What it is

A central heating return pipe (CH) manufactured by Worcester Bosch, identified by part number 87161140820. It forms part of the heating circuit pipework on Worcester Greenstar Highflow 440CDI and 550CDI appliances, carrying returning system water back through the boiler.

Signs this part needs replacing

  • Visible weeping, drips or damp traces around the pipe connections
  • Corrosion, pitting or surface deterioration on the pipe
  • System pressure dropping repeatedly with no other obvious cause
  • Restricted flow or poor circulation traced to the return pipework

Before you order

  • Confirm the appliance model is a Greenstar Highflow 440CDI or 550CDI
  • Check whether the appliance is LPG or NG, as fitment differs between variants
  • Match the part number 87161140820 against the existing component before ordering
  • Verify the fault is with the return pipe rather than an adjacent joint or seal
