Our commercial grade drip irrigation micro dripper line is made of the highest quality resin. The micro dripper line with the pre-inserted drip emitters can be used as a feeder line from 1/2" poly tubing (drip tubing)or it can be used as part of a complete 1/4" drip irrigation system, using with 1/4" barbed fittings.

Both drip emitters and dripper line are manufactured from high quality material that can withstand chemicals and fertilizers. the non PC drip irrigation, dripper line discharge the same amount of water under a preset pressure range of 15 to 20 PSI.

When designing or installing a drip irrigation system for vegetable garden, green roofs, patios, containers, narrow plantings, large pots and boxes, our 1/4” drip lines should be on the top of your list. DIG’s Micro Line™ dripper line offers both installers and users a new and simple concept in drip line layout for above or below grade applications.

• Installation for Drip Line

  The micro drip line can be installed below or above the ground and if used above the ground can be covered with mulch to blend it with the landscape.  To connect the micro drip line to drip tubing, use our 1/4" barbed fittings.

  Some knowledge about drip irrigation systems can give a well-informed contractor or installer an advantage in a very competitive market. Many installations could benefit from the addition of drip irrigation, such as in strip planting, boxes, planters, sloped areas, windy areas, oddly shaped areas and green roofs.  Contractors or installers with expertise in micro irrigation can select the appropriate installation method and products for applications such as overlap irrigation on strip planting using micro drip line with pre-inserted drip emitters (in a variety of spacing and low flow rates), strip planting using a below grade drip system , containers and boxes using micro drip line with 6” to 9” spacing, a conventional irrigation method of PVC pipe with risers using multi outlet drip emitters or, for oddly shaped flowerbeds or closely spaced plantings, using  micro sprayers in a variety of flow rates and diameters. Each of these options provides the contractor with the tools and the flexibility to offer his customers installation packages that include a blend of options which set him apart from his competitors.

  Suggestions for below grade installation:

  Designed for use on small areas, such as containers, narrow plantings, green roofs, or oddly shaped layouts, the small diameter Micro-Line presents installation flexibility for many applications. 

  1. If automation is used and you will be running both drip and sprinkler zones, the controller should be selected with care. The ideal controller should have an independent program for each valve, or two to four programs for flexibility to use with each zone. Standard electric remote control valves model C0XX, or 3/4" (model C041) to 2” (model C044) battery operated controllers can be used in the installation, however, care should be taken to review the flow characteristics of the zone that the valve or controller will be accommodating.
  2. If use below grade, where it is feasible excavates the area to the depth recommended for the layout of the Micro Line drip line, or trench a ditch 2" to 4" deep for placing the micro Line, starting 2" to 4" from a curb.
  3. The Micro Line drip line should be first laid out in the field and secured into the ground using 1/4" plastic stakes before connecting the drip line to the manifold.
  4. If the system is installed below grade, an air vacuum relief valve is required. The air relief valve has been designed to allow air into a subsurface drip line after water is shut off to prevent clogging of below grade drip irrigation systems due to dirt suction under vacuum conditions. It also prevents infiltration of toxic substances into the drip system and allows the release of air from the system when the water is turned on. Install an air vacuum relief valve at the highest point of each zone
  5. Flushing: Prior to testing leave the end of the main line and the 1/4" drip laterals open.
     Partially back-filled the system leaving all joints and connections exposed. Then flush the system of all debris. Close the end line and all laterals.
  6. Pressure test the system with a minimum of 25 PSI prior to back-filling the drip line to identify leaks in the drip line, fittings and the drip zone.
