Control the amount of water delivered to your plants with a twist of a knob using the Adjustable Flow Bubbler. Bubbler works from 0-40 PSI to discharge 0-11.7 GPH with up to 16 in. radius. Water flow is easily adjusted to your preference by turning the dial from shut-off position to full coverage. The 8-stream emitter releases water in a full-circle pattern. Ideal for groundcover, decorative grasses, flower and vegetable gardens, as well as trees and shrubs. Built-in ¼ in. barbed inlet fits into punched hole in supply tubing. Bubbler is made of polyethylene treated with UV inhibitors. Drip irrigation systems are easy to customize, install, and operate. With non-pressure compensating emitters, expect varying water flows based on length of tubing or elevation, with higher flows closer to the water source. Adjustable flow bubblers are easy to set up in drip systems, and can be used in place of several drippers. Raindrip offers an emitter for every watering need. Raindrip is a leading manufacturer of drip and micro-irrigation solutions and the trusted brand of landscapers since 1972.
