Blocked or tilted heads, mismatched nozzles, pressure problems, poor spacing and schedule or soil differences can all create dry patches.
Compare watering coverage across the lawn
Run each zone in daylight and look for blocked spray, a tilted head, a mismatched nozzle or water reaching the sidewalk. Also inspect soil moisture: a brown patch can reflect runoff or compacted soil rather than too little scheduled water.
Inspection and repair steps
- Map which zone serves the dry patch and observe its arc.
- Clean, raise or replace obstructed heads and compare pressure.
- Test distribution, adjust the schedule and recheck the lawn response.

Watering and maintenance resources
UC IPM advises checking uniform coverage when brown spots persist. UC Riverside County Master Gardeners recommend adjusting irrigation monthly as seasons change, which matters in Temecula’s warm inland climate.
Cost and next step
The repair cost depends on the fault, replacement parts, access and any digging or restoration needed. Ask for the proposed scope and estimate before work begins. Our sprinkler repair cost guide explains the main factors.
