Irrigation repairs and troubleshooting

Find the cause of uneven coverage, dead zones, leaks, or a system that will not start or stop.

Quick answer

Sprinkler repair starts with identifying which part of the system is failing: the controller, wiring, valve, pipe, head, or water supply.

Signs this may be the issue

One zone will not run or will not shut off
Water sprays onto a driveway or misses part of the lawn
A soggy area, unexplained runoff, or unusually high use
A controller runs at the wrong time or shows an error

How diagnosis works

A useful diagnosis checks the reported zone and the parts that control it. That can include controller settings, wiring, valve operation, visible leaks, head condition, spray pattern, and available pressure. The exact checks depend on the symptom and system layout.

What can affect the repair

How many zones or components are affected
Whether the fault is accessible above ground or buried
Part compatibility, wiring condition, and water pressure
Whether a repair exposes a second failure

Repair or replace?

A repair may make sense when the rest of the system is serviceable and the fault is isolated. A larger redesign may be worth discussing when repeated faults, outdated controls, or poor coverage point to a system-wide issue.

Questions about irrigation repairs and troubleshooting

Can a sprinkler system be repaired one zone at a time?

Often, yes. A diagnosis should identify whether the problem is isolated to one zone or shared across the controller, supply, or wiring.

What should I note before requesting repair?

Record which zones run, what the water does, any controller message, and when the problem began. A photo of the controller label can also help identify the model.
