What it is

The Worcester Bosch 87161026330 is a primary return pipe for the primary water circuit of Worcester 35 CDI II RSF gas boilers. It carries water returning from the heating circuit back towards the heat exchanger. It is supplied as a single pipe assembly.

Signs this part needs replacing

  • Visible weeping or water staining around the pipe joints and unions
  • Corrosion, pitting or surface deterioration on the pipe
  • Scale or sludge build-up restricting flow in the primary circuit
  • Repeated pressure loss requiring the boiler to be topped up
  • Kettling or circulation noise linked to a restricted primary return

Before you order

  • Confirm the appliance is a Worcester 35 CDI II RSF
  • Check whether the boiler is LPG or NG, as fitment is listed separately for each
  • Compare the part number against the existing pipe before ordering
  • Inspect the surrounding pipework and seals for damage that may also need attention
