The D033, .5 GPH, is a pressure compensating spiked drip emitter with flow regulation devices that provide consistent flow over a range of pressures, and insect baffle to minimize blockages caused by insects. Pressure compensating emitters ensure even flow rates under widely varying pressures and topographical conditions. The drip emitters are available in .5, 1 and 2 GPH. Use these drippers for even, consistent water flow from each drip emitter along the line, regardless of water pressure fluctuations in the system. Used for nurseries, pots, and baskets in the landscape area, the spike dripper delivers precise amounts of water directly to the root zone of the plants.

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.
