Find private lines before grinding
Treat irrigation as a separate private system
Public utility marking generally does not identify every sprinkler, drip, landscape-lighting, pool, or privately installed line. Property owners should share plans, valve locations, visible risers, and any known route near the stump.
Run the irrigation system before the work date when practical and check for existing leaks. Mark heads, emitters, valves, boxes, and approximate line paths with flags or paint that will remain visible.
- Sprinkler heads and lateral lines
- Drip tubing and emitters
- Valve boxes and control wiring
- Backflow, shutoff, and repair access
Decide whether the line will be protected, rerouted, or abandoned
A line crossing the stump or root flare may need to be shut off, rerouted, or repaired before the grinder can safely reach the desired depth. Do not assume the operator can see tubing hidden inside roots or soil.
When landscaping is being redesigned, it may be more efficient for the irrigation contractor to isolate or reroute the zone before stump work begins.
Confirm repair responsibility and testing
The quote should state whether irrigation protection, repair, or post-work testing is included. After grinding and cleanup, run the affected zone and inspect for leaks, pressure loss, damaged wiring, or buried heads before the area is covered.
Keep chips and loose soil out of valve boxes and drainage paths.

Common questions
Frequently asked questions
Will a public utility locate mark sprinkler lines?
Public locates do not identify every private irrigation or landscape system. Known private features should be marked and disclosed separately.
Should I run the sprinklers before grinding?
That can help identify existing leaks and confirm which heads, valves, and zones are active before work begins.
Can the grinder cut an irrigation line inside the roots?
Yes, hidden tubing can be difficult to see. The line may need to be isolated, exposed, rerouted, or accepted as a repair risk before deeper grinding.
Who repairs irrigation after stump grinding?
That should be agreed on in advance. Irrigation repair may require a separate landscaper or irrigation contractor unless it is specifically included.
What should I photograph?
Show the stump, valve boxes, heads, emitters, control wire, shutoff, visible line routes, and the full equipment access path.
