Raindrip Inc 15500UB Half Circle Stream Spray Bubbler

Product Description

The RAINDRIP INC 15500UB is a half-circle stream spray bubbler mounted on a stake, designed for low-volume drip and micro-irrigation systems. The bubbler head rotates to adjust water output across a continuous range of 0 to 20 gallons per hour (GPH), and can be dialed all the way down to a full shutoff position. This gives the installer precise control over flow without tools or additional valves. It is typically installed by irrigation contractors and landscapers, though experienced DIYers can work with it as well. The stake-mount design makes field placement straightforward in planting beds and container applications.

This bubbler is suited for residential and light commercial irrigation zones where targeted, low-volume watering is required. The half-circle spray pattern provides focused coverage for shrubs, large potted trees, and similar plantings where a full-circle emitter would waste water or oversaturate adjacent areas. It works within standard low-pressure drip and micro-spray systems and is packaged in a quantity of 100 units per pack, making it practical for multi-zone installs or contractor restocking.

Installation Notes

Installation is typically performed by licensed irrigation contractors or qualified landscaping professionals. Shut off the water supply and relieve system pressure before connecting or repositioning any emitter. Stake placement depth and spacing should follow the irrigation system design plan to ensure proper coverage overlap. Follow all applicable local codes and manufacturer guidelines for drip system operating pressure to avoid emitter damage.
