A head that sits in the can while the rest of the zone throws water is not always “broken.” In Texas clay the can fills with grit, the spring weakens, or the zone simply does not have pressure left after a leak upstream. Treating every stuck head as a $12 part is how dry corners last all summer.
This guide is written for Texas systems — expansive clay in master-planned lots in Katy, freeze risk in Plano, watering rules from City of Katy plus many MUDs. It is not a national blog with the city name swapped in. If the hardware is already failing, skip to sprinkler repairs or call 888-427-5022.
What a sprinkler head that will not pop up actually looks like on a Texas lawn
One head never clears the grass line; neighbors on the same zone look fine; or a whole branch of the zone is weak while the first two heads look heroic. Listen for the valve. If the valve is loud and the far heads are timid, you have a hydraulics problem.
In Katy the same symptom often traces to HOA coverage complaints and MUD watering windows. In Plano we see more freeze and heave. In Round Rock (City of Round Rock) the program may be legal but the heads are wrong. Do not assume the YouTube fix matches City of Katy plus many MUDs pressure.
Diagnose before you buy parts
Order of operations matters. Controller and rain sensor first, then the valve box, then heads with water on, then a shovel. Skipping steps is how people replace nozzles when the solenoid is open, or trench for a “root problem” when station 4 is dead at the clock.
- Pull the nozzle, rinse the filter screen, and check for a pebble stuck in the riser.
- Compare pop-up height to turf. St. Augustine eats 2-inch bodies.
- Read pressure at the first and last head. A 15 psi drop means a leak or undersized pipe, not a lazy spring.
- Confirm the station is actually on — a miswired solenoid looks like “heads won’t pop.”
- Only then replace the body, and match the nozzle chart to the head spacing you actually have.
Keep a notepad of zone numbers. The FAQ covers the phone questions we ask so the truck shows up with the right fittings.
Parts that actually last in this climate
Pressure-regulated pop-up bodies (30 or 40 psi) stop misting on Houston and SAWS mains that come in hot. Filters are not optional in well or MUD water. Keep a pack of matched nozzles in 8, 10, 12, and 15-foot; mixing is how you grow a wet stripe and a brown stripe.
We use matched-precipitation nozzles when we change a head, and we flush grit after a pipe cut so the next screen does not pack. Brand-specific notes live in the blog as well — start with Leaking Sprinkler Head, Sprinkler Zone Not Turning On, Sprinkler Zone Won’t Shut Off.
What it costs in Texas (ranges, not bait)
Screen cleaning on a few heads is a tune-up item. Replacing a body is still small. Rebuilding a starved zone because a lateral is crushed under a driveway is not a head job — get a leak and pipe quote.
A written quote before work is the rule. See Sprinkler Repairs for what a typical visit includes, and the full service list if more than one system is involved.
DIY vs calling a licensed irrigator
You can unscrew a nozzle and rinse a screen. If the body will not come up with the zone on and other heads are fine, the spring or wiper seal is done. If a row of heads is down, do not buy six bodies until pressure is measured.
Texas licenses landscape irrigators for a reason: backflow, buried electric, and municipal rules. If you are in Katy, Plano, or Round Rock, start on the city page — Katy, Plano, Round Rock — then book.
Mistakes that turn a one-hour job into a weekend
- Raising runtime instead of raising the head or fixing pressure.
- Installing 12-inch shrub bodies in turf “so they pop higher.”
- Ignoring a rain sensor that is stuck — the zone never truly runs.
How this ties to other repairs
Stuck heads after a freeze often mean the riser split below the can. Pair this with winterization reading if you are in DFW or the Hill Country. On the Gulf, grit after a storm is the usual story.
Coverage problems after a “fix” usually mean the program was never updated. Pair mechanical work with controller programming and, on clay, cycle-and-soak — not a longer single runtime.
What a good visit looks like on our trucks
We do not start with a parts cannon. Controller and sensor, then the box, then water-on, then dirt if the lateral is the problem. That order is how you avoid replacing a clock for a cut wire, or trenching a puddle that is eight feet from the break. If you want the short phone version, the FAQ is enough. If you want the long version, you are already in it.
Texas jobs change by metro even when the part number does not. Katy clay hides water. Plano actually freezes brass. Round Rock bills you through a different utility window. A national blog that only swaps the city name is how Google ends up indexing one page. We write the local constraint in the article because it changes the repair.
Bring zone numbers, whether the problem is new or slow, whether anyone dug recently, and whether the meter moves when everything should be off. Those four answers route the call — leak truck vs simple head work vs controller power path. Book on contact or call 888-427-5022.
Frequently asked
Should I oil the stem?
No. Grit plus oil makes mud. Rinse, replace seals, or replace the body.
All heads on one zone are weak.
That is valve, wiring, or a leak, not 12 bad springs. Isolate before you shop.
Need it fixed, not diagnosed over email? Call 888-427-5022 or use the contact page. Same-day windows are for active leaks and stuck-on valves. Everything else we schedule on emergency vs standard priority.
Texas context we will not skip
Gulf clay, Blackland prairie, and Edwards rock do not share a repair script. A wet spot in Houston is not a freeze crack in Dallas, and a SAWS stage day is not a MUD watering window in Katy. We write those constraints because they change the parts on the truck and the program we leave on the clock.
If this article is about a part, still run isolation before you buy a case of that part. If it is about a city, still open the valve box before you trench the first damp patch. If it is about a clock, still measure the solenoid. That order is the whole business.
