“The back zone had been dead since spring. He found a cut wire in the valve box, showed me where, and gave me the price before he touched it.”

The visit
What a service call looks like
- 01
You text or call
Send a photo of the controller, the valve box or the wet spot. Lucia or Roderick picks up, in English or Spanish, and books the visit.
- 02
Roderick walks every zone
He runs each zone from the controller, then checks the heads, the valves and the wire.
- 03
You get the price in writing
Before a part goes in, the repair and its price reach you by text. Say yes or say no; the service call stays the same.
- 04
It's fixed and tested
He runs every zone again with you, sets the schedule to your city's watering days and leaves a short note.
What's it doing?
Pick the one that sounds like yours
Most calls start with one of these six. If yours isn't here, text a photo and say what you see.
A zone won't turn on
A dead valve, a bad solenoid, a cut wire or a controller that stopped sending the signal. Roderick traces it from the controller out to the valve box.
A head is broken or won't pop up
Sunk, snapped, clogged or spraying the street. Roderick swaps or adjusts it so the water lands on the grass.
Water where it shouldn't be
A soggy patch, a wet curb or a zone that runs when it's off. A broken line or a stuck valve is almost always the cause.
The controller is blank or acting up
A dead display, lost settings or a schedule that ignores you. Roderick repairs it or fits a new one and sets every zone.
My backflow test is due
A yearly test of the assembly that protects your drinking water, with the report your water utility asks for.
Brown stripes and dry spots
Clogged nozzles, tilted heads and gaps in coverage. Roderick runs the zone, finds where it falls short and fixes that spot.
Text a photo
Text a photo of the controller
Often the screen tells Roderick what the repair is before he drives over. It also lets him bring the right part.
What to photograph
The controller screen, with any message on it
The inside of the controller, where the wires land
The valve box with the lid off
The wet spot or the broken head

From the yard
What neighbors say
“I texted a picture of the controller and he knew from the screen it was the rain sensor. It was sorted on the first visit.”
“The backflow test came with the report my water utility wanted. I didn't have to fill in a thing.”
Sample reviews.
Backflow
The yearly test, done and filed
A backflow assembly keeps lawn water from running back into your drinking supply. Ask your water utility whether yours needs a test every year.
Roderick tests the assembly with his own gauge, fills in the form, and sends it to your utility. If it fails, he tells you why and what the repair costs before he starts.

Quick answers
Before you call
Do I need to be home?
Not for a repair you've approved by text, as long as the gate is unlocked and the pets are inside. Roderick texts you when he arrives and when he leaves.
Can you work in the rain?
Light rain is fine. Heavy rain or a hard freeze moves the visit, and Roderick tells you when.
Do you install new systems?
No. This shop repairs systems that are already in the ground and tests backflow assemblies. For a new system, Roderick will point you to someone who installs.
Does my system need a backflow test?
Many Texas water utilities ask for one every year. Check with yours, or text a photo of the assembly and Roderick will tell you what he sees.
Not sure what it is? Send a photo.
A photo of the controller usually tells Roderick the next step.
Roderick or Lucia answers, in English or Spanish.
