What it is

The expansion vessel connection pipe is a manufacturer-supplied pipe for Biasi gas boilers, linking the expansion vessel to the boiler's heating circuit. It carries water between the vessel and the primary system, allowing the vessel to absorb pressure changes as the system heats and cools. The part is listed under expansion vessels within Biasi boiler spares.

Signs this part needs replacing

  • Water weeping or staining at the pipe connections to the expansion vessel
  • Visible corrosion, pitting or hairline cracking along the pipe
  • Pressure loss on the heating circuit with no other obvious source
  • Pipe deformation or damage found when the vessel is removed or replaced

Before you order

  • Confirm the boiler model and GC number against the fitment list above
  • Check whether the pipe or its unions are the source of the leak before ordering
  • Inspect the expansion vessel connection and seals for wear while access is available
