Why Is My Sprinkler Shooting Water Up Instead of Spraying?
A column of water shooting straight up means something came off, broke, or cracked. The three usual suspects are a blown nozzle, a snapped riser, or a cracked head body, and which one you have tells you how big the fix is.

The short answer
A geyser shooting straight up almost always means nothing is left to shape the water: the nozzle blew off, the riser snapped below it, or the head body cracked. Shut off the zone first, then look at what is still standing on the riser to tell which one you have. A blown nozzle is a five-minute swap; a cracked body or a riser snapped below the lateral pipe is a job for a pro.
Shut off the zone first
A geyser failure dumps water fast, often 5 or more gallons per minute on a typical residential zone. Shut off the zone at the controller now. If you can't reach the controller, close the main supply valve to the irrigation system. You can take your time on diagnosis after the water is off.
A vertical column instead of a spray pattern is the signature of a missing nozzle, a snapped riser, or a cracked body.
Cause 1: Missing or Blown Nozzle
The most common cause. The nozzle is the small plastic insert at the top of the head that shapes the spray pattern. If pressure spikes, the threads strip, or debris jams under it, the nozzle can pop off. With nothing shaping the water flow, you get a vertical geyser.
What you'll see: The threaded top of the head sticking up out of the ground with nothing on it. The head body itself is intact.
Fix: Replace the nozzle. On Hunter Pro-Spray or Rain Bird 1800 series heads, the nozzle threads on by hand. Match the existing pattern (quarter circle, half circle, full circle) and precipitation rate. The nozzle selection guide covers what to match.
Cause 2: Snapped Riser Below the Nozzle
The riser is the short piece of pipe that connects the head body to the lateral line below. If something hits the head hard enough (mower, vehicle, freeze damage), the riser can snap below the nozzle and the head body goes with it.
What you'll see: A stub of plastic pipe at lawn level with nothing above it. Water shoots straight up from the broken pipe end.
Fix: Remove the broken riser stub from the lateral pipe fitting (this can be tricky if the threads are stripped), thread in a new riser, and install a new head. For repeat snaps in the same spot, replace the rigid riser with a flexible swing joint. Stop raising risers explains why this matters.
Cause 3: Cracked or Sheared Head Body
The full head body itself fails. Could be freeze damage (water expanded in the body during a hard freeze and cracked the housing), age (UV degradation on old plastic), or a hard impact that cracked the body without fully detaching it.
What you'll see: The head is still in place but visibly cracked, leaning, or gushing water out of the side rather than the top.
Fix: Replace the entire head with a new body. If freeze damage is the cause, check the other heads on the same zone for hairline cracks they may also have. Sprinkler head replacement service.
What to Check Before You Walk Away
Once the immediate failure is fixed, take two minutes to check the rest of the zone. A geyser dumps a lot of water in the spot it hit, so:
Check for a soggy spot where the geyser was running. Water may have pooled or run into a low spot near the foundation.
Look at adjacent heads on the same zone. A pressure spike that blew one nozzle may have weakened seals on others.
Run the zone for two minutes after the fix to make sure no other heads are weeping, leaking, or misting.
When to Call a Pro
Call a pro if the riser stub is broken off below the lateral pipe (you'll need to dig to repair the connection), the lateral pipe itself is cracked (water keeps coming out even with the head off), or this is the third geyser in the same zone (the underlying pressure or wiring issue is what needs fixing, not the individual heads).

A broken head is a DFW-wide problem. See how a broken sprinkler head gets replaced in Plano, Allen, Frisco, or Richardson.
Frequently Asked Questions
Why is my sprinkler shooting up water and not spraying?
A geyser of water shooting straight up almost always means there is nothing slowing or shaping the water flow. The three most common causes: the nozzle is missing or blew out, the riser snapped off below the nozzle, or the entire head body cracked or sheared. All three look similar from above (a column of water) but the fix is different. Turn off the zone, walk over, and look at what is still on top of the riser to identify which one you have.
Should I turn off the sprinkler if it is shooting water up?
Yes, immediately. A geyser-style failure is dumping water fast (often 5+ gallons per minute) and the water is going straight up and back down, not where it is supposed to. Shut off the zone at the controller, or if you cannot get to the controller fast, shut off the irrigation system at the main supply valve. Then you can take your time identifying which component failed.
How do I tell if it is the nozzle or the whole head?
Look at what is sticking up out of the ground. If you see the threaded top of a head with nothing on it, the nozzle blew off. If you see a broken stub of plastic at lawn level, the riser snapped. If you see the head pulled out of the ground or visibly cracked at the body, the whole head needs to come out. The fix scales with the damage: nozzle is a 5-minute replacement, riser is 10-15 minutes, full head body is a longer job because the swing joint and lateral connection may have been affected.
Can I fix a broken sprinkler head myself?
A blown nozzle: yes, almost always, if you can find the matching nozzle (Hunter Pro-Spray, Rain Bird 1800 series, etc.). A snapped riser: maybe, if the riser threads in the lateral pipe are still intact. A fully cracked head body or sheared swing joint: usually a job for a pro because you may also need to repair the lateral pipe connection below ground.
How much does it cost to replace a broken sprinkler head?
Head replacement starts at $55 in DFW, and the price moves with head type, how many heads, and whether there is collateral damage (broken riser, stripped swing joint, sheared lateral). Most residential geyser fixes are simple replacements in the same visit. See the sprinkler head replacement cost guide for the full breakdown.
Why does this keep happening to the same head?
Mowers and vehicles are the most common cause of repeat damage. A head that sits too high above grade gets hit by mower decks. A head near a driveway gets hit by tires. The fix is to lower the head to flush with grade and replace any rigid riser with a flexible swing joint that absorbs impact instead of snapping. If the head is being snapped off by clay soil heave (Allen and Plano residential properties especially), the swing joint fix solves that too.
Sprinkler still shooting water?
Heads, nozzles, swing joints, and lateral fittings ride on the truck, so a blown nozzle, snapped riser, or cracked head body gets diagnosed and repaired once we have the failure located.
