DIG’s 8855-1GB (in packs of 1) and 8855-5GB (in packs of 5) are 360° Micro Sprinklers with a double-frame design, completely assembled with a 13″ spike, 24″ micro tubing and a barb. The micro sprinklers’ spinner/rotor is balanced between the micro sprinklers’ double frame and the nozzle, providing gentle and consistent uniformity over a wide area of up to 25’ in diameter. They are a great choice for watering flowerbeds, groundcovers, vegetable gardens and under tree canopies. The micro sprinklers are pre-assembled with a spinner for 360° of coverage, and interchangeable spreader insert heads are included in the package for 90°, 180° and strip patterns.

The 8855-1GB and 8855-5GB Micro Sprinklers on Stakes are available in a complete assembly configuration with a 13” stake and 24” micro tubing with a barb. They are recommended for flowerbeds, vegetable gardens, seedlings, groundcovers and under tree canopies. The ideal spacing is 11’ to 15’ between the micro sprinklers to a maximum distance of 135’ in length, with 1/2” drip tubing used as the main lateral. Included in each package are interchangeable spreader inserts to reduce the coverage to half, quarter circle or strip pattern. The flow rate is 18.3 GPH at 25 PSI with coverage of up to 25’ full circle, or a 10’ radius, depending on the assembly of spreader inserts used and the height of the micro sprinkler.
The micro sprinkler design has the spinner/rotor mounted between the double bridge and the nozzle. The spinner/rotor can be changed by turning the nozzle assembly clock wise and removing the nozzle and the spinner/rotor.
The micro sprinkler on a stake operates with low flow at relatively low pressure compared to conventional sprinkler systems. Low-flow overhead irrigation with a low application rate can be used for areas where drip emitters are not practical, for keeping plant foliage constantly moist or when overhead watering is required. The micro sprinklers apply water to the surface area at a very light precipitation rate and at low tension to the soil, allowing the water to dissipate in a wetted profile that provides high uniformity. One of the main features of micro sprinkler irrigation is that it can prevent plant stress by maintaining low water tension in the soil, therefore leading to healthier plants, by using a low-flow application rate.
Basic installation recommendations for these products include first reviewing the area and then making a drawing of the garden or site with your preferred layout.
If automation is required, use one of DIG’s hose end timers or battery operated controllers. The ideal controller should have flexible scheduling options and two to four start times per day for added flexibility.
Step 1: Turn the nozzle assembly with the micro tubing counter clockwise and remove the nozzle assembly and the spinner/rotor mounted between the double frame and the nozzle assembly
Step 2: Insert one of the spreader inserts with the pin forced to the location on the double frame housing. Move the spreader insert into position by turning it left or right
Step 3: Insert the nozzle assembly with the micro tubing and turn it clockwise to lock
