Sprinkler head broken or leaking
Tools: trowel, pliers, old towel, flag or stake to mark the spot · Materials: replacement head of the same type and nozzle, riser or flex riser if the fitting is broken
Steps
- Run the zone and watch: a geyser means a broken head, a bubbling puddle means a cracked riser or pipe.
- Turn the zone off and dig a neat circle of turf around the head with the trowel, setting it aside.
- Unscrew the old head anticlockwise; if the riser comes with it, unscrew the riser from the pipe fitting.
- Screw on the new head (hand-tight plus a quarter turn), set it so the top sits level with the soil, and run the zone briefly to flush grit before fitting the nozzle.
- Backfill, replace the turf, and adjust the spray arc and radius with the head's adjustment screw.
Stop and call a pro if
- water bubbles up between heads — a broken lateral pipe under the lawn
- the zone will not shut off — a stuck valve, not a head
- the controller shows a fault or a zone will not activate at all
What a pro does that you can't
An irrigation technician repairs broken laterals and valves, redesigns zones with poor coverage, and winterises the system where it freezes.
DIY cost: $3–15 for a head
