What it is

The 87186804520 pipe carries water from the flow sensor to the inlet on Worcester Bosch Greenstar Highflow 440CDI and 550CDI appliances. It is a Worcester Bosch pipe assembly that forms part of the boiler's hydraulic circuit between these two connection points. It is listed under the supplied product name PIPE - FLOW SENSOR TO INLET.

Signs this part needs replacing

  • Water weeping or visible traces of leakage at either end of the pipe
  • Corrosion, pitting or staining on the pipe body or at the connection points
  • Scale or debris build-up restricting flow through the pipe
  • Damage to the pipe, such as kinking, distortion or a disturbed connection
  • Flow sensor readings that suggest restricted or interrupted water movement through this section

Before you order

  • Confirm the appliance model is a Greenstar Highflow 440CDI or 550CDI
  • Check whether the boiler is the LPG or NG variant before ordering
  • Compare the part number on the existing pipe against 87186804520
  • Inspect both connection ends and the surrounding pipework for related faults before fitting
