Install above the surface or subsurface, the PC self-piercing drip emitter with barb from Netafim Irrigation is used with ease of installation without any tools or punches. The Self-piercing drip emitters are pressure compensating and operating between 10 to 50 PSI, providing the same flow from each emitter regardless of elevation or pressure fluctuation along the drip lateral. This self-flushing drip emitters with a check valve is built in with anti-siphon to prevents contaminates from being drawn into the drip emitters.
This range of PC drip emitters contain a diaphragm that continuously adjusts to varying water pressure to ensure a constant flow rate. The silicon diaphragm inside the PC drip emitter allows particles to pass through the drip emitters without harming it, providing reliable performance and a longer life. This method of continuous flushing and large flow path allows the drip emitter to operate at optimal flow rates under extreme conditions. The PC drip emitters discharge the same amount of water under a wide pressure range, providing high uniformity and longer run on any topography. This feature allows maximizing the amount of drip emitters on a single drip lateral while maintaining an even flow rate from each PC drip emitter. Use this type of drip emitters for any layout in home garden, commercial landscape and agricultural application.
Uniformity and lower maintenance:
With higher uniformity over a wide range of pressures, the pressure compensating drip emitters, offers many advantages in site preservation and maintenance, such as even uniformity over a longer lateral run with smaller size valves due to a smaller sized delivery system, resistance to clogging due to the water passage design.
Water movement in the soil:
When using drip emitters it is important to select the correct flow rate in order to achieve the right wetted pattern shape. In sandy soil, water tends to drain quickly (gravitational force) with little lateral movement, so applying a higher flow rate over a given time period will produce a wider pattern. Using point source irrigation with .5 GPH drip emitters for one hour will provide a smaller wetted area then using 1 GPH for the same time, due to the soil characteristics.
About drip irrigation:
Drip irrigation is the slow application of water directly to the plants' root zone in a predetermined pattern. Drip irrigation can be use to maintain optimum moisture level in the soil at all times that will results in less water lost to the sun and the wind. No water is wasted on non-growth areas, and the root zone is maintained at its ideal moisture level, combining the proper balance of water and air for a very efficient irrigation system. 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.
Installing Self Piercing Drip Emitters
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.
