Control Valve Installation & Repair
A faulty irrigation valve can flood your yard or leave zones completely dry. We replace, repair, and install control valves — and diagnose zones that won't switch on or off.
Most Repairs: Same DayWhat's Included
Whether it's a single valve repair or a full manifold upgrade, we handle all aspects of irrigation valve work.
- Valve diagnosis & inspection
- Solenoid replacement
- Diaphragm repair or replacement
- Full valve replacement
- Valve manifold upgrades
- New zone valve installation
- Wiring repair & connection check
- All zones tested after repair
Why Jaramillo Landscape?
Control valve problems can be tricky — a zone that won't turn on could be a bad solenoid, a wiring break, a controller problem, or a stuck diaphragm. We diagnose the actual cause, not just swap parts until something works. That saves you money and gets your system fixed right the first time.
We work with all major valve brands — Rain Bird, Hunter, Toro, Irritrol, and others — and carry common replacement valves and solenoids in our service vehicles. Most valve repairs are completed same day.
If you want to expand your irrigation system with a new zone, we can install additional valves and connect them to your existing controller, saving you from running a whole new system.
Our Process
We diagnose first so we're replacing the right part — not guessing.
System Assessment
We run all zones and check controller wiring to identify which valves have issues and what type of failure is occurring.
Identify Faulty Valve(s)
We test solenoids, check diaphragms, and inspect wiring to pinpoint the root cause of each valve failure.
Excavate Valve Box (if needed)
We locate and expose the valve box, clean it out, and access the valve for repair or replacement.
Repair or Replace
We repair what can be salvaged (solenoid swap, diaphragm replacement) or do a full valve replacement when necessary — always with a quality brand-compatible valve.
Test All Zones
Every zone is tested from the controller to confirm the repair is complete and no additional issues are present.
Typical Timeframe
Same Day
Most valve repairs and replacements are completed on the first visit. Complex manifold work or special-order valves may require a follow-up appointment.
Cost Factors
- Number of valves to repair or replace
- Valve type & brand
- Manifold complexity
- Wiring repair required
- Adding new zones vs. repairing existing

Frequently Asked Questions
A zone that won't turn on is usually a faulty solenoid (the electrical coil that opens the valve), a broken wire between the controller and valve, or a stuck valve diaphragm. We check each potential cause in sequence so we can fix the actual problem, not just swap parts randomly.
A zone that runs continuously is almost always a debris-fouled valve diaphragm or a failed solenoid that's stuck open. Debris from the water line gets caught in the diaphragm seat and holds the valve open even after the signal stops. This is a quick fix in most cases — cleaning or replacing the diaphragm.
Quality irrigation valves typically last 10–15 years with proper winterization. Solenoids may need replacement every 5–7 years. The most common failure accelerators are debris in the water supply, not winterizing properly (causing freeze damage), and UV exposure on valves that aren't buried in valve boxes.
Yes — we can add new zones to most existing systems by installing additional valves on the manifold (if capacity allows) or adding a valve off the main line. We'll assess your current system's water pressure to determine how many zones it can support before recommending additions.
