Full-circle Drip Irrigation Fan Spray Bubbler 24 Gph 1 Pk

The Raindrip 15300UB is an adjustable spray bubbler designed to convert existing 1/2-inch underground sprinkler systems to low-flow watering where a traditional drip circuit cannot be set up. This non-pressure compensating emitter releases water in a fan spray, full-circle pattern, making it ideal for watering groundcover, decorative grasses, flower and vegetable gardens, as well as trees and shrubs. By turning the dial on the bubbler, you control the water flow from a shutoff position (0 GPH) up to 21.6 GPH, allowing you to customize watering schedules for any season and plant size.

The bubbler is mounted on a 5-inch stake with a built-in 1/4-inch barbed inlet that connects directly to 1/4-inch supply tubing. Simply position the stake in the ground so the emitter can evenly water your plant's root zone. At 30 PSI, the fan spray pattern delivers a spray diameter up to 13 feet, and at the full operating range of 15–50 PSI, the spray can reach up to 62 inches in radius. The adjustable flow rates allow higher discharge when watering large plants and lower rates for smaller plants on the same circuit.
