Where are on-line/button emitters typically attached in an irrigation system?

1. At the base of water tanks

2. To the outside of the tubing wherever water is needed

3. Inside the mainline piping

4. Only at the beginning of the system

The correct answer is: To the outside of the tubing wherever water is needed

On-line or button emitters are specifically designed to be placed directly onto the distribution tubing, which allows them to release water at designated spots within the irrigation system. This placement facilitates targeted watering and ensures that plants receive the exact amount of moisture they need. Attaching emitters to the outside of the tubing is crucial, as it enables flexibility in adjusting the emitter's position based on the growing conditions of various plants. This adaptability is beneficial for effective irrigation design, allowing for optimal water delivery tailored to different landscape needs. Positioning emitters solely at one location, such as at the beginning of the system or inside the mainline piping, would limit their efficacy. Emitters need to be strategically placed to provide water directly at the root zones of plants across the landscape, enhancing overall efficiency and reducing water waste. By connecting them to the outside of the tubing wherever water is needed, the system becomes more efficient in delivering moisture to specific areas, promoting healthier plant growth.
