Use PVC or polyethylene pipe based on local conditions. Glue or crimp fittings securely and test each joint for leaks before burying.
Mount solenoid valves on a manifold and wire each valve to the controller using color-coded wires for straightforward troubleshooting.
Install sprinkler heads and drip emitters
Set sprinkler heads at proper height and spacing to ensure uniform coverage. Adjust nozzles for spray pattern and radius for efficiency.
For drip zones, install pressure regulators and filters. Place emitters near root zones and secure tubing to prevent sun damage and movement.
Wiring and mounting the smart controller
Choose a mounting location
Mount the controller near a power source and within Wi-Fi range. Keep it sheltered from direct sun and rain for durability.
Indoor mounting in a garage or utility room prevents exposure while keeping the controller accessible for manual overrides and wiring access.
Wire valves and power safely
Turn off breaker power. Connect common and zone wires to controller terminals, and attach the transformer to the power input securely.
Label each zone wire and test continuity with a multimeter. Proper wiring reduces false triggers and simplifies future maintenance tasks.
Connect sensors and accessories
Add rain, freeze, and soil moisture sensors to improve watering decisions. Connect sensors to designated controller inputs as per manual instructions.
Calibrate sensors through the app and test their function by simulating weather changes or moistening soil to ensure accurate readings.
Initial setup and app configuration
Create your controller account
Download the manufacturer’s app and register your device. Use a stable Wi-Fi connection and update firmware before proceeding.
Save login credentials in a password manager. Linking the controller to your account enables remote control, alerts, and analytics access.
Program zones and watering schedules
Set plant types, root depths, and sun exposure per zone. Use weather-based schedules to adjust runtimes automatically and conserve water.
Enable cycle and soak settings for deep watering without runoff. Review monthly adjustments to match seasonal plant needs and rainfall.
Test run and calibrate flow
Run each zone manually to check coverage and pressure. Adjust head positions, emitters, and run times for uniform soil moisture levels.
Monitor the app’s flow alerts and fix any leaks or clogs. Proper calibration prevents overwatering and protects plant health.
Maintenance, troubleshooting, and optimization
Routine seasonal checks
Inspect the system each season: clean filters, test valves, winterize in cold climates, and replace worn nozzles or tubing.
Record maintenance dates in the app. Regular care extends system life and ensures consistent irrigation performance throughout the year.
Common problems and fixes
If a zone fails to run, check breaker, transformer, and wire continuity. Replace faulty solenoids or repair crushed tubing causing low flow.
Address uneven watering by adjusting spray patterns or adding more emitters. Use pressure regulators to prevent misting and drift on windy days.
Use data to optimize watering
Leverage weather forecasts and moisture sensor data to refine schedules. Reduce run times after significant rainfall or during cooler periods.
Analyze monthly water use reports to find savings opportunities. Small adjustments often yield big reductions in water consumption and bills.
Costs, savings, and environmental impact
Upfront and ongoing expenses
Expect costs for controller, valves, piping, heads, and sensors. DIY installation cuts labor expenses while supplying higher upfront hardware costs.
Budget for occasional replacements, winterizing, and upgrades. Factor in potential rebates from utilities for smart controllers and water-efficient systems.
Estimate water and bill savings
Smart irrigation can cut outdoor water use significantly by using weather data and efficient emitters. Savings vary by climate and landscape.
