What it is

The DHW expansion vessel connection pipe is a Sime spare part, part number 6227630. It links the domestic hot water expansion vessel to the appliance's DHW circuit on the Sime boiler models listed below. The pipe carries the vessel connection and must be sound to keep the DHW side of the system sealed and correctly pressurised.

Signs this part needs replacing

  • Water weeping or dripping from the pipe or its connections
  • Visible corrosion, pitting or staining along the pipe run
  • Loss of DHW expansion vessel charge pressure with no fault at the vessel itself
  • Scale or debris build-up restricting flow through the connection
  • Joints that will not seal after re-making

Before you order

  • Confirm your appliance model against the Fits list above
  • Check the part number on the existing pipe or the manufacturer's parts list
  • Establish whether the leak is at the pipe, its joints or the expansion vessel before ordering
  • Inspect the vessel connection and surrounding pipework for damage that may also need attention
