Precision Irrigation Repair Services
Accurate diagnostics, clean repairs, and long-term solutions for residential irrigation systems — from leak detection and valve issues to full system repairs done right the first time.
Smart Sprinkler Controller Installation
Control your irrigation system from your phone with a smart Wi-Fi controller. These systems can adjust watering based on local weather conditions to help improve efficiency and reduce unnecessary water use.
Irrigation Wiring Troubleshooting
Irrigation wiring issues can stop valves from opening, shut down entire zones, or cause inconsistent watering. We inspect the system carefully to locate damaged wires, faulty connections, or communication problems between the controller and valves.
Whether wires are chewed, cut, corroded, or improperly connected, we pinpoint the issue and complete the proper splices or reconnections using waterproof connectors built for underground irrigation wiring.
Full Valve Manifold Rebuild
Leaks beneath sprinkler valves are often a sign of a damaged PVC manifold. In many cases, spot repairs are not reliable, and a full rebuild is the most effective long-term solution.
We carefully inspect the system to identify the source of the failure and rebuild the manifold using properly fitted components, including new valves and anti-siphon assemblies where needed.
Sprinkler Controller Programming
If your sprinklers are running at the wrong time, not turning on, or watering too often, the issue is often incorrect controller programming. We set up your controller properly to match your system and landscape needs.
This includes adjusting start times, watering days, run durations, and seasonal settings to improve efficiency and prevent unnecessary water waste.
Sprinkler Valve Repair & Installation
Leaking or malfunctioning sprinkler valves can lead to water loss, poor pressure, and zones that fail to operate correctly. We diagnose the issue to determine whether a repair or full replacement is the best solution.
When replacement is needed, we install quality valves from trusted brands like Hunter, Rain Bird, and Irritrol — helping ensure reliable operation and long-term system performance.
PVC Pipe Leak Repair
Water bubbling under the lawn or near hard surfaces is often a sign of a damaged underground PVC line. Left unchecked, these leaks can lead to water loss, pressure issues, and property damage.
We locate the exact source of the leak and perform the proper repair using durable fittings and clean connections to restore system performance and prevent future issues.
Sprinkler Head Repair & Replacement
Dry spots, yellowing grass, or uneven coverage are clear signs your sprinkler system is not performing correctly. These problems are often caused by clogged, misaligned, or worn-out sprinkler heads.
We repair or replace sprinkler heads using high-quality components, including pressure-regulated pop-up sprinklers and properly matched nozzles to ensure even water distribution across your landscape.
Main Irrigation Shut-Off Valve
If your main sprinkler shut-off valve is not fully closing or begins to leak, it can make repairs difficult and lead to unnecessary water loss. A properly functioning shut-off is essential for controlling your irrigation system.
We replace faulty valves with durable PVC or brass options, depending on your system setup, ensuring reliable operation and proper control of your water supply.
In-Line Valve Repair
In-line valves that fail internally can allow water to pass through even when the system is turned off, leading to constant seepage, soggy areas, or water running into nearby landscaping or street areas.
We inspect key components such as the diaphragm, filter, and pressure regulator to identify the exact failure point, then repair or replace the valve to restore proper system control.
