What it is

The pipe T-piece to inlet is a Worcester Bosch pipework component for the Greenstar Highflow range of high-efficiency combination boilers. It forms the T-junction within the inlet pipework assembly, directing flow between the connecting pipe runs on the appliance. It is supplied by Worcester Bosch under part number 87186804590.

Signs this part needs replacing

  • Visible weeping or water tracking at the T-junction or its connections
  • Corrosion, scale build-up or staining around the pipework joint
  • A loose or disturbed pipe run at the inlet assembly
  • Loss of system pressure traced to the inlet pipework area
  • Evidence of a previous repair or a damaged, distorted pipe end

Before you order

  • Confirm the appliance model and GC number against the fitment list before ordering
  • Check whether the boiler is an ErP or non-ErP build, as listed in the fitment data
  • Verify the gas type of the installation, as LPG and NG versions are both covered
  • Inspect the existing pipework to confirm the T-piece to inlet is the component required
