The Netafim TLAVRV is a purpose-built air/vacuum relief vent that protects drip and subsurface irrigation lines by discharging trapped air during startup and admitting air when lines drain. It helps maintain accurate flow readings, prevents water hammer and vacuum collapse, and reduces the risk of contaminant intrusion.

  • Connection: 1/2" male pipe thread (MPT) for easy installation on Techline and other drip systems.
  • Performance: Discharges large air volumes before pressurization and admits air as lines drain for safe operation.
  • Construction: Corrosion-resistant, UV-stabilized composite materials with no metal parts to rust or corrode.
  • Pressure Rating: Suitable for typical landscape drip systems (manufacturer lists 140 psi maximum for 1/2" model).
  • Applications: Install at high points, before meters or valves, and in subsurface systems to protect piping and ensure meter accuracy.

Sold individually and compatible with common Techline fittings, the TLAVRV is a low-maintenance solution for preventing air-related irrigation problems. Consult system plans to locate vents at high points and before flow-measuring devices; see manufacturer documentation for full installation details and dimensional drawings.
