure at the circuit heads;
(3) report as in need of repair surface water leaks, the absence or improper installation of anti-siphon valves and backflow preventers or the absence of shut-off valves;
(4) inspect and report as in need of repair deficiencies in the condition and mounting of the control box and visible wiring; and
(5) report as in need of repair deficiencies in the operation of each zone and associated valves, spray head patterns and areas of non-coverage within the zone.
(g) Specific limitations for lawn and garden sprinkler system. The inspector is not required to inspect the automatic function of the timer or control box, the rain sensor or the effectiveness and sizing of anti-siphon valves or backflow preventers.
Here is one statement that I have for irrigation systems:
How to Conserve Water Outdoors:
Use the principles of xeriscape (quality landscaping that conserves water and prevents water pollution) in your yard.
Plant native, drought-tolerant or adapted plants in your yard.
Water only in the morning, when evaporation rates are at their lowest.
Use sprinklers that throw big drops of water close to the ground. Smaller drops and mist often evaporate before they hit the ground.
Water only when your landscaping or lawn begins to show signs of stress – when it begins to wilt or discolor or when footprints are visible after you’ve walked on it.
When you do water, water deeply and infrequently to promote good root growth and healthy plants.
Use a broom to wash your driveway – not a hose.
Don’t water the walls, windows, doors, AC equipment, pavements or fencing. These systems do not require irrigation and may be adversely affected by this continued exposure.
Consult an irrigation specialist about conversion of the spray heads within 18” of the structure walls, windows, AC equipment, pavements or fencing that receive water impact during operation.
Remember that in this general location even foundation moisture should supersede all other irrigation considerations.
