What it is

The Worcester Bosch 87107353240 is a return pipe that forms part of the internal pipework inside Worcester Bosch and British Gas badged gas boilers. It sits within the hydraulic circuit and routes water back through the appliance, keeping flow correctly directed between the heat exchanger, pump and the surrounding components. The part is supplied under the Worcester Bosch pipes and hoses spares range.

Signs this part needs replacing

  • Water weeping or visible staining around the pipe run inside the casing
  • Corrosion, pitting or scale build-up on the pipe surface or at the connection points
  • Pressure loss on the boiler gauge that cannot be traced to an external leak
  • Overheating or poor circulation where the return path is restricted or blocked
  • Damp patches or drips collecting on the base of the appliance

Before you order
