It forms part of the water circuit on Greenstar CDI conventional gas boilers, carrying heated water away from the heat exchanger towards the system. It is listed within the gas boiler spares range as a pipe assembly.

Signs this part needs replacing

  • Visible water weeping or staining around the pipe, its unions or joints
  • Corrosion, pitting or scaling on the pipe surface
  • Restricted or reduced flow through the pipe, causing uneven heating or boiler performance faults
  • Physical damage such as kinks, cracks or deformation found during servicing

Before you order

  • Confirm the boiler model and GC number match one of the appliances listed above
  • Check the part number on the existing pipe or in the boiler documentation against 87107353590
  • Compare the connections, bends and overall shape of the new pipe with the removed component before fitting
  • Confirm whether the boiler is NG or LPG, as the model listing differs between fuels
