If a sprinkler head is cracked, leaking sideways, or not popping up all the way, you can usually fix it in about 15 minutes with no special tools. The most common repairs — replacing a damaged head or clearing a clogged nozzle — cost $3 to $30 in parts. Here’s how to diagnose the problem, do the repair, and stop the cycle.
Sprinkler head repair is one of those things most homeowners put off because it sounds complicated. It isn’t. Once you’ve done it once, you’ll wonder why you ever paid for a service call.
The bigger issue isn’t the repair itself — it’s the cycle. You fix one head, a few months later the mower clips another, and you’re back at the hardware store. According to LawnLove, professional sprinkler head replacement runs $59 to $150 per head, including the service call. At that rate, a yard with 20 heads and a couple of mowing incidents per season adds up fast.
This guide covers how to diagnose what’s wrong, handle the repair yourself, and — more importantly — break the cycle.
What Causes Sprinkler Heads to Break
Most failures trace back to a handful of causes. Knowing which one you’re dealing with changes what you need to buy.
Mower and Trimmer Impact
Lawn mowers are the number-one cause of cracked and broken sprinkler heads. A wheel rolling over a pop-up head can bend the riser or crack the cap. A trimmer line catching the side of a head will snap the nozzle right off. If you heard a crunch sound while mowing, you already know what happened.
According to Texas Rainmakers, mowers and trimmers cause the majority of residential sprinkler head failures — more than soil settling, water pressure issues, and general wear combined. We cover the full breakdown in our piece on why sprinkler heads keep breaking.
Clogged Nozzles
If a head pops up but sprays in an odd pattern or barely reaches its usual distance, a clogged nozzle is the first thing to check. Dirt, debris, and mineral deposits from hard water are the usual causes. This one doesn’t require a replacement — just a quick clean.
Sinking or Misaligned Heads
A head that used to spray at the right height and now pops up below grade has sunk into the soil. Mower wheels rolling repeatedly across the same area, heavy foot traffic, and soil settling can all push heads down over time. For more on that problem specifically, see our guide on sprinkler heads that keep sinking.
General Age
Most sprinkler heads have a lifespan of 10 to 15 years under normal conditions. If your system is older than that and multiple heads are failing at once, you may be looking at a wave of end-of-life replacements rather than individual one-off fixes.
How to Fix a Sprinkler Head Yourself
Total time needed: about 10 minutes.
- Step 1: Run the Zone and Mark the Problem Head
Turn on the zone with the bad head just long enough to identify it. Mark the spot with a flag or rock so you can find it after the water shuts off. Then shut down that zone at the controller. If you're not sure which zone covers the area, shut off the main irrigation supply valve at the backflow preventer to be safe.
- Step 2: Dig Out the Area Around the Head
Use a hand trowel to clear the grass and soil from around the head — you'll need access to the body of the head and the fitting below it. Irrigation pipes typically run several inches underground, but risers and swing joints can be close to the surface. Work carefully and don't pry against the pipe.
- Step 3: Remove the Head and Inspect It
Most pop-up heads unscrew counterclockwise from the body. Some brands require a sprinkler key or flathead screwdriver to hold the body in place while you turn. Have a rag ready to catch any water in the line. Once the head is out, look it over closely. If the cap is cracked or the riser is bent, it needs a full replacement. If the head looks structurally fine, pull the nozzle out (it usually lifts straight up or unscrews from the top), rinse it under running water, and use a toothpick to clear the small openings. A surprisingly high number of "broken" heads just need a clean.
- Step 4: Install the Replacement Head
Take the old head to your hardware store and match the brand and series. Rain Bird, Hunter, and Orbit are the most common brands — and replacement heads cost [$3 to $30 per head](https://www.lawnstarter.com/blog/cost/sprinkler-repair-price/), depending on the type. Thread the new head in clockwise until snug. Don't overtighten. If the head sits too low after installation, you can add a swing joint or extension riser to bring it up to grade.
- Step 5: Test, Then Adjust the Arc
Turn the zone back on and watch the head through a full cycle. Confirm it pops up fully, covers its area, and retracts cleanly when the water shuts off. If the spray pattern is off, most nozzles have a small arc-adjustment screw on the top. Use the plastic key that came with the head (or a flathead screwdriver) to tune the arc left or right until coverage looks right.
When to DIY vs. When to Call a Pro
Most single-head problems are easy DIY work. A few situations are worth handing off.
| Situation | DIY or Pro? | Why |
|---|---|---|
| Single cracked head from mower impact | DIY | $3-$30 in parts, about 15 minutes |
| Clogged nozzle not spraying right | DIY | Free — just clean it |
| Head that won’t pop up fully | DIY | Usually debris in the body |
| Leaking at the base of the head | DIY | Loose connection or cracked riser |
| Multiple heads failing at once | Pro | May indicate a pressure or valve issue |
| Broken lateral pipe underground | Pro | Requires digging and pipe repair |
| Backflow preventer problems | Pro | Code-required certified testing in many areas |
| Full zone not activating | Pro | Controller, valve, or wiring fault |
For a single head, a pro visit runs $59 to $150 on top of the part. Do it yourself and you’re spending $12 on a head at the hardware store and 20 minutes in the yard.
Replacing worn nozzles or heads costs under $20 each. Routine maintenance tasks like adjusting heads and fixing leaks offer 20-30% water savings at minimal cost — versus $60 to $150 per head for professional replacement after damage occurs.

The Water Bill You’re Also Paying
Most homeowners focus on the repair cost and ignore the water cost. According to the EPA WaterSense program, a single damaged sprinkler head can waste up to 25,000 gallons of water per year. That’s water you’re paying for that’s going straight into the soil next to the head or spraying a fence instead of your lawn. Fix the head fast — the water bill savings alone usually cover the repair.
The Real Cost Over Time: Repair vs. Protect
| Approach | Year 1 Cost | Year 5 Cost |
|---|---|---|
| Ignore damage, keep calling pros | $150+ per incident | $750 or more |
| DIY repairs only, no prevention | $15-$30 per head | $60-$120 over 5 years |
| Protect heads first, DIY if needed | $6.50 per head upfront | Near-zero ongoing |
The cost math shifts once you add in prevention. A head that never gets hit by the mower is a head you don’t need to repair. That’s the part most people miss.
Stop Repairing the Same Heads Over and Over
If you’ve replaced a head in the same spot more than once, the repair isn’t the real problem — the exposure is. That head is sitting directly in the path of your mower wheels or trimmer, and it will keep getting hit until something changes.
What worked in my yard was the Sprinkler-Guard by GRASSHOLE. It’s a ring of Flexible Advance ABS with UV Deterrent that sits at grade around each pop-up head. When the mower rolls through, the wheel rides over the guard instead of crushing the head. The trimmer bounces off the side instead of snapping the nozzle. The head stays where it belongs.
Install takes about 30 seconds per head with no tools — just press the guard into place. You can even trim it to fit tight spots near edging or sidewalks. For a full breakdown of your protection options, check out our guide on how to protect sprinkler heads from lawn mowers.
If you’ve got a full yard to cover, the 20-pack at Sprinkler-Guard.com is the most popular option — covers most standard Sun Belt yards and brings the per-head cost down to $6.25.
Frequently Asked Questions
**DIY sprinkler head repair costs $3 to $30 in parts** per head, per [LawnStarter](https://www.lawnstarter.com/blog/cost/sprinkler-repair-price/). A standard pop-up head runs $8 to $15 at most hardware stores. If the head needs to be raised, add a few dollars for a swing joint or extension riser. Total job time is about 15 to 20 minutes once you've done it a time or two.
**Replace if the cap is cracked, the riser is bent, or water is leaking from the housing itself.** If the head looks structurally sound and pops up normally, clean the nozzle first — that fixes a large share of "broken" heads without any replacement at all. When in doubt, replacement heads are cheap enough that swapping beats spending time diagnosing.
**Yes.** According to the [EPA WaterSense program](https://www.epa.gov/watersense/sprinkler-spruce-up), a single damaged head can waste up to 25,000 gallons of water per year. Even a head that's simply spraying sideways instead of up will miss its target zone entirely — you're paying to water the fence or the sidewalk.
**Usually the mower or trimmer hitting it repeatedly.** If you've replaced the same head more than once, the head is being struck on a regular basis. Installing a Sprinkler-Guard around it stops the impact at the source. You can also check out the [most common reasons sprinkler heads keep breaking](https://grassholesystem.com/why-sprinkler-heads-keep-breaking/) to rule out pressure and installation problems.
**Match the brand and series when you can.** Rain Bird heads swap for Rain Bird, Hunter for Hunter. Thread pitch is often compatible across brands, but spray radius and arc differ between models. Mixing brands in a zone can create dry spots and overwatered areas. Bring the old head to the store to match it — that's the fastest approach.
Run the zone and watch where the water comes from — that marks each head's location while it's actively spraying. You can also walk the zone and press lightly on the ground after a rain; a slight give where the soil is softer often marks a buried head. For a full walkthrough, see our guide on [how to find hidden sprinkler heads](https://grassholesystem.com/how-to-find-hidden-sprinkler-heads/).
**No.** The Sprinkler-Guard sits at grade level around the base of the head. The head pops up through the center opening, completes its full spray arc, and retracts normally. The guard doesn't restrict water flow or change spray coverage. If a head is close to a sidewalk or bed edge, you can cut the guard to fit any shape.
The Bottom Line
Repairing a sprinkler head yourself is a 15-minute job that costs under $30 in parts. Identify the problem, shut off the zone, swap the head, test it. That’s the whole job.
What costs more is doing it every season because the same heads keep getting hit. A Sprinkler-Guard around each high-risk head stops that cycle. You can grab a 10-pack at Sprinkler-Guard.com and protect the heads most likely to get clipped — the ones closest to your mowing path — this weekend.
Not sure? The Sprinkler-Guard ships in 10/20/30/60-packs. If one ever takes too much abuse, you swap just that one in 30 seconds — no full system to replace.
