How to Fix a Broken Sprinkler Head

A broken sprinkler head is the most common irrigation problem — and often the easiest to fix yourself. Whether it's cracked by a mower, clogged, or stuck down, here's how to identify the issue and replace a sprinkler head.

Spot the problem

• Geyser or spray everywhere: a cracked or broken head, often from foot or mower traffic.
• Won't pop up: debris or a worn head stuck in the down position.
• Weak or uneven spray: a clogged nozzle or filter.
• Misting: too much pressure, sometimes from a missing nozzle.

Replacing a sprinkler head

Replacing a pop-up head is straightforward: turn off the zone, dig out around the head being careful not to get dirt in the line, unscrew the old head from the riser (turn counterclockwise), and screw on a matching new head. Match the type (spray vs rotor), pop-up height, and nozzle pattern to the rest of the zone.

Clearing a clog

If the head isn't broken, the nozzle or filter may be clogged with grit. Remove the nozzle, rinse it and the small filter screen beneath it, and reinstall. Hard-water mineral buildup can also block nozzles — soaking them clears it.

Adjust and test

After replacing, run the zone and adjust the spray pattern and radius so it covers its area without spraying the sidewalk or house. Make sure the new head matches its neighbors for even coverage. For widespread head problems or pressure issues, our irrigation team can help.

Frequently asked questions

Can I replace a sprinkler head myself?

Usually yes — it's one of the most DIY-friendly irrigation repairs, requiring just a matching head and a few minutes.

Why does my sprinkler head leak at the base?

Often a cracked head or riser, or a worn seal. Replacing the head typically resolves base leaks.
