Notice when the water appears
Does the puddle form only while a zone runs, or does it remain after the system is off? A damaged sprinkler head, a connection, a valve, or another part of the system can cause water to show up in different ways. The timing is useful information, but it is not a diagnosis on its own.
Look for changes you can see safely
From the surface, check whether the head is tilted, cracked, missing, or spraying toward a sidewalk. Note whether the wet patch is close to a head or farther along the line. If water reaches a walkway, building, or electrical equipment, keep clear and seek professional help promptly. Do not dig near buried utility lines or attempt electrical repairs.
Share the location of the puddle, the zone number if you know it, whether water flows when the timer is off, and when you first noticed the change.
Avoid the “just run it longer” trap
Water lost through a damaged component will not improve coverage where the lawn needs it. Continuing to run a leaking zone can make the wet area worse. If you know how to stop that zone safely, do so; otherwise call for help rather than forcing equipment or guessing at a repair.
What happens next?
A service visit can trace the source and determine whether a head, valve, pipe connection, or another component needs attention. Ask for a clear explanation of the proposed fix before work begins.
