What it is

The PIPE CH RETURN is a central heating return pipe manufactured by Worcester Bosch, supplied under part number 8737603358. It forms part of the heating circuit pipework on Greenstar 2000 Combi GR2300iW appliances. The pipe carries returning heating water back through the boiler circuit.

Signs this part needs replacing

  • Visible water weeping or staining around the pipe run or its joints
  • Corrosion, pitting or scale build-up on the pipe surface
  • Pipe deformation, cracking or a pinhole leak under system pressure
  • Loss of system pressure that traces back to the return pipework

Before you order

  • Confirm the appliance model and output variant from the data badge
  • Check the fuel type (NG or LPG) matches the appliance being worked on
  • Verify the existing pipe is the return section and not another circuit pipe
  • Compare the part number 8737603358 against the marking on the removed component
