How To Find A Leak In Irrigation System

How to Find a Leak in Your Irrigation System

Detecting a leak early can save water and prevent damage to your landscape. Start with a visual inspection before moving to more advanced methods.

Conduct a Visual Inspection

Walk your property and look for unusually wet or soggy areas.
Check for spraying or bubbling water at sprinkler heads.
Examine valves and connections for visible cracks or damage.

Perform a Pressure Test

Turn on the irrigation zone and observe water pressure.
Listen for hissing sounds indicating water escaping under pressure.
Use a soil probe to pinpoint saturated ground away from emitters.

Check Your Water Meter

A water meter test is an effective way to confirm a leak when the irrigation system is off. This method helps isolate the issue from household plumbing.

Ensure no water is being used indoors or outdoors.
Locate your water meter and observe the leak indicator for movement.
Record the meter reading, wait two hours, and check for changes indicating a leak.

Isolate the Problem with Zone Testing

If previous steps indicate a leak but you cannot locate it, isolating individual irrigation zones is the most effective diagnostic method. This process narrows down the search to a specific section of your system.

How to Perform a Zone Isolation Test

Manually activate one irrigation zone at a time using your controller.
Observe each zone for several minutes, watching for low pressure or water pooling.
Mark any zone that shows signs of a leak for a more focused inspection.
For the suspect zone, walk its path and probe the soil to find the exact leak location.
