What it is

This is the connecting pipe that links the expansion vessel to the hydraulic circuit on a range of Sime gas boilers. It carries water between the vessel and the main appliance pipework, allowing the expansion vessel to absorb pressure changes as the system heats and cools. The part is manufactured by Sime and identified by part number 6227694.

Signs this part needs replacing

  • Visible water weeping or staining at the pipe unions or along the pipe run
  • Corrosion or pitting on the pipe surface, particularly at the connection points
  • Scale or debris build-up restricting flow through the pipe
  • Repeated loss of system pressure that cannot be traced to other components
  • Kinking, cracking or deformation of the pipe

Before you order

  • Confirm the appliance model and serial details against the fitment list above
  • Check the existing pipe for damage at the unions as well as the pipe body
  • Verify the part number 6227694 matches the number on the component being replaced
  • Confirm whether any seals or washers at the connections also need attention
