Waterworks & Irrigation “IP” inflow protection mechanism for Bermad air valves


  • Simple and effective non-return mechanism
  • Completely non-metallic, making it suitable for high saline water
  • Female threaded on the outlet for connection to drain pipework
  • Designed to be fitted to pump suction lines on C10 air valves
  • Designed for Siphon pipelines to avoid air entry
  • Designed where no air intake is required on a pipeline, but air release.


The Bermad IP option is a mechanism that can be fitted to water or sewage air valves to ensure that air is only allowed to discharge.  The membrane prevents any air from being drawn into the pipeline, acting like a non-return valve.  The fitting has a 50mm M & F BSP thread and can be fitted to the Bermad model C10 / C30 and C50 air release valves.
