What it is

The expansion vessel tube, part number 0020020752, is a Glow-worm pipe component used on Flexicom gas boilers. It carries water between the expansion vessel connection and the boiler's hydraulic circuit, allowing the vessel to absorb expansion as system pressure rises. The tube is specific to the Flexicom range and is supplied as a single pipe assembly.

Signs this part needs replacing

  • Water weeping or dripping from the tube or its connections
  • Visible corrosion, pitting or staining along the pipe
  • Damp patches or scale deposits around the expansion vessel connection
  • Falling system pressure that cannot be traced to any other component
  • Kettling or air noise as the vessel connection draws in air

Before you order

  • Confirm your boiler model against the fit list above
  • Check the part number on the existing tube or in the manufacturer's parts list
  • Inspect the vessel connection and seals for damage before fitting
  • Verify the system has been depressurised and drained before removal
