High-Volume Irrigation for Trees, Shrubs, and Large Containers
Take complete control of your spring garden’s hydration with the versatile Adjust-A-Bubbler. Also known as the Antelco Mini Bubbler, this high-volume drip emitter provides a full 360° umbrella of gentle streams, making it the perfect solution for thoroughly watering the root zones of new trees, established shrubs, and thirsty hanging baskets. Featuring an intuitive click-indexed cap, you can easily dial the flow from 0 all the way up to 35 GPH. Whether you are inserting the barb model directly into 1/2″ mainline tubing or using the 5″ spike model to secure coverage exactly where you need it, this adaptable bubbler drastically reduces watering times while ensuring deep, life-saving root saturation.
- Precise Flow Control (0-35 GPH): The fingertip click-indexed cap lets you dial in the exact flow rate for everything from delicate seedlings to mature, water-hungry trees. You can even shut it off completely!
- Adjustable 360° Coverage: Rotate the cap to adjust the umbrella-pattern watering diameter from a targeted drip to a wide 1.9-foot circle (at 30 PSI), adapting to plants as they grow.
- Efficient, High-Volume Watering: The incredible 35 GPH high flow rate allows for significantly shorter watering times compared to standard low-flow drippers, ensuring deep soil penetration for healthy trees.
- Easy to Clean: Features a simple take-apart design. Just unscrew the cap to quickly clear any sediment or debris, ensuring reliable performance season after season.
- Durable UV-Resistant Construction: Manufactured from robust, UV-stabilized polypropylene to withstand harsh sunlight and adverse weather conditions.

Performance Data (Fully Open):
| System Pressure (PSI) | Max Flow Rate (GPH) | Max Throw Diameter |
|---|---|---|
| 15 PSI | 27.0 GPH | 0.69 ft |
| 20 PSI | 30.1 GPH | 1.05 ft |
| 30 PSI | 35.0 GPH | 1.89 ft |
Note: Recommended operating pressure is 15-30 PSI. Flow and diameter can be adjusted down to zero by rotating the cap.
Follow these easy steps to integrate the bubblers into your landscape.
Step 1: Punch the Mainline
Using a DripWorks key punch, create a clean hole in your 1/2-inch or 3/4-inch poly mainline tubing near the plant you want to water.
Step 2: Connect the Bubbler
If using the Barb model: Press the bubbler’s base firmly and directly into the punched hole until it snaps into place.
If using the Spike model: Insert a 1/4-inch transfer barb into the punched hole, attach a length of 1/4-inch micro tubing, and connect the other end to the bubbler’s stake barb.
Step 3: Secure in the Soil
For the spike model, push the 5-inch stake firmly into the soil near the root zone of your tree, shrub, or container plant.
Step 4: Adjust the Flow
Turn on your irrigation system. Rotate the textured click-indexed cap counter-clockwise to increase the flow and umbrella diameter, or clockwise to reduce the flow to your plant’s specific needs.
