Netafim - Techline 17 mm Check Valve Dripline - Blank Tubing 100'

Techline CV 17mm dripline with built-in check valve is designed for maximum uniformity in subsurface and on-surface installations. Its pressure-compensating emitters and anti-siphon features ensure precision watering without low-point drainage, even on slopes. Ideal for commercial landscapes, sports fields, and areas with variable terrain or vandalism risk.

Key Features & Benefits

• 2 PSI check valve in each emitter prevents low-point drainage, ideal for slopes
• Pressure-compensating emitters deliver uniform flow from 14.5–58 PSI
• Continuous self-flushing design prevents clogging throughout operation
• Anti-siphon feature protects against debris ingestion due to vacuum
• Offset flow path and raised outlet prevent root intrusion—no chemicals needed
• Emitter flow rates: 0.26, 0.4, 0.6, 0.9 GPH

Construction & Durability:

• UV-resistant, flexible tubing adapts to any planting area shape
• Self-contained one-piece construction for reliable, easy installation
• Qualifies for LEED projects with post-consumer and post-industrial recycled content

Ease of Installation & Use:

• No need for air/vacuum relief vent or automatic flush valve for subsurface use
• Flexible 7” bending radius for quick layout in curved or tight areas
• Compatible with standard drip fittings and 17mm insert components
