Maintenance
The Rachio 3e Smart Sprinkler Controller requires minimal maintenance. Regular checks of your irrigation system components are recommended to ensure optimal performance.
- Inspect Sprinkler Heads/Emitters: Periodically check all sprinkler heads and drip emitters for clogs or damage. Hard water can lead to mineral buildup, especially in drip irrigation systems.
- Software Updates: Ensure your Rachio app and controller firmware are up to date for the latest features and performance improvements. Updates are typically managed automatically through the app.
- Winterization: If you live in an area with freezing temperatures, follow standard irrigation system winterization procedures to prevent damage to pipes and components. The app may offer features to assist with this process.
