What it is

The Glow-worm pipework assembly for the expansion vessel (part number 0020118157) is a pipe component used on Betacom, Easicom and Ultimate gas boilers. It connects the expansion vessel to the boiler's heating circuit, allowing the vessel to absorb changes in system pressure as the water heats and cools.

Signs this part needs replacing

  • Water weeping or dripping from the pipework or its joints
  • System pressure dropping and needing regular topping up
  • Corrosion, scale or staining around the pipe connections
  • Kettling or unusual noise from the boiler as system pressure fluctuates
  • Visible distortion or damage to the pipe where it meets the expansion vessel

Before you order

  • Confirm your boiler model and GC number against the fitment list above
  • Check the part number 0020118157 on the existing component or in the manufacturer's parts list
  • Check whether the expansion vessel itself also needs replacing
  • Isolate the appliance and depressurise the heating circuit before removal
