MPR heads are becoming a more popular option in irrigation. The MPR heads spray individual streams of water from each head, unlike a rotor or sprayer. It may take more time to water, but it allows the water to sit and soak in longer. Another benefit is being able to control the pattern of the spray to prevent excess water from being wasted. In most cases, these nozzles will fit on your existing irrigation heads, which makes for a simple conversion. Essentially, the MPR heads slow the whole process down and gives you a much more efficient and effective watering option.
