Automatic timers

What they do

Automatic timers are not essential for a well-designed irrigation system, but they are highly recommended because they make watering your lawn much more convenient and efficient. Timers connect to the control valves and automatically start and stop the flow of water from the valves at preprogrammed times.

What to look for

Be sure to purchase a timer that allows different watering schedules for different areas of your yard. Turf will have different watering requirements from trees, shrubs, and other plants in your yard and it should be watered on a separate schedule.
