After irrigation
Wet ground after the sprinklers run
If the wet area follows an irrigation cycle, begin with the schedule and the affected zone. A tilted head, overspray, faulty connection, or a line issue can produce different visible patterns.
A short field sequence
Observe one cycle, then compare
- 1
Write down the zone and start time
If you are unsure which zone covers the patch, use the controller's normal instructions. Do not open electrical controls or valve assemblies. If the schedule is automatic, note the normal run rather than changing several settings at once.

Look from a safe distance while it runs
Note heads that do not rise, spray hardscape, tilt, or leave visible water around a head. EPA WaterSense recommends checking heads and connections during irrigation maintenance. Do not stand in moving water or near damaged wiring.

Look between cycles
Water pooling after the system is off may be a sign of an underground leak or a valve that does not close completely, but it is not conclusive. Record how long the pooling remains and whether it happens after every run.
Compare the timing
A useful clue is when the wet area starts
Water may be landing where it is not needed. Note the head, direction, and nearby hard surface; a visible spray pattern is not evidence of a buried-pipe break.
Photograph it from a safe distance and identify the zone. EPA WaterSense includes tilted or damaged heads and visible connection issues among items to inspect during sprinkler maintenance.
Record the delay and whether the area grows. Pooling between cycles can point to a system that needs inspection, but soil, slope, and earlier watering also affect how quickly water disappears.
Pattern ≠ diagnosis
What to tell an irrigation professional
| Observed pattern | Useful detail to record |
|---|---|
| Wet only while a zone runs | Zone number, run time and the nearest visible head |
| Still pooling between cycles | How long after shutoff; whether the edge is growing |
| Water on wall or pavement | Direction of spray and affected surface |
Before you call
Share these details
- Which zone ran and its normal start time.
- Whether the wet spot began during the run or remained afterward.
- What was visibly different at the heads or around the valve box, without opening anything.
- Photos from the same place before and after a normal cycle.
Ask the irrigation professional to inspect the system and explain what evidence supports any proposed repair. Do not approve excavation based only on a wet patch or a general online checklist.
