If installing an inground automatic irrigation system, follow these guidelines to optimize the system’s efficiency:

Properly install automatic rain sensor shut-off device and check regularly to ensure it is functioning properly.
Install a back-flow valve.
Separate zones for turf and non-turf areas.
Match precipitation rates on all heads within a zone (e.g., rotors and spray heads on separate zones).
Choose each device based on what will most efficiently water each group of plants.
Use pressure-regulated valve heads.
Use rotors in turf areas, spaced for “head-to-head” coverage.
Check valves on rotors and sprays in low-lying areas.
Verify that the system design meets state specifications for landscape irrigation installation as found in Florida Building Code, Appendix F.
Schedule appropriate irrigation that supplements rainfall to no more than 1.5 inches of water per week for turf areas, and less in planting beds.
Conduct regular inspection and maintenance to detect leaks, clean filters and realign or replace rotors and spray heads, as needed.
