Sprinkler System Repair
Sprinkler system repair is the core of what we do at Dave's Sprinkler Repair. A properly functioning irrigation system protects your landscape investment and conserves water — two critical considerations in Chandler’s desert climate. From simple head replacements to complex underground pipe repairs and leak detection, we address the full range of sprinkler system failures.
Key benefits of professional sprinkler repair
- Accurate root-cause diagnosis to avoid repeated issues.
- Correct parts and repair techniques that help prolong component life.
- Water savings from fixing leaks, aligning heads, and updating nozzles.
- Improved turf and plant health from consistent, even irrigation.
- Reduced risk of soil erosion and damage to hardscapes from uncontrolled leaks.
- Documentation for HOAs
Core services we provide
Broken or damaged sprinkler heads
Pools of water, missing spray pattern, uneven irrigation.
Replace head and nozzle, adjust elevation and arc, test zone operation. In many cases we upgrade heads to more durable models and recommend matched precipitation-rate nozzles to improve uniformity.
Clogged nozzles and filters
Weak spray, fountain-like bursts, or areas that receive no water.
Clean or replace nozzles and inline filters. If sand or sediment is common, install larger or better-quality filters.
Low pressure or surge conditions
Weak spray, rotor stalling, or short-cycling zones.
Pressure tests identify whether supply-side issues or local pressure are at fault. We may recommend pressure-regulating valves, pressure-reducing nozzles, or valves with proper orifice sizes.
Valve failure
Zone not activating, continuously running zones, or leaking valve boxes.
Test solenoid and diaphragm, replace failed components, or replace entire valve assembly as needed. We ensure valve boxes are clean and accessible to avoid debris-related failures.
Underground lateral or mainline leaks
Wet areas in turf with no visible source, unexplained high water bills, or heaving sidewalks.
Leak detection using sound and pressure methods, followed by targeted trenching or trenchless repair. Where pipe is aging or repeatedly failing, we recommend full replacement with higher-quality materials.
Low pressure or surge conditions
Intermittent zone activation, zones running at wrong times, or controller failure to communicate.
Inspect wiring runs, repair damaged cables, re-terminate connections, and test voltage at solenoids. We also inspect for rodent damage and provide robust repairs.
Our repair process
Comprehensive diagnostic
We start by checking the controller, activating zones, and walking the affected areas. This helps isolate electrical, valve, or hydraulic problems.
Component testing:
Pressure tests, flow measurements, and solenoid testing identify failing parts.
Clear estimate
We provide a clear, itemized estimate explaining recommended repairs, materials, timeframes, and warranty information.
Repair and verification
After approval, we perform repairs using quality materials, then test the entire system zone-by-zone.
Customer walkthrough
We demonstrate repaired zones and adjust the schedule with the customer present.
Frequently asked questions
How do I know if my sprinkler system has a hidden leak?
Look for unexplained increases in water bills, soft or spongy turf, or wet spots that persist between waterings. Our technicians use pressure testing and acoustic detection to locate leaks precisely.
Are some repairs better than others in terms of cost-effectiveness?
Yes. We prioritize repairs that restore reliability without unnecessary replacement of healthy components. However, for systems with recurrent failures or aged piping, replacement may be more cost-effective long term.
Can you repair a damaged mainline without tearing up my lawn?
We evaluate trenchless repair options such as pipe-patching or sleeve repairs. When trenchless methods aren’t possible, we minimize disturbance and perform neat site restoration.
