Smart Means Matching Plant Need
WaterSense weather-based controllers use local weather instead of a fixed summer clock. Savings still depend on correct setup — broken heads and mixed plant types on one valve waste water with any brand.
Materials Required
- WaterSense-labeled weather-based controller
- Valves labeled by hydrozone
- Optional rain sensor
- Soil probe for moisture checks
Step by Step
-
Map hydrozones
Group similar water needs and sun. Do not leave lawn spray and drip shrubs on the same valve if you can split them.
-
Fix hardware before programming
Walk the system while it runs. Repair broken heads, overspray, and misting (often high pressure).
-
Install or retrofit the controller
Wire commons/valves carefully. Enable weather/ET mode rather than copying last summer’s minutes forever.
-
Enter landscape settings honestly
Soil, plant type, sun, and slope matter. Established woody plants often need far less than cool-season turf ET.
-
Verify with soil, not vibes
Probe after a week: irrigate near half depletion in the root zone. Adjust runtimes gradually.
San Diego Tips
- EPA cites about 7,600 gal/year average savings for WaterSense WBICs vs clock timers — results vary with setup.
- Cycle-and-soak on clay and slopes.
