Ease of Installation to Your Existing System
Whether you have an established irrigation system or you are planning to install one, integrating a rain sensor is a straightforward process. Adding a rain sensor to your existing system is highly beneficial and can be done with ease.
Locate an Ideal Position:
Determine the optimal location for your rain sensor. It should be installed in an open area where it can accurately detect rainfall without any obstructions. Common locations include rooftops, fence posts, or any area with a clear view of the sky.
Turn Off the Irrigation System:
Before beginning the installation, make sure to turn off your irrigation system to avoid any accidental water flow during the process.
Mount the Sensor:
Depending on the type of rain sensor you have chosen, follow the manufacturer's instructions to mount it securely in the selected location. Ensure that it is firmly attached and positioned at the recommended height for accurate rainfall detection.
Connect the Sensor: If you have opted for a wired rain sensor, connect the electrical wires from the sensor to the appropriate terminals on your irrigation controller. Follow the specific wiring instructions provided by the manufacturer to ensure a proper connection.
Configure the Controller:
Once the rain sensor is physically connected, access your irrigation controller's settings and configure it to recognize and respond to the rain sensor's signals. This may involve adjusting the rain sensor's sensitivity or setting specific watering thresholds.
Test the Sensor:
After installation, it is essential to test the rain sensor to ensure its proper functioning. Activate the irrigation system and simulate rainfall by either manually triggering the sensor or using a simulated rain test feature, if available. Verify that the sensor successfully interrupts the watering cycle when it detects rainfall.
By following these steps, you can seamlessly integrate a rain sensor into your existing irrigation system, providing you with enhanced control and water-saving benefits.
Regulations Requiring Rain Sensor Usage
Several states have recognized the importance of rain sensors in conserving water and have implemented regulations that require their usage. These regulations aim to promote sustainable irrigation practices and reduce water waste.
It's important to be aware of any regulations in your state regarding rain sensor installation and usage. Some states that have specific requirements for rain sensors include:
Florida:In Florida, it is mandatory for all automatic irrigation systems to be equipped with rain sensors. This regulation applies to both residential and commercial properties.
Georgia:
Georgia also has regulations in place that mandate the use of rain sensors for automatic irrigation systems. These requirements apply to new installations as well as existing systems undergoing modifications.
