The A450 Four-Outlet Drip Manifold Kit can be used on new or existing installations to convert a sprinkler riser into a drip irrigation system applying 50% to 70% less water than a conventional sprinkler system. The A450 applies water at the root zone area of the plant only, eliminating pest problems, weed growth, and water waste from evaporation and run off. The kit, recommended for watering individual shrubs, roses or trees, contains a pressure compensating four-outlet drip manifold for even uniformity from each outlet, 50' of 1/4" micro tubing, four stakes to secure the micro tubing and converter barbed elbows for each outlet. The four-outlet manifold can be used to cover individual plants or closely spaced groups of plants within the layout. This kit is a complete kit containing all the parts required to install a complete system.
The A450 four-outlet manifold can apply water to most landscape gardens utilizing the same short range watering cycles as used with spray heads to meet most watering applications. Using drip irrigation, water first thing in the morning before the temperatures begin to rise. This will allow excess moisture on leaves and top soil to dry before fungal and other diseases can develop. The most common cause of early plant death is over watering. Using drip irrigation can help sustain healthy plants by applying water directly to the plant root zone when and where it is needed. For established plantings, deep, infrequent watering is recommended. In most cases, applying deep watering will encourage deeper rooting, which leads to stronger, healthier plants.
Remove existing sprinkler from riser.
Screw on four-outlet drip manifold.
Insert each of the press-fit barbed elbows into the four outlets and connect the micro tubing to the barbs. Then connect micro tubing to barbs.
Run lengths of micro tubing to your plants, secure with tubing stakes.
A drip irrigation manifold is designed to convert a 1/2" sprinkler riser into a drip irrigation system. The drip irrigation manifold may be incorporated into a new system, or used to convert an existing sprinkler riser to a multi-outlet drip irrigation system. Retrofitting a conventional sprinkler riser to a water-saving drip irrigation system requires a few simple steps including evaluation of the areas to be watered and selection of the best method to water. The most suitable uses for a multi-outlet drip irrigation manifold are shrubs, trees, roses, pots or individual plants that can be irrigated more efficiently using a drip irrigation system.
- First, we recommend using the four-outlet manifold in an area where the plants are close to the sprinkler riser you are replacing. We recommend using shorter lengths of micro tubing, not exceeding six to eight feet from the riser, to allow for easy maintenance.
- Make sure that the output of the manifold is sufficient to cover the plants in the area close to the sprinkler riser.
- Remove the sprinkler from the riser.
- Turn the water on to flush the line. Then shut off the water and thread the multi-outlet manifold onto the riser.
- From the manifold outlets extend 1/4" micro-tubing to the plant areas. At this point you have a number of options:
- Secure the end of the micro tubing with the stake included in the kit. This option will allow for a flow of 6 GPH from each outlet used.
- To the end of the micro tubing insert a ~: barb (model H80 not included in the kit) and connect 1/4" drip line (model SH50 not included in the kit) or soaker hose (model PSH50 not included in the kit) and loop it around the plant. This option will provide a larger wetted area under the plant canopy and provide even water distribution from each of the four outlets. This option allows for five to six feet of drip line or soaker hose per each outlet.
- To the end of the micro tubing insert a 1/4" tee (model H82 not included in the kit). From the tee, extend additional lengths of micro tubing and insert a PC drip emitter or adjustable drip emitter (models B224B or B10B not included in the kit) with the drip emitters placed under the plant canopy, at the center between the plant trunk and the plant canopy edge.
- Connect the micro tubing onto the converter barbs, included in the kit, and insert each barb into one of the open outlets.
- Turn the water on and check the system, making sure that all outlets are working and the location of each outlet meets your needs.
Note: One of the most common installation errors is using too few, and poorly spaced, drip emitters. Often only a single emitter is placed at the base of a newly planted tree or shrub. In clay soils, a single drip emitter can wet three to four feet in diameter; on sandy soils, however, the same layout using the same drip emitter will only wet an area less than one foot in diameter. Because plant roots can grow a few feet a year depending on the plant and location, after one year the diameter of the root system might exceed the diameter of the watered area. A single emitter per tree or shrub could therefore restrict root development as early as the first year after planting. For this reason, it is especially important to place additional drip emitters around each plant, early in the plant's life.
Note: To expand the system we highly recommend continuing with the same model kit or products. Review the instruction manual included with the kit for complete details.
