Irrigation System Diagnostic

Stop guessing what’s wrong with your irrigation system. Our irrigation diagnostics service evaluates your system as a whole—identifying leaks, pressure issues, coverage problems, and inefficiencies that impact performance. What to expect: Full system inspection, zone-by-zone testing, clear identification of issues, and professional recommendations. After your irrigation system evaluation, we provide straightforward options to repair, correct, or fully optimize your system based on your goals and budget, ensuring your landscape maintenance services are effective and efficient.

Leak Detection

Irrigation System Diagnostic

Underground leaks can go unnoticed for weeks, quietly eroding soil and draining your wallet. We deploy non-invasive diagnostic tools to locate subsurface water loss without unnecessary excavation.


Acoustic Listening Devices: We pinpoint underground pipe fractures by tracing the precise sound frequencies of escaping water.


Real-Time Flow Ana

Underground leaks can go unnoticed for weeks, quietly eroding soil and draining your wallet. We deploy non-invasive diagnostic tools to locate subsurface water loss without unnecessary excavation.


Acoustic Listening Devices: We pinpoint underground pipe fractures by tracing the precise sound frequencies of escaping water.


Real-Time Flow Analytics: Continuous data tracking isolates continuous meter-side vs. property-side loss.


Pressure Testing: System-wide pressure checks isolate whether the fracture resides in the high-pressure main line or a specific zone lateral.

⚙️ Zone Functioning & Valve Diagnostics

If a specific section of your lawn won't turn on—or won't shut off—the problem usually lies within the circuit or the automated zone valves.


Electrical Continuity Checks: We use multimeters to measure resistance from the controller terminal to the valve solenoid, catching short circuits and broken field wires.


Buried Valve Location: If your

If a specific section of your lawn won't turn on—or won't shut off—the problem usually lies within the circuit or the automated zone valves.


Electrical Continuity Checks: We use multimeters to measure resistance from the controller terminal to the valve solenoid, catching short circuits and broken field wires.


Buried Valve Location: If your valve boxes are lost or buried beneath dirt and turf, we use wire tracking locators to map out their exact coordinates.


Mechanical Valve Overhauls: We open valve bonnets to inspect diaphragms for tears, physical debris, or scale accumulation that prevents clean seals


When water pressure drops, sprinkler heads fail to pop up or distribute water evenly, leading to dead zones. We diagnose and balance hydraulic irregularities across your setup.


Main Line Static Pressure Checks: Using precise water pressure gauges, we verify if your incoming supply matches the system's design requirements.


Dynamic Zone Testing: We check working pressure at the furthest emitter to identify hidden blockages, line friction, or pipe sizing bottlenecks.

Uniformity & Coverage Assessments

A system can be fully operational but still leave dry patches due to poor distribution efficiency. We evaluate coverage maps to optimize head output. 


  • Sprinkler Head Alignment: We correct misaligned, tilted, or low-head drainage issues that disrupt spray patterns.


  • Nozzle Performance Auditing: We check for clogged orifices, mineral fouling,

  • Sprinkler Head Alignment: We correct misaligned, tilted, or low-head drainage issues that disrupt spray patterns.


  • Nozzle Performance Auditing: We check for clogged orifices, mineral fouling, or mismatched heads that break distribution uniformity within a zone.


  • Micro-Climate Adjustment: We evaluate if your turf and garden zones are properly segregated to avoid overwatering shady spots or starving sunny areas.
