Weak spray troubleshooting
Low pressure can come from a head, leak, valve, controller, or water-supply issue
A sprinkler zone with weak spray is a symptom, not a diagnosis. The cause may be simple, like a clogged nozzle or damaged head, or it may require checking a valve, solenoid, lateral line, controller wiring, or a hidden leak.
- Heads that do not pop up fully or spray only a short distance
- Dry spots even though the irrigation schedule is running
- One low-pressure zone while other zones work normally
- Sudden weak spray after mowing, edging, digging, or winter startup
- Pressure drop with wet spots, pooling water, or a bubbling head
- Multiple zones affected after controller, valve, or water-source changes
One zone or the whole system?
If only one zone is weak, the request may point toward a zone valve, broken head, clogged nozzle, or line leak. If every zone is weak, note any recent water shutoff, backflow, main valve, controller, or seasonal startup changes.
What to check before requesting help
Look for obvious leaks
Wet grass, a bubbling head, water near a valve box, or a soggy area can explain sudden pressure loss.
Note the affected zone
If your controller labels zones, include the zone number and whether the issue happens every run or only sometimes.
Check recent changes
New landscaping, mowing damage, freeze damage, controller edits, or a partly closed supply valve can all help narrow the issue.
