What it is

The Worcester Bosch 87161203320 is a primary return pipe used in the CDI series of gas boilers. It forms part of the primary water circuit, carrying water back from the heating system to the heat exchanger. It is manufactured by Worcester Bosch for the 24 CDI and 28 CDI appliance range.

Signs this part needs replacing

  • Visible weeping or damp patches around the pipe or its joints
  • Corrosion, pitting or surface discolouration on the pipe
  • Scale or sludge build-up restricting flow in the primary circuit
  • Poor heating performance or boiler cycling linked to restricted primary flow
  • Joints that will not seal when re-made

Before you order

  • Confirm your boiler model and variant (NG or LPG, BF, OF or RSF) against the fit list
  • Check the part number on the existing pipe or in the manufacturer's parts list
  • Inspect the connecting joints and seals, as these may also need replacing
  • Verify the pipe routing matches your appliance before fitting
