Common Sprinkler System Repairs We Handle
Certified Plumbing & Drain handles sprinkler system repair throughout the greater Sacramento Valley, covering everything from snapped heads and blown valves to full zone failures and controller wiring faults. If your irrigation system is wasting water, leaving dry patches, or just won't cycle, we diagnose the root cause and fix it correctly. We've earned 5 stars across 20 Google reviews, and Alice Espitallier put it plainly: Jose's team repaired her front and back sprinkler systems in two days. That's the standard we hold ourselves to. Call (916) 706-7460 and we'll tell you what we're dealing with before we touch anything.
Irrigation repairs vary considerably in scope. A single broken pop-up head takes minutes. A valve that won't open, a zone that lost pressure, or a controller that's misfiring can require more systematic troubleshooting through the backflow preventer, the manifold, and the lateral lines. What drives cost is the number of zones affected, how deep the lines are buried, how long the problem has gone unaddressed, and whether deferred maintenance has caused secondary damage along the line. We don't quote a flat number without seeing the system first, because a quote like that doesn't protect you. Every job is different. Contact Certified Plumbing & Drain for an accurate estimate.
What Usually Breaks First
Most sprinkler failures trace back to four components, and most of them don't require digging.
Sprinkler Heads
Heads crack from foot traffic, mower strikes, and settling soil. A damaged head either sprays in the wrong direction or won't retract, which drowns one zone while starving the next. Replacement is straightforward, but the head type, arc, and radius have to match the original design or you'll recreate the problem.
Control Valves
Valves are the most common source of zone failures. A valve that sticks open wastes thousands of gallons. One that won't open at all leaves a zone completely dry. The solenoid, diaphragm, and bleed screw each wear differently, so diagnosis matters before we order parts.
Controller and Wiring
A controller that displays correctly but won't trigger zones is usually a wiring fault, not a failed timer. Wire corrosion, rodent damage, and pinched runs near the manifold box are all common in systems that have been in the ground for a decade or more. We trace the circuit before replacing hardware.
Lateral Lines and Fittings
Poly pipe connections loosen over time, especially where lines angle around foundations or pass through clay soil that expands when wet. A slow subsurface leak can go months without showing up as a wet spot, but it will show up on your water bill. Our leak detection methods find pressurized lateral leaks without excavating the whole run.
Backflow Preventers
California requires a functioning backflow preventer on every residential irrigation system. A failed or leaking preventer isn't just an inefficiency issue. It's a code compliance issue. We inspect, repair, and replace backflow assemblies as part of any full-system service.
Pressure Problems
Low pressure causes heads to pop up halfway and mist instead of throw. High pressure causes misting at full arc and accelerates head wear. Neither is the irrigation system's fault, pressure regulation happens upstream. We check static pressure at the supply line before assuming the sprinkler system itself is the problem.
How It Works
Our Sprinkler Repair Process
- 01
System Inspection
We run every zone manually, check head throw patterns, listen for pressure anomalies, and inspect the controller output and valve manifold. No guessing. We map what's wrong before we quote.
- 02
Diagnosis and Estimate
You get a clear explanation of what failed, why it failed, and what it'll take to fix it. We give you the repair scope upfront. No hidden items added after we've opened the ground.
- 03
Repair and Zone Test
We complete the repair, flush the affected lines, and run a full zone test before we leave. Every head arc and throw distance gets verified against the original coverage pattern.
Quick Reference
Sprinkler Problems: What the System Is Telling You
These patterns have specific causes, and most are repairable without replacing the whole system.
- 01
One zone won't run
Valve solenoid failure or a wiring break between the controller and that zone's valve. Rarely the controller itself.
- 02
One zone runs continuously
Valve diaphragm stuck open or a debris particle lodged in the seat. Flushing often clears it; replacement is inexpensive if not.
- 03
Wet patches between heads
Subsurface lateral line leak. The wettest point is usually within a few feet of the fitting that failed. Pairs with our leak detection service for precision location.
- 04
Poor coverage across a zone
Pressure loss from a partially closed valve, a clogged filter screen, or a head that's sunk below grade. All three are field-repairable with the right parts on the truck.
Can a Plumber Fix a Sprinkler System?
Know the Limits
When Repair Is Right and When It Isn't
- 01
Repair Makes Sense
System is 10 years old or newer, failure is isolated to one zone or component, pipe material is still in good condition, and the controller functions correctly across other zones.
- 02
Partial Replacement Makes Sense
Multiple valves failing across a manifold, lateral lines showing repeated pinhole leaks in the same run, or a controller that can't hold programming. Replace the compromised section; keep what's working.
- 03
Full Replacement Makes Sense
System is 20-plus years old with original polybutylene laterals, the controller is no longer supported, and repair costs on any given call are approaching what a modern system would cost to install. We'll tell you honestly which category you're in. We don't push replacement when repair is the right call.
