The perfect overhead watering nozzle for foliage plants, bedding plants, geraniums and all 4 to 6 pot crops. Pin-Perfect Nozzles can be easily turned off by pushing the pin down and on again by pulling the pin up. Each nozzle produces a 10 foot diameter spray pattern when your water pipeline is 5 feet above the crop.
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.
Use Pin-Perfect Nozzles in combination with Dramm Run-Out Valves, No-Drip Risers and No-Drip Extension Check Valves to control water drip.
