Lower dripline installation costs and experience an increase in water efficiency with the 17mm Dura Flo Check Valve Dripline (0.560" ID X 0.660" OD). Here's how. The engineered check valve design allows for lower opening pressures which means longer run lengths can be installed. This can reduce the amount of installation materials and labor. It also prevents low emitter drainage on shut down to minimize water loss. The dripline contains 0.9 GPH emitters spaced 18" apart; each emitter is designed with an anti-siphon feature to eliminate back-siphonage and prevent clogging. The pressure-compensating dripperline delivers a steady, uniform amount of water even if there are of changes in pressure, elevation, or length of dripline used. Tubing is made of polyethylene, emitters are made of polyethylene and silicone, all treated with UV inhibitors. Drip irrigation waters plants efficiently, reducing water usage by up to 70% compared to conventional sprinkler irrigation. Drip irrigation systems are easy to install, operate, and maintain, and can easily be automated. With proper installation of a drip system, water is delivered precisely to where plants need it most, and plants get the hydration they need for optimal growth and overall health. NDS is a leading manufacturer of drip and micro-irrigation solutions and the trusted brand of professional landscapers since 1972. The company offers a wide selection of water management solutions engineered for performance, durability, and ease of installation.

• Check valve design enables longer run lengths, which can reduce the amount of materials and labor; prevents low head drainage and keeps line charged
• Poly tubing is constructed using a layering method for durability: the outer layer, which is exposed to the sun, and the inner layer, which is exposed to water, is made of 100% virgin content; the middle layer is composed of recycled content
• Anti-siphon emitters prevent suction of debris and eliminates need for an air/vacuum relief valve
• Pressure compensating 0.9 GPH emitters are spaced 18" apart
• Roll is shrinkwrapped for easy handling and to ensure roll stays together as product is dispensed
• Delivers the same amount of water along the entire line even if the pressure changes; line is kept charged and won't drain out at low points; self-cleaning emitters are spaced evenly apart
• Ideal for watering closely spaced plants, hedges, vegetable gardens, planter boxes, and new plantings of ground cover; its flexibility also works as a watering ring for large pots and containers, and makes loops around large trees
• As part of a complete drip irrigation system, the dripline delivers water along the entire line, and each of the pressure-compensating emitters distributes water steadily even if the pressure changes
• Use tubing adapter to connect to water source; use 17mm insert fittings, Smart Loc multidiameter fittings, or 600 Series compression fittings to connect sections of dripline together, make bends, or add a tee intersection
• Periodically check for leaks or damage and replace or repair as needed; recommended operating pressure is up to 50 PSI; for areas with freezing temperatures, winterize by using an air compressor to evacuate lines with air to remove water
• Tubing made of polyethylene
• Emitters made of polyethylene and silicone
