  • Prototype design, laboratory testing, field trials and approval of a standardized PE Syphon fitting for use on a low pressure PE gas distribution system.

The objective of this project is to achieve a G23 approved, final design of a standard PE Syphon fitting for use on new PE network which meets the following criteria:

  • Compatible with standard electrofusion jointing methods
  • Availability in various diameter bands (to be determined)
  • To be accessed via syphon stand pipe at road/footpath surface for liquid removal
  • Ability to be retro fitted to metallic distribution systems in cases of chronic water ingress investigation and rectification
The project will be deemed successful if:

  • A prototype/import of a PE syphon fitting that meets all criteria set out in the Objectives has been designed/identified, tested, trialed and gained G23 approval
