Netafim Techline CV: Precision Drip Irrigation for Any Landscape, From Slopes to Subsurface

Achieving a perfectly watered landscape is a challenge. Uneven terrain leads to dry spots at the top of a slope and waterlogged zones at the bottom. Long irrigation lines often deliver inconsistent flow, overwatering plants near the source and underwatering those at the end. Traditional irrigation methods can be inefficient, leading to runoff, evaporation, and wasted water. Netafim Techline CV is the definitive, professional-grade solution engineered to conquer these challenges, delivering precise, uniform hydration to every plant in any environment. From residential lawns and intricate flower beds to commercial sports turf and demanding green roof applications, Techline CV provides unparalleled reliability and water efficiency.

The Techline CV Advantage: Why Professionals Trust Netafim

Netafim, the pioneer of drip irrigation, has engineered Techline CV to be the most advanced and reliable dripline on the market. Its performance is built on a foundation of proprietary technologies that work in concert to deliver water with unmatched precision and uniformity, ensuring system longevity and minimal maintenance.

Unrivaled Water Uniformity on Slopes and Long Runs

The core of Techline CV's superior performance lies in its dual-technology emitters. This system is specifically designed to overcome the physical challenges of gravity and friction loss that plague standard irrigation systems on uneven ground or over extended distances.

First, the Pressure-Compensating (PC) diaphragm within each emitter ensures a constant, precise flow rate across a wide pressure range, from 14.5 to 58 psi. This means the last emitter on a 300-foot run receives the same amount of water as the first, and plants at the bottom of a hill receive the same hydration as those at the top. This eliminates the guesswork and ensures every part of the landscape thrives equally.

Second, the integrated 2 psi Check Valve (CV) in every emitter acts as a tiny one-way gate. When the system shuts down, this valve closes, holding back up to 4.6 feet of elevation change in the line. This critical feature accomplishes two things: it prevents low-point drainage, which eliminates wasteful puddling and soil erosion at the lowest point of the zone, and it keeps the entire dripline fully charged with water. The result is instant, uniform watering across the entire zone the moment the system is turned on, with no delay for lines to refill. This combination of PC and CV technology makes Techline CV the industry's premier solution for irrigating slopes and complex terrain.

Engineered for a Lifetime of Clog-Free, Low-Maintenance Operation

A primary concern for any drip system, especially those installed subsurface, is long-term reliability and the prevention of emitter clogging. Techline CV is engineered with a multi-faceted defense system to ensure years of trouble-free operation.

The foundation of this system is the Continuous Self-Flushing Emitter Design. Unlike systems that only flush at the beginning or end of a cycle, Techline CV's emitters are designed to detect and purge debris during operation, ensuring an uninterrupted flow path and consistent performance.

For subsurface installations, two additional features provide critical protection. The Anti-Siphon Feature prevents dirt, sand, and other external contaminants from being drawn into the emitter when the system creates a vacuum at shutdown. Furthermore, a Unique Patented Emitter with a Physical Root Barrier provides a chemical-free defense against root intrusion. The emitter's offset flow path, extra-large bath area, and raised outlet create a formidable physical obstacle, deterring roots without relying on chemical treatments, making it a safe and permanent solution.

Versatile by Design: On-Surface Durability, Subsurface Precision

Techline CV is engineered for maximum versatility, performing flawlessly whether it is laid on the surface and covered with mulch or buried directly in the root zone. The tubing is constructed from a durable, flexible polyethylene that is highly resistant to UV radiation, ensuring it will not degrade under direct sun exposure. Its exceptional flexibility, allowing for a tight 7-inch bending radius, makes installation in curved, angular, or narrow planting areas simple and efficient, adapting to any landscape design without kinking or compromising flow. The self-contained, one-piece construction further simplifies installation, providing a reliable and robust dripline for any application.

A Commitment to Sustainability and Quality

Choosing Netafim Techline CV is an investment in both landscape health and environmental responsibility. The tubing is manufactured using post-consumer recycled materials, contributing to a more sustainable supply chain. This commitment to green engineering makes Techline CV eligible for use in LEED-certified projects, meeting the stringent requirements for sustainable building and landscaping. Netafim's dedication to quality is demonstrated by its compliance with ISO 9261 standards and is backed by an industry-leading warranty: seven years for defects in materials and workmanship, and ten years for environmental stress cracking.

Applications and Ideal Use-Cases

Techline CV's advanced features make it the ideal choice for a vast array of irrigation projects. Its adaptability allows it to provide a superior watering solution for virtually any landscape need.

Perfect for Residential Landscapes

• Lawns & Turfgrass: Delivers water directly to the roots for a healthier, greener lawn with less water lost to evaporation.
• Flower Beds & Shrubs: Provides gentle, precise watering that promotes deep root growth and vibrant blooms.
• Vegetable Gardens: Ensures consistent moisture levels, critical for maximizing yield and quality.
• Sloped Hillsides & Terraces: Eliminates runoff and ensures even water distribution on challenging terrain.
• Watering Rings for Trees: Can be looped around trees to establish new plantings or provide deep watering to mature specimens.

The Go-To for Commercial & Specialty Projects

• Sports Turf & Golf Courses: Maintains pristine, durable turf in high-traffic, high-performance areas.
• Medians & High-Traffic Areas: Offers a safe, low-profile, and vandal-resistant irrigation solution.
• Green Roofs & Living Walls: Provides a lightweight, efficient watering system for specialized architectural installations.
• LEED-Certified Projects: Meets sustainability requirements for water efficiency and recycled material content.
• Narrow or Angular Planting Areas: The tubing's flexibility allows it to conform to complex and tight landscape designs.

The Solution for Challenging Soil Conditions

Proper irrigation depends heavily on soil type. Techline CV's range of flow rates provides an optimal solution for any soil condition. For dense, heavy clay soils that absorb water slowly, the low-flow 0.26 and 0.4 GPH emitter options are ideal. This slow application rate matches the soil's infiltration capacity, preventing wasteful surface runoff and allowing water to penetrate deep into the root zone. For loamy or sandy soils, higher flow rates like 0.6 and 0.9 GPH can be used to efficiently deliver the required water volume.
