Quick answer: Underground sprinkler leaks often reveal themselves through persistently wet soil, erosion, bubbling water, a weak irrigation zone, unusually green patches, or water surfacing only while a particular zone runs. Finding the affected zone first can greatly narrow the search area.
Run zones one at a time
Operate each zone separately and observe changes in pressure and ground conditions. If wet soil or bubbling appears only on one zone, focus on that zone’s lateral piping and fittings.
Signs of a hidden irrigation leak
- Heads suddenly lose spray distance
- Several heads fail to pop up
- Soft or saturated ground develops during watering
- Water bubbles from turf away from a sprinkler head
- Washout or erosion appears near piping
Do not assume every wet head is a pipe leak
Low-head drainage can allow water to drain from the lowest sprinkler after a zone stops. A valve that seeps can also create ongoing discharge. Timing and location help distinguish these problems.
