These are usually what are most commonly envisioned when a homeowner thinks about a sprinkler system. These heads are dispersed around the lawn and in planting beds.
The spacing between sprinklers can vary depending upon the specific nozzle installed in the head, but they rarely are spaced further than 15 feet apart. Spray sprinklers installed in turf areas are designed to pop-up during watering and retract to below the turf line to allow mowing and normal use of the lawn after watering.
Spray sprinkler bodies are commonly available in various sizes, the difference being the height that the spray apparatus or nozzle is lifted above the body of the head. The high-pop-up models are used for flower and shrubbery bed areas where risers might be unsightly or subject to damage from passerby.
