Reliable automatic flush valve insert designed for Netafim Techline 17mm drip tubing. The TLFV-1 reduces clogging and maintenance by automatically flushing debris from dripline systems, helping maintain steady performance over time.

  • Compatibility: Insert inlet designed for 17mm Techline drip tubing with a barbed connection for a secure fit.
  • Flow capacity: Up to 15 GPM maximum zone flow rate per valve flush, suitable for typical irrigation zones.
  • Operating pressure: Works across a wide range — minimum 1.5 PSI to maximum 57 PSI for reliable operation.
  • Automatic operation: Reacts to flow to perform periodic flushing, eliminating the need for manual flushing routines.
  • Maintenance: Disassembles for winterization and cleaning to protect the dripline during off-season service.
  • Packaging: Sold individually; ideal for both repair and new-install applications.

Ideal for commercial and residential drip irrigation systems, the TLFV-1 supports long-term dripline performance by automatically removing sediment build-up that causes clogging. Install the insert in an accessible flush point or end-of-line location, follow manufacturer recommendations for placement and winterization, and confirm system flow rates do not exceed the valve’s 15 GPM per flush rating. Refer to the Netafim dripline components brochure or Netafim technical documentation for layout and CAD details.
