Look for visible warning signs
Persistent puddles, water running down the street, misting sprinkler heads, soggy soil, and unusually green patches often point to pressure problems or leaks. Water on walls and fences signals poor alignment.
Compare similar plants
If one plant struggles while others on the same zone thrive, check its emitter and tubing. If an entire zone declines, inspect the valve, filter, pressure, and controller settings.
Review the water bill
An unexplained increase may indicate a hidden irrigation leak. Turn off indoor fixtures and watch the meter. If it continues moving, contact a qualified professional to isolate the source.
Run a monthly walkthrough
Operate each zone while watching it. Clean clogged emitters, replace damaged heads, straighten tilted sprinklers, and confirm that plant growth has not blocked spray patterns.
Watering rules, rebate programs, permit requirements, and product instructions can change. Confirm current requirements with the appropriate local agency or manufacturer.
