Stop battling uneven watering, clogged emitters, and water waste. The Netafim Techline CV 17mm Emitter Tubing (12" Spacing, 0.92 GPH) is the professional's choice for flawless sub-surface drip irrigation and challenging slope applications. Engineered for decades of maintenance-free performance, this professional-grade dripline features a revolutionary built-in Check Valve (CV) that holds back up to 4.6 feet of elevation. This prevents the low-point drainage that plagues standard systems on hillsides, ensuring that every emitter across your entire zone activates and deactivates at the exact same time.
Designed to be installed with confidence underground, the Techline CV utilizes a patented physical root barrier to defend against root intrusion without the use of chemicals. Its advanced pressure-compensating (PC) emitters deliver a precise 0.92 GPH flow rate over a wide pressure range, guaranteeing perfect uniformity even on extensive lateral runs. Coupled with an integrated anti-siphon mechanism and a continuously self-flushing design, it actively repels dirt and debris, making it ideal for well water, commercial landscapes, green roofs, and high-traffic areas. When paired with standard 17mm barbed fittings, you are investing in the ultimate, clog-free watering infrastructure.

Install your 17mm Netafim Techline correctly for optimal performance.
Step 1: Connect to Source
Connect the tubing to your water source. Ensure your head assembly includes a 120-mesh irrigation filter and a pressure regulator that outputs between 14.5 and 58 PSI to properly activate the check valves.
Step 2: Layout & Trench
Lay the tubing on the surface or trench it below ground (typically 4-6 inches deep for turfgrass or garden beds). The physical root barrier allows you to safely bury the line without fear of intrusion.
Step 3: Attach 17mm Fittings
Use specialized 17mm barbed fittings to create corners, tees, or branch off from a solid PVC or poly mainline. Standard 1/2" fittings will not fit this tubing securely.
Step 4: Flush and Cap
Before capping the system, turn the water on to flush any dirt or debris out of the open lines. Once the water runs clear, terminate the ends using 17mm figure-eight line ends or end plugs.
What does "CV" stand for?
CV stands for Check Valve. Every emitter has an internal valve that keeps the line completely pressurized when the system shuts off, preventing low-point drainage.
This technology makes it the absolute best choice for sloped terrain, ensuring uniform watering from the top of the hill to the bottom.
Can this tubing be buried underground?
Yes! Netafim Techline CV is specifically engineered for sub-surface applications. The physical root barrier prevents roots from growing into the emitters, and the anti-siphon mechanism stops dirt from being sucked back into the line.
Burying the line eliminates evaporation and delivers water directly to the root zone, drastically reducing your overall water usage.
What fittings do I need for this tubing?
You must use standard 17mm barbed fittings. Standard 1/2" compression or Easy Loc fittings (which are sized for 0.700" OD tubing) are too large and will not create a watertight seal on this 17mm pipe.
Make sure all elbows, tees, and couplers are specifically rated for 17mm dripline.
How should I prepare my sub-surface Netafim system for spring planting?
As you prepare for spring watering, open the flush valves at the ends of your Netafim lines and run the system to thoroughly flush out any fine silt or sediment that accumulated over the winter.
Additionally, check and clean your 120-mesh irrigation filter at the head assembly to guarantee optimal flow and pressure as the growing season kicks off.
