What it is

The ADAPTOR PUMP CONNECTION is a Worcester Bosch component used to join the circulation pump to the pipework on Greenstar Heatslave II appliances. It forms part of the hydraulic connection at the pump and is supplied under part number 87186898070. Correct fitment of this adaptor ensures a secure, leak-free joint between the pump body and the system pipework.

Signs this part needs replacing

  • Weeping or visible water tracking at the pump connection
  • Corrosion or scale build-up on the adaptor body or its threads
  • Staining or crusting around the joint after the appliance has run
  • Leaks that reappear after re-making the connection
  • Reduced system pressure traced to the pump connection area

Before you order

  • Confirm the appliance model against the fit list above, including whether it is an EXT variant
  • Check the part number 87186898070 matches the component being replaced
  • Inspect the pump connection and surrounding pipework for damage before fitting
  • Ensure the system is isolated, drained and depressurised before work begins
