What it is
The Worcester Bosch 87186642480 is a flow pipe from the manufacturer's hoses and pipes group. It forms part of the primary water circuit inside Greenstar CDi appliances, carrying heated water away from the heat exchanger and into the system pipework. It is a direct replacement item for the original pipe fitted at build.
Signs this part needs replacing
- Water weeping or dripping at the pipe connections or along the pipe run
- Corrosion, pitting or surface staining on the pipe wall
- Repeated loss of system pressure requiring regular top-ups
- Scale or sludge build-up restricting flow through the pipe
- Reduced heating performance or circulation noise traced to the pipework
