Rain Bird's pressure regulation stems (PRS) save up to 1 gallon (3.78 liters) of water per minute.

We offer three perfectly matched combinations of PRS pop-up sprinklers and high-efficiency nozzles. Each combination ensures the best possible performance from your entire irrigation system. All while saving you additional water.
