Shrub Riser & Shrub Adapters

Sprinkler head risers are necessary to irrigate plants that have grown taller over time. They can also help ensure proper water distribution in landscapes with obstacles like shrubs, flowers, or decorations.

Shrub risers commonly come in ½-inch male threaded sizes to fit standard irrigation fittings and sprinkler heads. They’re available in several lengths, typically ranging from 2 inches to 24 inches. The different lengths allow you to raise the sprinkler nozzle above plants or ground cover for proper water distribution. At Sprinkler Warehouse, we have dozens of shrub risers and adaptors from all kinds of dependable brands, like Aqualine.

Yes, a pop-up sprinkler will often suffice instead of a riser. Pop-up sprinklers stay flush with the ground when off and rise when watering, making them ideal for lawns and areas with foot traffic. However, shrub risers are better for flower beds or dense vegetation where the nozzle needs to stay high enough for proper coverage.

Some shrub risers are adjustable, but many are set at a fixed height. Fixed risers come in preset lengths and can be changed by replacing the riser or adding threaded extensions. After choosing a riser, avoid setting it so high that it becomes unstable or sprays outside the landscape bed.

Sprinklers on shrub risers should be spaced based on the spray nozzle’s radius, not just the riser height. In most cases, use head-to-head coverage, meaning each sprinkler should spray far enough to reach the next sprinkler. This helps prevent dry spots and uneven watering.

Raising the height of a sprinkler head can slightly reduce water pressure due to the added vertical distance. This effect is often minimal, but if your sprinkler system is already operating at low pressure, adding extensions could exacerbate the problem.
