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.
The proper drip irrigation flow rates to use base on soil type:
When using drip irrigation it is important to select the correct application rate and spacing in order to achieve the right wetted pattern shape. In sandy soil, water tends to drains quickly (gravitational force) with little lateral movement, so applying higher flow rate using the same time period will produce a wider pattern. Using point source irrigation with .5 GPH drip emitter for one hour will provide a smaller wetted area then using 1 GPH for the same time due to the soil characteristic suggest.
To water a diverse selection of plant sizes such as trees, shrubs, bulbs and perennials, the option below can be utilized:
For maximum system expansion using a single water source, and to better control the system’s total flow rate, use .5 or I GPH (gallons per hour) drippers. We recommend using drippers with the same flow rate to resolve the difficulty of irrigating a garden planted with a diversity of plant types and sizes, for example a garden with trees, shrubs, groundcovers, bulbs and perennials installed on the same system. To increase the amount of water applied to larger or thirstier plants, simply add more drippers, at intervals of 12” around the plant. This drip irrigation method provides the plant with a larger wetted area to cover a larger section of the plant root zone. By adjusting irrigation time, the right amount of water can then be applied evenly to all the plants.
Suggested number of drippers per plant:
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 onfor 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.
