Spring Action
Pop-up (fig. A)

Made from hard-bodied plastic with a spring inside. The pressure allows the spring to pop- up and when the water pressure is off the spring snaps the shaft back down inside.

Gravity Flow Pop-up (fig. B)

Pressure pushes the shaft up and gravity drops it back down. If the pressure is not maintained then gravity flow pop-ups tend to leak at the base.

Drip Emitters (fig. E)

Their job is to determine how much water will be used per hour.

Impact Sprinklers (fig. G, fig. F)

A type of impact sprinkler that's designed for the lawn comes in a cannister that allows it to sit in the ground (left, fig. B). The other type is designed for the landscape and it fits on a riser
(right, fig. F).

Multiple Spray Rotaries
(fig. c)

Uses less gallons per minute than the single spray rotaries. These sprinklers work best on a hill or slope where less water is required and reduced runoff is desired.

Shrub Adapter with Riser
(fig. D)

The shrub adapter screws into the 1 /2" riser. The nozzle simply screws onto the shrub adapter.

Single Spray Rotaries (fig. H)

Lets out a single spray and moves slowly to allow the water droplets to penetrate the soil. Rotary sphnklers are designed to cover large areas. They pop up above ground level.

WaterSavers & PCD'S

A WaterSaver is a plastic disk that is inserted into the bottom of a shrub adapter. Its functions are to stabilize water pressure, reduce fogging and reduce runoff. Pressure compensation devices (PCD's) are inserted into pop-ups and shrub adapters and have the same functions as WaterSavers.

** are available

Nozzles

Nozzles screw into the end of shrub adapters and pop-ups. Their function is to distribute water. Examples of the most common spray patterns are shown.
