A broken head, blocked nozzle, partially closed valve, pipe leak or too many heads for available flow can weaken a zone. Compare it with other zones first.
Compare one weak zone with the rest
Compare the weak area with another zone at the same time of day. Look for a broken head, unusually wet soil, clogged filters and a valve that is not fully open. Avoid widening spray arcs until the flow issue is identified.
Inspection and repair steps
- Check the irrigation supply and observe each zone separately.
- Inspect nozzles, head stems, the valve and suspected underground leaks.
- Repair the obstruction or leak, then confirm head rise and even coverage.

Watering and maintenance resources
UC Master Gardeners put it plainly: “Check the pressure.” Pressure changes can reduce efficiency; Rancho Water also advises checking for leaks and adjusting heads to cover plants rather than pavement.
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.
