The types of heads utilized on a specific project are determined by the dimensions of the area being covered, the water pressure available for operation, and a variety of other factors.
Sprays, Rotors and Accessories
Sprinkler heads come in a variety of sizes, shapes, models, and brands but most of these variations fit into four main categories: Pop-up, Impact rotors, Gear-Driven rotors, and Large Turf rotors. An overview of the different types and uses of spray heads, rotors, and impact sprinklers.
Spray heads are pop up bodies or shrub heads that are designed to be fitted with a spray nozzle or rotary nozzle. Installed below the ground, the sprinkler head remains out of sight while inactive. Once the sprinkler system is turned on, a small portion of the head will emerge above the surface to disperse water to the irrigation area.
Rotor heads are used to cover larger areas of un-interrupted space. Small rotors tend to cover radii of 15-52 feet and large rotors can be designed to cover radii of up to 100 feet. To operate efficiently, rotors need to be supplied with more water pressure than spray heads. The PSI level should approximately equal the space between each installed unit. There are two basic types of rotary heads, categorized by the mechanism that causes the sprinkler to rotate.
Impact sprinklers are available from a variety of manufacturers for any application. Sprinkler Warehouse offers impact sprinkler heads designed from the most durable materials, including brass, stainless steel, and plastic. Impact sprinklers are carried in full or partial-circle models, and will keep your landscape green and beautiful year round. Riser-mounted impact sprinkler heads are the perfect option for slopes, large areas, and above-grade applications.
Rotary Nozzle Sprinklers
Rotary Nozzles are multi stream nozzles that rotate similar to a rotor but provide a more efficient water distribution from 13 to 24 feet. They help reduce water waste and run-off on slopes and hard clay soils, with 25%-35% less run time than standard nozzles. Some products in this category are just the nozzle, which will need to be combined with a pop-up or shrub stick to be complete. Some products in this category include the spray head (aka pop-up body). The description will tell you whether the spray head is included.
Fixed (Shrub) Heads
Shrub heads are available in rotors and spray heads. Installed above the ground on a riser, this sprinkler design should be utilized if you need to provide water to high-reaching plants. These should only be located within flowerbeds and similar areas where foot traffic does not occur. If you need place a sprinkler in the lawn or a foot traffic area that services a tall planting or shrubs, taller pop-ups are available to serve this function.
