Choosing The Right Type Of Sprinkler Head

When it comes to your sprinklers, the type of heads you have matter. The heads, or emitters, are what delivers the water to your lawn. Whether you are replacing the current heads on your system or simply designing a new system, the following guide can help you better understand your sprinkler head options.

Fixed Heads

Fixed head sprinklers do not move. Instead, they are set in a specific spray pattern – a full circle, half circle, or quarter circle – depending on where they are placed. For example, a full circle in used in the center of the lawn, while a half is used along an edge and a quarter is placed in a corner. Depending on the brand, these are available as preset or they may be adjustable so you have full control over the coverage area.

Choose fixed heads if the following apply to your situation:

  • You have relatively high and consistent water pressure, so the area of the spray doesn't experience any variance.

  • The area to be watered is small. Fixed sprinklers come in many coverage sizes, including those that limit their spray to a small area.

  • Are the head adapters on your main sprinkler line spaced closely together? If so, your system was likely designed for spray nozzles. Although you can opt for rotary, you will need to measure carefully and cap off extra adapters.

Rotary Heads

These heads are driven by pistons or gears inside the sprinkler. The flow of water sets these into motion so that they rotate, sending a spray back and forth over the lawn. Much like fixed heads, they can be set to water a specific area, but the setting options are broader. This means you can set them to water between any two points on a 360 degree circle.

The following are reasons that rotary heads may be the better choice:

  • You have an oddly shaped area to water and you don't want overspray outside of this area.

  • If low water pressure makes it difficult to have a consistent spray over a large area, consider rotary sprinklers. Rotary sprinklers concentrate the water into a single stream, so they can deliver it the proper distance without the need for high inherent water pressure.

  • When the sprinkler line adapters are spaced far apart, rotaries may be the only solution. You generally need less rotary heads since they move to cover a larger area.
