DIG’s Adjustable Stream Drip Emitters are available in a 180° or 360° pattern and with 1/4” barb or 6” spike. The adjustable Stream Drip Emitters are designed to produce a very low flow to gentle stream pattern with an adjustable flow of up to 14.1 GPH and a diameter of up to 2.3’ at 25 PSI. The adjustable stream drip emitters have a rotating cap that allows for simultaneous control of the flow and the wetted area. As your plants grow, they require more water to flourish and the flow and the area covered can be increased to support the plants’ growth. Used for an individual plant, group of plants, planter boxes, small to large pots, groundcovers, shrubs and trees, these adjustable drip emitters offer a convenient way to water areas where conventional sprinkler systems are not practical. Available in a wide range of pack quantities and configurations, including 360° Adjustable Stream Drip Emitters with ¼” barb, models B05B (pack of 5), B10B (pack of 10) and B25B (pack of 25), 360° Adjustable Stream Drip Emitters on Spike, model BA1B (pack of 4), B10B (pack of 10) and BA1PRO (pack of 25), 180° Adjustable Stream Drip Emitters with ¼” barb model B10C (pack of 10) and 180° Adjustable Stream Drip Emitters on Spike, model BA5C (pack of 5).

The 180° and the 360° Adjustable Stream Drip Emitters have a flow range from 0 to 14.1 GPH at a recommended preset pressure of 25 PSI. When the cap is rotated, the 180° and the 360° Adjustable Stream Drip Emitters flow and radius of the wetted area change from drip to a gentle stream pattern and then turn off as you rotate to close. This feature allows the user to adjust the flow to each individual plant as needed. Rotating the cap towards the “+” or the “-” signs allows the user to increase or decrease the flow rate. DIG’s 180° and the 360° Adjustable Stream Drip Emitters available with 1/4″ barb and a 6″ spike with a 1/4″ barb inlet and side barb. These Adjustable Stream Drip Emitters are ideal for watering a group of plants or under a large individual plant.
The 180° and the 360° Adjustable Stream Drip Emitters may be installed using one of two methods: either directly into the drip tubing or at the end of the micro tubing with each head placed under the plant canopy, at the center between the plant trunk and the plant canopy edge. The 180° and the 360° Adjustable Stream Drip Emitters on Spike are ideal when extended from the main poly drip tubing, and mounted about five inches above ground for good visibility. The 180° and the 360° Adjustable Stream Drip Emitters with barb can be mounted directly into the poly drip tubing. One of the most common installation errors is using too few drip emitters per plant. All too often only a single emitter is placed at the base of a newly planted tree or shrub. In clay soils, a single drip emitter can wet a three to four foot diameter; on sandy soils, the same layout using the same drip emitter will only wet an area less than one foot in diameter. Given the fact that plant roots can grow up to a few feet a year depending on the plant and location, after one year the diameter of the root area could be much larger than the area covered by the emitter. A single emitter per tree or shrub could restrict root development as early as the first year after planting if flow is not adjusted.
Basic installation recommendations for this product include first reviewing the area and then making a drawing of the garden or site with a layout. If automation is required, use one of DIG’s hose end timers or battery operated controllers, model B09D for a battery operated hose end and EVO100 for a solar powered hose end. For a valve box use our RBC7000 battery operated timer with a 3/4″ inline valve, for above the ground use our RBC8000 with 3/4″ anti-siphon valve. The ideal timer or controller should have flexible scheduling and two to four start times per day for added flexibility.
A common installation error installing a drip system is using a single drip emitter per plant. A single drip emitter placed at the base of a newly planted tree or shrub in clay soils can wet up to three-foot diameter, but on sandy soils, the same layout using the same drip emitter will only wet an area less than one foot in diameter. Because plant roots can grow a few feet a year, depending on the plant and location and after one year the diameter of the roots could be much larger than the area covered by single drip emitter. A single drip emitter per tree or shrub could restrict root development as early as the first year after planting if flow is not adjusted. By adding 2 to 3 drip emitters around the plant a better roots development can occur for better plants growth.
