Netafim TLFV-1 Flush Valve 1 Gallon 17mm Insert

Product Description

The NETAFIM TLFV-1 is a 17mm insert-style flush valve designed for use in drip irrigation systems. It mounts at the end of a lateral line and automatically flushes accumulated sediment and debris when system pressure drops below a set threshold. This keeps emitters and micro-irrigation components from clogging over time. The TLFV-1 connects directly to standard 17mm drip tubing via an insert fitting, requiring no tools beyond basic hand pressure for installation. Irrigation technicians and landscape professionals install this valve as a routine maintenance component on new and retrofit drip systems.

The TLFV-1 is suited for residential and light commercial drip irrigation laterals where end-of-line flushing is required. It is rated for a 1-gallon flush volume, which provides a controlled purge of the lateral each time the system cycles down. Typical applications include row crop drip tape systems, landscape drip zones, and subsurface irrigation layouts where sediment management is critical for emitter longevity.

Key Features

• Insert-style 17mm connection fits standard drip irrigation tubing without clamps or tools
• 1-gallon flush volume delivers a consistent end-of-line purge on system shutdown
• Automatic operation triggered by pressure drop — no manual intervention required
• Compact, lightweight design at 0.25 pounds for easy field handling and bulk installation
• Helps extend emitter service life by removing debris before it reaches emitter ports

Compatibility

Designed for use with 17mm drip irrigation lateral tubing in standard drip and micro-irrigation systems requiring end-of-line flush valve protection.

Installation Notes

Shut down the irrigation system and relieve line pressure before installing or replacing flush valves. The insert fitting pushes directly into the cut end of 17mm drip tubing — ensure a clean, square cut on the tubing for a secure seal. Install at the downstream end of each lateral line. Follow local irrigation and plumbing codes where applicable, and verify the flush valve outlet has unobstructed discharge to grade or a suitable drainage point.
