![]() ![]() A pop-up spray jet consist of a narrow tube which rises from a larger tube when activated, which is similar to the pop-up sprinklers used in high pressure landscape watering systems. Another type, called a downspray, sprays water in a downward circular pattern. Another type of spray jet, called a strip jet, sprays water in two opposite directions for watering narrow strips of area. Spray Jet emitters spray water out to a larger diameter than typical drippers in arcs of 90, 180 or 360 degrees, and the flow rate is usually adjustable. Adjustable (stream), bubbler, and vortex drippers can be used for plants which require a larger wetting area than standard drippers can provide, such as plants with wide root zones or plants in larger containers. Some drippers even come with a built-in stake to secure it into the ground. Emitters with threaded ends are available to allow some types of drippers to be inserted into rigid 1/4 risers or into a hole drilled into PVC tubing. ![]() The inlet side of drippers is usually a barbed end designed to be connected to 1/4 tubing or inserted into a hole in the side of larger diameter tubing. A "vortex" type of dripper emits water in a steady circular pattern for a larger coverage area than a bubbler. A bubbler type of dripper produces a gentle umbrella pattern for rapid watering near the root zone. Some adjustable drippers emit water in several small individual streams out to a diameter from a few inches to a few feet in arcs of 360 degrees or 180 degrees. Typical drippers just drip water from the end. Adjustable drippers allow the user to vary the amount of water emitted, usually between 0 and 20 gph, by turning the dripper cap or a small valve.ĭrippers are available with varying patterns with which water exits the dripper. Pressure compensating drippers deliver a precise amount of water regardless of changes in pressure due to long tubing runs or changes in terrain elevations. A dripper that is not cleanable would need to be replaced if it becomes clogged. Cleanable drippers have a removable cap to allow the user to remove small obstructions within the dripper. Drippers are commonly used to water individual plants, and most drippers are color-coded so the user can easily identify the different flow rates. The most common emitter is known as a dripper or button dripper, and emits water at a specific rate, usually between. Since systems can be configured in many ways, it is not uncommon to find any combination of different types of emitters within a system. Emitters might also be imbedded within certain sizes of tubing, called drip tubing or drip tape, with the emitters spaced at specific distances apart within the tubing. Smaller tubing can also be installed between the mainline tubing and individual plants with emitters attached to the ends of the smaller tubing. This mainline tubing may have emitters attached directly to it at points adjacent to individual plants. In a typical drip irrigation system, tubing is laid out from the water source to the end of the planting area. ![]() By understanding the differences in emitter types, users can more easily select the right emitter for any application. Drippers, also referred to as emitters, are the end devices which deliver water to plants in a specific manner.
