The black color D015 drip emitter with 1 GPH from John Deere Water is an easy to open and clean button online drip emitter with a consistent flow rate at 10- to 20 PSI. The drip emitter configuration have a few methods of installation options that including using the barb inlet to insert it into a 1/2" drip tubing or 1/4" micro tubing and in addition it has an 1/8” barb outlet that can be use with 1/8” micro tubing and a stake for potted plants production. The drip emitters have a unique labyrinth design, with a turbulent flow pattern that provides some resistance to clogging.

D014, D015 and D016 are small diameter drip emitters with features that surpass many of the drip emitters on the market today. Easy to clean and maintain, the line of button online drip emitters have a consistent flow rate at 10- to 20 PSI. The emitters have a unique labyrinth design, with a turbulent flow pattern that provides some resistance to clogging. The emitters are made of two parts that can be easily opened and cleaned. The emitters are available in .5, 1, and 2 GPH with a 1/4" inlet barb and 1/8” outlet barb. Use this drip emitter to ensure even, consistent water flow on a flat area. Used this line of drip emitters with flowerbeds, shrubs, trees, pots, baskets and vines by inserting the drip emitter directly into the 1/2" drip tubing or by extending the barb outlet with 1/8” micro tubing and securing the micro tubing with a stake part #A127. This configuration using the 1/8” micro tubing with stake can be also used with large number of small pots and baskets
The button online drip emitter will discharge the same amount of flow as is rated at a constant suggested operating pressure of 15 PSI. At higher pressure, more flow will be released from the dripper, and at lower pressure, less flow will be released. We recommend installing a filter and a pressure regulator at the beginning of the line with this drip emitter.
Drip irrigation is the slow application of water directly to the plants' root zone in a predetermined pattern. By preserving an optimum moisture level in the soil at all times, drip irrigation results in less water lost to the sun and the wind and less water wasted on non-growth areas. The resulting proper balance of water and air leads to very efficient irrigation.
One of the most important features of a drip irrigation system is the creation of a totally new and more favorable root zone environment within the planting. Drip irrigation sustains this environment by using low flow rates to maintain constant soil moisture levels. This encourages better growth and disease resistance by reducing plant stress.
To water a diverse selection of plant sizes such as trees, shrubs, bulbs and perennials, the option below can be utilized:
· Suggested number of drippers per plant:
o Vines with spacing of 6’- 8’ use 1 GPH per vine or 2, .5 GPH drip emitters spaced on each side of the vine with 8” to 12” between the drip emitters.
o Plants in close spacing: use a 1-GPH dripper every 10" to 12".
o Small plants up to 2 feet high spaced a few feet apart: use one 1-GPH dripper per plant.
o Plants 2' to 3' high: use 2 1-GPH drippers per plant spaced 12" apart.
o Plants 3' to 5' high: use 3 to 4 1-GPH drippers per plant, spaced 12" apart or loop the drip hose around the plant and insert the drippers every 12".
o Plant 5' to 7' high: use 4 to 6 1-GPH drippers per plant, spaced 12" apart or loop the drip hose around the plant with the drippers spaced 12” apart.
How much time to water: Turn the water on for 45 minutes to 1 hour every two to three days, depending on the drip emitter flow rate, your location and the soil type. After a week or two check the soil and the health of the plants, and adjust the irrigation time as needed. If you have an irrigation controller and you need to add more time, adjust the time on the controller or program the controller with additional start-times.
Note: Katif dripper models D043, D044 and D045 require the use of a punch with a 4mm tip.
