Maintain Irrigation Efficiency

To maintain irrigation system efficiency, make sure that:

1. Valves are installed at lowest point(s) of each valve run.

2. Sprinkler heads and emission devices have matched precipitation rates.

3. Swing joints are installed on all risers in high traffic areas.

4. Overhead sprinkler systems are set back 24" from non-permeable surfaces (unless the non-permeable surfaces are designed and constructed to drain entirely to landscaping, and landscape area is adjacent to and drains to a permeable surface).
