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.
