Pin-Perfect Nozzles should be installed on the topside of the pipeline or on top of 1/2 PVC risers. For uniform coverage, Pin-Perfect Nozzles should be spaced so that their spray patterns overlap. With the pipeline at 5 feet over the crop your Pin-Perfect Nozzles will produce a 10 foot diameter spray pattern. Space each nozzle 5 feet apart so the spray pattern will overlap to the next nozzle. Multiple pipelines should be spaced 10 feet apart for complete coverage. To decrease the spray diameter of the Pin-Perfect to 7 feet, lower the water pipeline to 3 feet over the crop and space the nozzles at 3 1/2 foot intervals.

To compensate for pressure loss and ensures uniform water distribution, simply change the color coded nozzle to the nozzle with the next higher output rate. This changing of nozzles will compensate for pressure loss and produce approximately the same amount of output all the way down the pipeline. As a rule of thumb, we recommend changing color coded nozzles every (6th) sixth nozzle.

Before you begin an installation, we recommend that you install one pipeline based on the guidelines presented. After the first pipeline is installed, tested and adjusted, remaining lines can be set-up following the same specifications as the first.

To provide uniform coverage the nozzles should be spaced so that their spray patterns overlap. With the pipeline 5 feet over your crop, Nifty Nozzles will produce a 10 foot diameter spray pattern. Space each nozzle 5 feet apart so the spray pattern will overlap to the next nozzle. Multiple pipelines should be spaced 10 feet apart for complete coverage. To decrease the spray diameter of the Nifty Nozzle to 7 feet, lower the water pipeline to 3 feet over the crop and space the nozzles at 3 1/2 foot intervals. Multiple pipelines should be spaced 7 feet apart for complete coverage.

For 'on-the-bench' watering (for cut flower crops), we recommend using lower flow rate Brown, Green or Grey Nifty Nozzles spaced 3 feet apart, one pipeline down the center of each bench or bed.

To Install, use a 7/16 drill bit to drill holes into schedule 40 PVC pipe, aluminum pipe or galvanized pipe. Caution: Do not use schedule 80 PVC. The Assembly Insert will not be able to create an effective seal due to the wall thickness of the schedule 80 PVC pipe.

Misty Mist Nozzles can be installed on the topside of the pipeline, on bottom side of the pipeline or on top of 1/2 PVC risers. Bottom side installations require No-Drip Check Valves to prevent drip.

To provide uniform coverage in overhead mist propagation or plug irrigation, the nozzles should be spaced so that their spray patterns overlap. With the pipeline 5 feet over your crop, Misty Mist Nozzles will produce a 6 foot diameter spray pattern. Space each nozzle 3 feet apart so the spray pattern will overlap to the next nozzle. Multiple pipelines should be spaced 6 feet apart for complete coverage. To decrease the spray diameter of the Misty Mist to 5 feet, lower the water pipeline to 3 feet over the crop and space the nozzles at 2 1/2 foot intervals. Multiple pipelines should be spaced 5 feet apart for complete coverage.

For raising humidity levels or mist cooling, use Blue/White Misty Mist Nozzles. It is recommended that you automate the system using short 'on' cycle times due the relatively high output rate of the nozzle. The pipeline should be suspended as high as possible in the middle of each bay without interfering with the spray pattern. Space nozzles 6 feet apart. There is no need to worry about overlapping spray patterns since the goal is to evaporate water into the air versus allowing the water to drop to the soil.

High Pressure Misty Mist Nozzles should only be installed on the topside of the pipeline. Bottom side installations are not recommended due to the high pressures involved.

Space nozzles 10 feet apart with the pipeline suspended as high as possible in the middle of each bay-- without interfering with the spray pattern of the nozzle. There is no need to worry about overlapping spray patterns since the goal is to evaporate water into the air versus allowing the water to drop to the soil.

Please note that high pressure pumps and filtration equipment are required for these nozzles to work properly. High Pressure Misty Mist Nozzles can not be installed using Assembly Inserts. Threads must be tapped directly into the water pipeline-- use the drill & tap installation method explained at the end of this section.

To provide uniform coverage the nozzles should be spaced so that their spray patterns overlap. With the pipeline 5 feet over your crop, Drop Inversion Nozzles produce a 24 foot diameter spray pattern. Space each nozzle 12 feet apart so the spray pattern will overlap to the next nozzle. Multiple pipelines should be spaced 24 feet apart for complete coverage. To decrease the spray diameter, lower the water pipeline until the desired spray diameter is achieved.

To provide uniform coverage the nozzles should be spaced so that their spray patterns overlap. With the pipeline 5 feet over your crop, Drop Upright Nozzles produce a 30 foot diameter spray pattern. Space each nozzle 15 feet apart so the spray pattern will overlap to the next nozzle. Multiple pipelines should be spaced 30 feet apart for complete coverage. To decrease the spray diameter, lower the water pipeline until the desired spray diameter is achieved.

To provide uniform coverage the nozzles should be spaced so that their spray patterns overlap. With the pipeline 5 feet over your crop and nozzles installed on the topside of your pipeline, T-Drop Nozzles will produce a 10 foot by 5 foot elliptical spray pattern. Space each nozzle 5 feet apart so the spray pattern will overlap to the next nozzle. Multiple pipelines should be spaced 5 feet apart for complete coverage. To increase the spray diameter of the T-Drop to 12 feet by 6 feet, install the nozzles on the bottom side of the pipeline and space the nozzles at 6 foot intervals. Multiple pipelines should be spaced 6 feet apart for complete coverage.

Hanging nozzle systems offer solutions to the traditional problems of rigid pipe mounted irrigation systems. Hanging nozzle systems use a check valve and hang below the lateral which prevents dripping from the nozzle or the 'shadow' dripping from the lateral. Dramm Hanging Nozzle Assemblies offer even watering. Gravity ensures that the nozzles are plumb preventing pattern distortion.

The entire assembly includes a leader tube with a barb fitting. The system uses flexible polyethylene tubing instead of PVC for ease of use and flexibility. A variety of leader tube lengths and nozzle choices are available. For flow rates see the specific nozzles.

To install a Dramm Pin-Perfect Hanging Nozzle System. Space the nozzle assemblies at 3' spacings . Choose a leader tube length that places the nozzles below the hanging baskets or at a height of at least 3' above the crop. Choose a Pin-Perfect Nozzle to suit your needs taking into account the flow rate of each nozzle and the flow rate of the lateral.

In addition to offering even watering, the Low Flow System promotes better wetting of the pot due to the lower flow rates. Because the water is released over a longer period of time, it does not run between the media and the pot like some high flow drip systems. This prevents water and fertilizer waste and promotes better growth of the plant.

The PCAS Drip Emitters use a silicone diaphragm to regulate the flow and prevent leaking. Besides offering excellent fertilizer resistance, the silicone diaphragms hold their shape well for long life. Other systems use EPDM diaphragms which are not as tolerant of fertilizers and other agro-chemicals and wear more quickly, requiring replacement. Additionally, silicone diaphragms are more flexible and allow for a wider range of pressures to be used with the SERYS emitter. Molded from durable polyamid plastic, SERYS emitters are UV stabilized and nearly indestructible.

The SERYS PCAS emitter uses a patented double cone lock connection that attaches the emitter to the lateral tube more securely preventing leaks that often occur with standard barb connections. (see drawing) PCAS Drip Emitters are designed to operate at pressures between 15 and 60 psi with an optimum operating pressure of 22.5 psi. Each valve opens at 6 psi and closes when the pressure drops below 3 psi.
