Rotary/high-efficiency nozzles fit on most popup spray heads. Instead of a fixed stream of water, rotary/high-efficiency nozzles slowly deliver multiple rotating streams of water, reducing water waste. Because the water is applied more slowly, more water is able to soak into the soil.
Rotary/High-Efficiency Nozzle Benefits
- Reduced runoff on slopes and clay soils.
- Easy-to-install retrofits for pop-up irrigation heads.
- Increased radius range.
- Considerably less water flow per minute than conventional spray nozzles, reducing water use.
- Better coverage.
Irrigation Problem | Rotary/High-Efficiency Nozzle Solution |
---|---|
Rotary/high-efficiency nozzles distribute less precipitation, reducing runoff. | |
Rotary/high-efficiency nozzles distribute a wider stream of water, resulting in less drift from the wind. | |
Rotary/high-efficiency nozzles provide better coverage, which can help eliminate brown spots. | |
Rotary/high-efficiency nozzles have a stronger stream of water, which is able to reach taller plants. |
Rotary/High-Efficiency Nozzle Watering Times
Rotary/high-efficiency nozzles use less water than fixed spray heads, but they require longer watering times.
- Use the chart to determine the number of minutes to water each zone on the days you water. Remember, watering is not allowed between 10 a.m. and 6 p.m.
