Sprinkler &
Irrigation Repair
Services

A residential irrigation system consists of several interconnected components: the controller (timer), valves, pipes (mainline and lateral lines), and sprinkler heads or drip emitters. Understanding how these components work together helps homeowners identify problems early, reduce water waste, and extend the life of their system.

The controller is the brain of your irrigation system. It sends electrical signals to solenoid valves, telling each zone when to turn on and how long to run. Modern WiFi-enabled smart controllers like the Rain Bird ESP-TM2, Hunter Hydrawise, and Rachio 3 go further — they monitor local weather data, adjust schedules for rain and temperature changes, and allow remote control from your phone. In the San Gabriel Valley, where water costs average $6–$9 per hundred cubic feet and conservation mandates are enforced by local water agencies, smart controllers typically pay for themselves within 6–12 months through water savings of 30–50%.

Valves control water flow to each irrigation zone. Many residential systems use electric solenoid valves installed in underground valve boxes. Common problems include stuck valves, leaking diaphragms, corroded connections, and damaged wiring. We diagnose the system before recommending a repair or replacement.

Sprinkler heads come in two main types: pop-up spray heads (for small lawn areas under 15 feet wide) and rotary heads (for larger lawn areas). The most common spray head brands installed in San Gabriel Valley homes are Rain Bird 1800 series and Hunter Pro-Spray. For rotary coverage, Rain Bird 5000 and Hunter PGP rotors are industry standards. Sprinkler heads should be adjusted for proper arc, radius, and precipitation rate to prevent overwatering and runoff — a service Outright Landscape includes with every repair and installation.

Drip irrigation delivers water directly to plant roots through low-flow emitters, typically rated at 0.5–2.0 gallons per hour. Drip is the most water-efficient irrigation method, reducing consumption by 50–70% compared to overhead spray. Drip systems are ideal for garden beds, shrubs, trees, slopes, and narrow planting strips where spray heads would cause overspray and waste. We install pressure-regulated drip systems with inline emitter tubing (Netafim Techline or Rain Bird XFS) for consistent flow across elevation changes common on San Gabriel Valley foothill properties.

Broken or stuck sprinkler heads can result from mower impact, foot traffic, or age-related wear. Symptoms include heads that do not pop up, sideways streams, or misting. We match replacement heads to the system's pressure, coverage, and flow requirements.

Leaking or stuck valves can cause zones to run continuously or not at all. Diaphragm wear, mineral buildup, solenoids, wiring, and controller signals are possible causes. We diagnose the system before recommending a component repair or replacement.

Pipe leaks and breaks occur from root intrusion, soil movement, freeze damage (rare but possible in foothill areas during cold snaps), and age-related PVC degradation. Signs include unexplained wet areas, sinkholes in the lawn, unusually high water bills, or loss of pressure on one or more zones. We locate leaks using pressure testing and visual inspection, then repair with schedule 40 PVC and proper primer/cement joints for a lasting fix.

Controller or wiring problems cause zones to skip, run at the wrong times, or not operate at all. Common issues include failed controller backup batteries (causing program loss during power outages), corroded wire connections in valve boxes, and cut wires from digging or rodent damage. We troubleshoot controller and wiring issues systematically using a multimeter to test each station and wire run.

Uneven coverage and dry spots indicate misaligned heads, incorrect nozzle sizes, or pressure problems. Head-to-head coverage (each sprinkler head throws water to the adjacent head) is required for uniform watering. We audit your system's coverage and adjust head spacing, arc, radius, and nozzle selection to eliminate dry spots and reduce water waste.

Understanding irrigation costs helps San Gabriel Valley homeowners budget for repairs and plan system upgrades. These ranges reflect current pricing for licensed, professional installation by Outright Landscape:

Southern California's semi-arid climate makes water efficiency a critical concern for homeowners. The Metropolitan Water District and local agencies like Three Valleys Municipal Water District, San Gabriel Valley Water Company, and Azusa Light & Water enforce tiered water pricing that penalizes overuse. An efficient irrigation system is the single most effective way to reduce outdoor water consumption, which accounts for 50–70% of total residential water use in the San Gabriel Valley.

Smart controllers are the highest-ROI water conservation upgrade. By using weather-based evapotranspiration (ET) data to adjust watering automatically, smart controllers eliminate overwatering during cool or rainy periods — the primary source of residential water waste. Many San Gabriel Valley water agencies offer $50–$200 rebates for installing EPA WaterSense-certified smart controllers.

Proper scheduling is essential even with a smart controller. The San Gabriel Valley's clay-loam soil absorbs water slowly — watering too fast causes runoff. We program controllers with cycle-and-soak schedules: shorter run times repeated 2–3 times with 30–60 minute soak periods between cycles. This allows water to penetrate the root zone without surface runoff. Watering should occur between 4:00 AM and 9:00 AM to minimize evaporation loss.

Pressure regulation prevents misting and fogging that waste water. Most San Gabriel Valley homes have water pressure between 60–80 PSI — higher than the 30–45 PSI that spray heads and drip systems are designed to operate at. We install pressure-regulating devices at each valve or spray head to maintain optimal operating pressure and prevent atomization of water spray.
