If you have a landscaping sprinkler system, it’s important to know what types of sprinkler heads you use. Each type of head has its own unique characteristics that will affect your watering needs and results.
Static Spray Heads
Static spray heads are the most common type of sprinkler head used in a residential or commercial irrigation system. They are designed with various water delivery features, allowing you to set the pattern and radius of the water spray to target grass and plants in your yard. They are also easy to adjust so you can reduce spray distance if you want to avoid tripping hazards or areas you do not want watered, like sidewalks and driveways.
Pop-up sprinkler heads typically come in heights of two, four or six inches. They are designed to irrigate zones of turf, gardens and shrub borders. They are also good for irrigating ground cover and other areas where soil and thatch have built up. When shopping for a pop-up head, consider its height and how the body and nozzle will fit the area you plan to water. The higher the height, the greater clearance it provides for growing grass and thatch. If you plan to use a stationary head in a small lawn area, choose a model that sprays only one dedicated zone up to 15 feet away. Stationary heads are usually spaced close together, 18 feet apart or closer. For a larger yard, you might want to consider a rotating head that rotates between 45 and 360 degrees. These sprinkler heads are quieter than impact rotors and can have a radius of 18 to 55 feet, depending on the model.
Unlike static spray heads, which deliver water in a fixed pattern, rotor heads rotate as they spray. This allows them to cover a large area, making them ideal for landscaping with swaths of grass. They also are great for slopes, as they disperse water slowly to avoid runoff. They are a popular choice for Denver Water customers who want to reduce water use and conserve money by using less water on their landscapes. And while rotor sprinkler heads are effective for watering lawns, it’s important to select them correctly. Choosing the right nozzle for each zone will optimize water use intensity and prevent overwatering and wasteful runoff.
Gear-Driven Rotating Heads
Gear-driven rotating heads spray water in a more precise and even flow than other rotary sprinklers. These nozzles also cover more ground quickly and are perfect for larger lawns. In addition, these heads have a wide range of water pressure to operate and offer a lower precipitation rate than impact rotors due to their smaller radius. This is especially helpful in areas with less moisture. For example, the Dramm ColorStorm 4-Pattern Gear Drive Sprinkler is a great option for those looking for an easy-to-use circular sprinkler that has four different spray patterns. It’s lightweight yet stable, and easy to assemble and adjust.
