November rain sensors that stayed bypassed all year
A sensor switched to bypass in July is why the system ran through the first cold front. Put it back in the circuit and watch one storm.
A typical call sounds like this. In Gleannloch Farms, in April, before the turf hides every head, someone notices zones that start at the wrong hour on a shaded back yard. The rest of the yard, toward Spring Creek Oaks, still looks acceptable from the street, which is why the problem gets described as small. It is small only if the station, the valve, and the heads agree. We ask whether the wet or dry area changes while that station runs, and whether it continues after the clock moves on. Those two answers separate a nozzle, a valve, and a leak before we price a part. The soil under that lawn is a mix of clay and sandier forest soils, especially north toward the Woodlands line. The turf is mostly St. Augustine, sometimes Bermuda where the canopy opens up. A schedule copied from a different turf or a sunnier neighborhood will not survive contact with this yard. Water service here is municipal utility districts and private water systems that do not share one rule sheet. Any day-of-week rule has to come from the current notice for this address, not from a metro-wide chart.
Spring makes this specific
Spring yards share space with trees. Gleannloch and Windrose can look like a golf-community spec. Old Town and the wooded streets are roots, shade, and valve boxes that disappeared under mulch. A dry sunny strip and a sour shaded bed on the same station are a layout problem. Northgate and Spring Creek Oaks add newer pipe to that mix. Pressure and sun have to be looked at separately.
What the system is actually doing
The controller is the device everyone wants to replace first, and it is often the last thing that is actually wrong. A blank screen can be a tripped outlet or a failed transformer. A schedule that 'does nothing' can be a rain sensor that is still open, a rain delay counted in days, or a seasonal-adjust setting somebody dropped to zero. We read the display and bypass the sensor only as a test, not as a permanent condition.
When the clock runs a station and the yard does nothing, we separate the clock from the field. A click test, a voltage check, and a look at the master valve tell us whether the signal leaves the garage. If it does, the fault is wire or valve. If it does not, then we talk about programs, sensors, and whether the controller itself has failed.
Wi-Fi and smart controllers are useful when the zone data inside them is true. A weather adjustment cannot aim a nozzle, close a leak, or invent flow that a crushed pipe removed. If the garage has no usable signal, the clock should still be programmable from the face. Remote control is a convenience layered on top of a working conventional system.
We do not promise that a utility rebate is open for your address. Some Houston-area providers offer controller incentives some years and not others. Check the provider on your bill before you buy hardware for a discount that may not apply.
The ground under Spring
Spring yards share space with trees. Gleannloch and Windrose can look like a golf-community spec. Old Town and the wooded streets are roots, shade, and valve boxes that disappeared under mulch. A dry sunny strip and a sour shaded bed on the same station are a layout problem. Northgate and Spring Creek Oaks add newer pipe to that mix. Pressure and sun have to be looked at separately.
Landmarks we use to talk about the route include Old Town Spring, Spring Creek, and the Gleannloch lakes. ZIPs we see often are 77373, 77379, 77388, though the utility on the bill matters more than the ZIP. Service is municipal utility districts and private water systems that do not share one rule sheet. If a drought stage or a day-of-week rule is in effect, it is the one that provider published for this address. Our guide to checking watering restrictions is a method, not a live legal notice.
A pass through Spring neighborhoods
These are the sections we mean when we say Spring: Old Town Spring, Gleannloch Farms, Windrose, Spring Creek Oaks, Northgate Crossing. A visit for this problem does not look identical in each of them.
Clocks in Old Town Spring fail in ordinary ways: a tripped garage outlet, a rain delay still counting, seasonal adjust left at zero, a sensor switched to bypass so long that nobody remembers. We read the display before we price a replacement. Municipal utility districts and private water systems that do not share one rule sheet rules also belong in that program, and they are checked against the current notice rather than a neighbor’s photo.
Gleannloch Farms is where a manual station start does nothing in the yard and the screen looks awake. That is a signal problem or a master valve, not a mysterious head. We meter the station output. If voltage leaves the clock, the rest of the search is in the field. If it does not, then the clock, the transformer, or the sensor loop is the conversation.
Two controllers show up in Windrose more than homeowners expect. An old unit in a closet still owns a valve the new Wi-Fi clock does not. Programs fight. We find every clock before we declare the new one defective. Wi-Fi in the garage is a separate question. A clock that cannot be programmed from the face is a poor fit if the signal is weak.
After storms, Spring Creek Oaks clocks come back at midnight because the time was lost. The valves are innocent. Reset the clock and the days, then watch one cycle. A battery or a non-volatile program would have prevented it. That is a settings repair. It is not evidence the yard piping failed in the same hour as the outage.
Northgate Crossing programs are often copied from a sunnier relative’s house. St. Augustine under local shade does not need that July runtime. We will change minutes after the hardware is proven, not before. A smart controller with wrong zone data just wastes water more consistently. The station map has to match wooded acreage-style lots, golf-community lawns, and older Spring houses with valves lost under years of mulch.
How the diagnosis runs in Spring
- Read the display: time, program, rain delay, seasonal adjust, sensor.
- Prove the outlet and transformer.
- Test one station’s output before buying a clock.
- Only then replace the controller and copy the station map.
- Walk the yard once with the new program.
That sequence is the same standard we use on sprinkler controller repair across the metro. The local part is the yard: Spring has wooded lots, established subdivisions, and newer developments where irrigation lines often share space with roots and changing landscapes.
What we will not pretend
A photograph is not a diagnosis. A water bill is not a location. A smart controller is not a new pipe. Brown turf is not automatically a dry zone: chinch bugs, fungal disease, urine, and shade all imitate missed irrigation, and missed irrigation imitates them. We can test coverage. A turf diagnosis beyond coverage may belong to someone else. Read brown patch or a sprinkler problem and chinch bugs or a dry zone before you drown a lawn that was not thirsty. We also do not publish a flat price for a leak we have not found. Access, the fitting, and the surrounding pipe change the job.
Hiring is regulated in Texas. Ask who will do the work and check the license. Ours is listed as LI 6529. The short version of what that license is for lives in what a Texas licensed irrigator does. Backflow devices protect the drinking-water supply. We do not bypass them to make a zone run. If your provider wants a test, what happens during a backflow test explains the idea without pretending every city uses the same interval.
Questions we hear on this job
Will a longer watering schedule fix it?
Not if the pattern is uneven or water is escaping. Extra minutes amplify a leak or a bad nozzle. We repair the fault, then set the clock to the turf and to your utility’s current rules.
How do I shut it off if water will not stop?
If you can do it safely, close the irrigation isolation valve near the backflow device. Turning off the controller does not stop a valve that is stuck open. Then call 346-642-6161 and say which part of the yard is wet.
Do you repair sprinkler controllers in Spring?
Yes. We schedule sprinkler controller repair across Spring, including Old Town Spring and Gleannloch Farms. Call to confirm the address is inside the current route. The listed license is Texas irrigator LI 6529.
