Dry spots or “striping” in the lawn
Often caused by clogged nozzles, misaligned heads, low pressure, or incorrect spacing. It can also happen when a zone is the wrong type (spray heads mixed with rotors) or when run times aren’t matched to how fast that zone applies water.
Mushy areas, puddles, or fungus around one head
Common causes are a broken sprinkler head, cracked riser, or a leaking lateral line. If you see water bubbling up while the system runs, that’s typically a sign of a break below grade.
Heads not popping up (or only halfway)
This points to low pressure, a partially closed valve, a pinched line, debris in the head, or a pressure issue in that zone. In some cases, it’s a symptom of a hidden leak stealing pressure.
One zone won’t turn off
Usually a valve issue (debris in the diaphragm, worn internals, or a stuck solenoid). This is one of the fastest ways to rack up water waste—so it’s worth addressing quickly.
Controller runs, but nothing happens outside
Could be a master valve problem, a shutoff left closed, wiring damage, or a mainline issue. If the controller “thinks” it’s watering but zones stay dry, troubleshooting should include both electrical and hydraulic checks.
