What it is

The flow switch inlet pipe is manufactured by Worcester Bosch for its RSF gas boiler range. It carries water into the flow switch assembly, where the switch senses demand and signals the boiler to fire. The part is supplied under version codes ANX, ANY, APH, API, AQN and ARN.

Signs this part needs replacing

  • Water weeping or staining around the flow switch inlet connection
  • Corrosion or pitting on the pipe surface
  • Scale or debris restricting flow through the pipe
  • Boiler failing to fire on a hot water demand because the flow switch is not actuated
  • Reduced hot water flow rate at the tap

Before you order

  • Confirm your appliance model and GC number against the fit list above
  • Check the version code on the existing pipe matches one of ANX, ANY, APH, API, AQN or ARN
  • Compare the part number 87161009640 with the marking on the component being replaced
  • Isolate the water and gas supplies before removal
