EXCEL™, 100', 12" Spacing, 17 mm, .6 GPH , Drip Line with Check Valve
The Drip Store's 12” spacing, EXCEL pressure compensating drip line with check valve from DIG Corp is available in 100’ and with a flow rate of .6 GPH.
Part #: DL320-100CV
The Drip Store's Excel Pressure Compensating Drip Line with built-in check valve from DIG Corp is extruded tubing with self-contained, flow regulated emitters molded into the inside wall of the drip tubing in preset spacing. Both the tubing and the drip emitters are manufactured from the finest quality resins using a process to form a product that emits water uniformly from each emitter, year after year.
The Excel Inline PC drip emitters with built-in check valve contain a diaphragm that continuously adjusts to varying water pressure to ensure a constant flow rate. The diaphragm inside the inline drip emitter allows particles to pass through the dripper without harming it, providing reliable performance and a longer life. This method of continuous flushing and wide flow path allows the drip emitter to operate at optimal flow rates under extreme conditions. The PC inline drip emitters with built-in check valve discharge the same amount of water under a wide pressure range, providing high uniformity and longer run on any topography.
The Excel™ PC series Drip line drip emitters with built-in check valve or non-drain device have a sealing pressure of 1.5 PSI to prevent water draining out when the water has been turned off and opening pressure of 4.3 PSI when the pressure turn on. This feature protects the drip line from siphoning small soil particles into the drip emitter, making it ideal solution for sub-surface drip installation
For commercial and residential applications, use this drip line with our 17 mm barbed fittings and with our line of Nut Lock fittings. The PC drip line with built-in check valve 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. Our PC drip line with built-in check valve can be used for installation in planters, island, home gardens, trees, and in landscape areas.
Versatility: The Excel PC drip line with built-in check valve is designed for placement in both new and existing landscape areas including green-roof areas, and used for below ground or above the surface. The Excel PC drip line is ideal for installation on difficult terrain such as on slopes, in oddly shaped areas, and in windy sites.
Durability: Our Excel PC drip line with built-in check valve is designed to withstand the harshest field conditions, and is manufactured of high quality, highly durable plastics containing added quantities of carbon black compound, making it resistant to the damaging effects of ultraviolet rays.

Installation for Drip Line w/check Valve
Drip line installation:The 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 drip line to the drip tubing, use our 17 mm barbed drip fittings, or use our Nut Lock 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, sloped areas, windy areas or in oddly shaped areas. Contractors or installers with expertise in micro irrigation can select the appropriate installation method and products for applications such as overlap irrigation on slopes using drip line with pre-inserted drip emitters (in a variety of spacing and low flow rates), strip planting using a below grade drip system with check valve, shrubs and ground covers using drip line with 12” to 24” 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:
Depth, layout uniformity and drip lateral position are very important with Excel drip line installation. Installing the drip line too deep, uneven spacing between the laterals or positioning the laterals in sloping areasmay result in less water available near the surface, and uneven water distribution for germination, new plantings and transplanted or small plants, while too shallow a layout or positioning of the drip line may result in restricted maintenance practices that may result in damage to the drip line.
Where it is feasible excavate the entire area to the depth recommended for the layout of the drip line, or trench a ditch 4" to 5" deep for placing Excel drip line, starting 2" to 4" from sidewalk or curb.
If the system is installed below grade, an air vacuum relief valve is required (model A141). 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.
The Excel drip line should be first laid out in the field and secured into the ground using 1/2" plastic stakes before connecting the drip line to the manifold.
Flushing: Prior to testing leave the end of the main line and laterals open. Then the system should be partially back-filled, leaving all joints and connections exposed. Then flush the system of all debris, dirt and foreign matter. Close the end line and all laterals.
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.
The controllershould be selected with care, especially if it will be running both drip and sprinkler zones. The ideal controller will have an independent program for each valve, or two to four programs for flexibility of 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.
