General questions about sprinkler repair


  • How soon can you come out for a repair?

    For emergency water loss or severely broken lines, we typically provide same-day service when a technician is available. Routine diagnostics are often scheduled within 24–48 hours. Call (480) 694-1655 for exact availability.

  • What is the difference between a diagnostic fee and the repair cost?

    A diagnostic fee covers the technician’s time and tools to isolate complex problems. If you approve the repair, we usually apply that diagnostic fee to the final invoice. We provide upfront estimates for repair work so there are no surprises.

  • Do you offer discounts for recurring maintenance plans or multiple properties?

    Yes. We offer pricing structures for HOAs, property managers, and multi-property contracts. Regular maintenance plans often result in cost savings compared to frequent emergency calls.

  • How do you locate underground leaks?

    We use a combination of pressure testing, acoustic listening devices, and targeted excavation when needed. By isolating zones and listening for water noise, we can pinpoint leaks with minimal digging.

  • Can you fix a leak without tearing up my lawn?

    Trenchless options such as inline repairs or pipe sleeves are available in some cases. When trenchless isn’t feasible, we perform careful excavation and restore the area cleanly.

Controller, valve, and electrical questions


  • My controller won’t turn on. What should I check?

    First check the power source and any GFCIs. If the controller has a transformer, it may be a failed component. Our technicians will test voltage at the controller and examine power and wiring.

  • How often should I replace my controller?

    Controllers last many years, but technology improvements (such as smart controllers) may justify replacement. If your controller is failing or lacks features that save water, consider an upgrade.

  • Dead or unresponsive controller display
  • Incorrect programming causing overlapping schedules
  • Controller runs at odd hours or stays on too long
  • Failure to turn zones on or off due to controller relay issues
  • Controller not communicating with remote or sensor devices
  • How can I lower my water bill without hurting my landscape?

    Seasonal programming, smart controllers, matched precipitation-rate nozzles, and pressure regulation are effective. We also recommend soil moisture sensors to avoid unnecessary cycles.

  • Do you comply with local water use restrictions?

    Yes. Our team is knowledgeable about Chandler and East Valley watering schedules and will program systems to meet local ordinances.

Maintenance questions


  • How often should I have my system checked?

     We recommend a spring activation and inspection before peak summer operations and a fall check to prepare for cooler weather. Commercial systems may benefit from quarterly inspections.

  • What does a typical tune-up include?

    Head cleaning and alignment, nozzle inspection, valve operation check, controller programming review, brief pressure and flow checks, and any small adjustments needed to improve coverage.

    Yes. We stand behind our workmanship and offer warranty coverage on labor, and on select parts per manufacturer terms. Warranty details are included in your estimate.

  • re replacement parts expensive?

    Costs vary by part and system age. Solenoids and diaphragms are typically inexpensive, while valve bodies and pipe replacement involve higher material costs. We provide itemized estimates so you know exactly what you’re paying for.

Commercial and HOA questions


  • Do you provide documentation for HOA approvals?

    Yes. We prepare written estimates, scope documents, and post-work reports as required by HOAs and property management.

  • Can you coordinate large projects with landscape contractors?

    Yes. We frequently work with landscapers, irrigation designers, and property managers to integrate irrigation repair and upgrades into larger landscape projects.

Emergency and seasonal planning


  • What constitutes an irrigation emergency?

    Major water leaks, broken mains, or uncontrolled flooding from irrigation components call for immediate response. Call (480) 694-1655 for emergency dispatch.
