Raindrip adjustable bubblers are useful when watering small and large plants on the same circuit and are often Ideal for conjunction with Raindrip conversion devices when adapting underground sprinkler systems to micro watering. Bubblers can replace several drippers in large, round containers. Use when higher flow rates (up to 24 GPH) are desired. Convert existing underground sprinkler systems to low flow watering where a drip circuit can’t be set up. Stream spray with a maximum spray diameter of 3 inch at 30 PSI or for finer water droplets. These features allow the higher flow rates required when watering large and small plants on the same circuit.
